Answer:
The watermelon candies taste $0.13 more.
Step-by-step explanation:
First, in order to find out how much each candy costs per ounce, you have to take the cost and divide it by the number of ounces. 3.48 divided by 12 is 0.29, so the watermelon candies cost $0.29 per ounce. 1.38 divided by 8 is 0.16, so the chewy chocolates cost $0.16 per ounce. In order to find how much more the watermelon candies cost, we have to subtract the cost of the watermelon candies by the cost of the chocolate candies. 0.29-0.16=0.13, so the watermelon candies cost $0.13 more than the chocolate candies.

Step-by-step explanation:
Determine the x- and y-intercepts of the graph of x+2y=−4 . Then plot the intercepts to graph the equation.
Answer:
To determine the y-intercept, convert the equation into slope-intercept form.
x + 2y = -4
Subtract x from both sides
2y = -x-4
divide by 2 on both sides
y = -1/2(x) - 2 (this is the formula, with a slope of -1/2 and y-intercept of -2
This gives you a y-intercept of -2, which can be plotted at (0, -2)
For the x-intercept, plug in 0 for y into the formula.
x + 2y = -4
x + 2(0) = -4
x + 0 = -4
x=-4
This gives you an x-intercept of -4, which can be plotted at (-4, 0). Put those two numbers on the line and graph it, remembering that your slope is -1/2

In order to solve this equation, you have to use the multiplication property of equations. This means that you have to not only multiply the exponents, but also the 5. The variable (x) stays the same, as the only components that have to be multiplied are the exponents and the number 5.
Hope this helps!

Answer:
Step-by-step explanation:
To find the first table y = 4x + 2, to find each y value we have to substitute each x value into the equation.
4(-2) + 2 = -6 so -2 is going to have the y as -6
4(-1) + 2 = -2 so -1 is going to have the y as -2
4(0) + 2 = 2 so 0 is going to have the y as 2
4(1) + 2 = 6 so 1 is going to have the y as 6
4(2) + 2 = 10 so 2 is going to have the y as 10
So these are the points you would graph (-2, -6), (-1, -2), (0, 2), (1,6), and (2, 10)
For the next talbe y = 3x + 1 we do the same thing
3(-2) + 1 = -5 so -2 is going to have the y as -5
3(-1) + 1 = -2 so -1 is going to have the y as -2
3(0) + 1 = 1 so 0 is going to have the y as 1
3(1) + 1 = 4 so 1 is going to have the y as 4
3(2) + 1 = 7 so 2 is going to have the y as 7
The ooints to graph are (-2, -5), (-1, -2),(0,1), (1, 4) and (2,7)
For the next table y = 6x - 5
6(-2) - 5 = -17 so -2 is going to have the y as -17
6(-1) - 5 = -11 so -1 is going to have the y as -11
6(0) - 5 = -5 so 0 is going to have the y as -5
6(1) - 5 = 1 so 1 is going to have the y as 1
6(2) - 5 = 7 so 2 is going to have the y as 7
The points to graph (-2, -17), (-1, -11), (0, -5), (1, 1) and (2, 7)
For the next table y = 5 + 2x
5 + 2(-4) = -3 so -4 is going to have the y as -3
5 + 2(-2) = 1 so -2 is going to have the y as 1
5 + 2(0) = 5 so 0 is going to have the y as 5
5 + 2(3) = 11 so 3 is going to have the y as 11
5 + 2(5) = 15 so 5 is going to have the y as 15
(-4, -3), (-2, 1), (0, 5), (3, 11) and (5, 15)
For the next table y = 8x - 10
8(-4) - 10 = -42 so -4 is going to have the y as -42
8(-2) - 10 = -26 so -2 is going to have the y as -26
8(0) - 10 = -10 so 0 is going to have the y as -10
8(2) - 10 = 6 so 2 is going to have the y as 6
8(4) - 10 = 22 so 4 is going to have the y as 22
(-4, -42), (-2, -26), (0, -10), (2, 6) and (4, 22)
For the last table
2(-2) = -4 so -2 is going to have the y as -4
2(-1) = -2 so -1 is going to have the y as -2
2(0) = 0 so 0 is going to have the y as 0
2(-1) = -2 so -1 is going to have the y as -2
2(-2) = -4 so -2 is going to have the y as -4
(-2, -4), (-1, -2), (0, 0), (-1, -2) and (-2, -4)
Please help im just a middle schoolor!!!!! The distance between City A and City B is miles. A length of feet represents this distance on a certain wall map. City C and City D are feet apart on this map. What is the actual distance between City C and City D? The actual distance between City C and City D is ???? Miles.
Please help im just a middle schoolor!!!!! The distance between City A and City B is 250 miles. A length of 1.7 feet represents this distance on a certain wall map. City C and City D are 3.74 feet apart on this map. What is the actual distance between City C and City D?
Answer:
Distance between City C and City D is 550 miles
Step-by-step explanation:
Given that:
City A and City B are 250 miles apart with a length of 1.7 feet; &
City C and City D are x miles apart with a length of 3.74 feet.
To find the distance ( in x miles) between City C and City D, we use the ratio or proportionality concept.
i.e
250 miles = 1.70 ft
x miles = 3.74 ft
By cross multiplying, we get:
(250 * 3.74) = ( x * 1.70)
x = (250 * 3.74)/ 1.70
x = 550 miles.
Thus, the distance between City C and City D is 550 miles

What is the solution to the equation 3/5(y-5) = - (y+3) +2
Answer:
[tex]\frac{5}{4}[/tex]
Step-by-step explanation:
Given expression:
[tex]\frac{3}{5}[/tex](y - 5) = - (y + 3) + 2
To solve this problem, multiply both sides by 5;
5 x [tex]\frac{3}{5}[/tex](y - 5) = 5[-(y + 3) + 2}
3(y - 5) = 5(-y - 3 + 2)
expand,
3y - 15 = 5(-y -1)
3y -15 = -5y - 5
Collect like terms;
3y + 5y = -5 + 15
8y = 10
y = [tex]\frac{10}{8}[/tex] = [tex]\frac{5}{4}[/tex]

Dependent variable : _____________________________ Solution: ___________________________ independent variable : ___________________________ write the function: ________________________________
Answer:
$66Step-by-step explanation:
Step one:
given data
charges
$4 per bag
$10 weekly fee
let the number of bag be x
and let the total charges be y
the linear function for the total per week is
y=4x+10
Step two:
the independent variable is the weekly fee of $10
for x=14
y=4(14)+10
y=56+10
y=$66
Heidi uses 5 grams of tea leaves to make 25 fluid ounces of tea. Last week she made 75 fluid ounces of tea. How many grams of tea leaves did Heidi use to make tea last week?
Given :
Heidi uses 5 grams of tea leaves to make 25 fluid ounces of tea.
Last week she made 75 fluid ounces of tea.
To Find :
How many grams of tea leaves did Heidi use to make tea last week.
Solution :
Let, x gram of leaves are required last week.
So,
[tex]\dfrac{x}{5}=\dfrac{75}{25}\\\\x = 5\times\dfrac{75}{25}\\\\x = 5\times 3\\\\x = 15 \ grams[/tex]
Therefore, 15 grams of tea leaves is used last week.
Hence, this is the required solution.
How can you solve standard form and intercept form?
Answer:
The standard form of such an equation is Ax + By + C = 0 or Ax + By = C. When you rearrange this equation to get y by itself on the left side, it takes the form y = mx +b. This is called slope intercept form because m is equal to the slope of the line, and b is the value of y when x = 0, which makes it the y-intercept.

Given expression
9x² - 2(k + 7)x + kIf this is a perfect square then it should be in the form of:
(3x)² - 2(3x)(√k) + (√k)²Comparing the two expressions, we see that:
(k + 7) = 3√k(k + 7)² = 9kk² + 14k + 49 - 9k = 0k² + 5k + 49 = 0D = √(5² -4*49) = √-171Since the discriminant is negative, there is no solution

Jason buys three shirts with a listed price of $20 each. Jason uses a coupon that provides "Buy Two, Get One Free". What is the total final price Jason pays?
Given:
Jason buys three shirts with a listed price of $20 each.
He uses a coupon that provides "Buy Two, Get One Free".
To find:
The total final price Jason pays.
Solution:
Total number of shirts he buys = 3
Since he uses a coupon that provides "Buy Two, Get One Free", therefore he need to pay for 2 shirts and 1 he will get free.
Cost of 1 shirt = $20
Cost of 2 shirts = 2 × $20
= $40
Therefore, total final price Jason pays is $40.

On Olga's 16th birthday, her uncle invested $2,000 in an account that was locked into a 1.75% interest rate, compounded monthly. How much will Olga have in the account when she turns 18? Round to the nearest cent.
Answer:
$2070.6Step-by-step explanation:
Step one:
given data
principal p= $2000
Rate r= 1.75% = 0.0175
time t= 18-16= 2years
Required
The final amount of the compounded principal
The compound interest formula is
A=P(1+r)^t
A=2000(1+0.0175)^2
A=2000(1.0175)^2
A=2000*1.0353
A=2070.6
The account when she turns 18 will be $2070.6
