Answer:
x<3
Step-by-step explanation:
Let's solve your inequality step-by-step.
0>3x−3−6
Step 1: Simplify both sides of the inequality.
0>3x−9
Step 2: Flip the equation.
3x−9<0
Step 3: Add 9 to both sides.
3x−9+9<0+9
3x<9
Step 4: Divide both sides by 3.

Tara and Ashley spent the same amount at the grocery store. Tara bought 5 pounds of apples. Ashley bought 3 pounds of apples and $5 worth other groceries. How much does one pound of apples cost?
Answer:
one pound of apple cost $2.5
Step-by-step explanation:
Let the amount they both spent at the grocery store be y and x be the price of apples per pound.
Since Tara bought 5 pounds of apples, 5x = y (1) and Ashley bought 3 pounds of apples and $5 worth other groceries, 3x + 5 = y (2).
Equating both expressions, 5x = 3x + 5
collecting like terms,
5x - 3x = 5
2x = 5
dividing both sides by 2, we have
x = 5/2
x = 2.5
So one pound of apple cost $2.5

Martin has a total of 19 nickels (50.05) and dimes ($0.10) worth $1.65. How many of each type of coin does he have?
can put your work too
Answer: 19nickels and 7dimes.
Ps i really don’t know where the 50.05 came from if it is suppose to be there then I really don’t know how to solve this.
Step-by-step explanation:
Ok so if you know that there are 19nickels, let n=number of nickels.
The number of total coins subtracted by number of nickels will give you number of dimes.
165-number of nickels=number of dimes
Value of dimes=10(number of dimes) or total value of dimes/individual value (10cent)
Then you can substitute total as $1.65 and get the value of nickels by multiplying by 5cent ( my teacher taught me using whole numbers to make it easier so I turned $1.65 to 165 cent). Since the value of the dimes is the value of nickels subtracted from the total, I can subtract 95 from 165 and divide the difference by 10, to get the number of dimes.
5(n)=5(19)=95
(165-95)/10=number of dimes
70/10=7dimes
You can check by multiplying 7x10 and 5x15 again and adding them together to see if they equal 165 cent.
Solve for x and y if this is what’s given to you
Answer:
x=7; y=21
Step-by-step explanation:
These angles are congruent so:
7y-3=2x+4
We need to find x, and AB and DC are congruent, so:
3x+3=6x-18
Add 18 to both sides:
3x+21=6x
Subtract 3x from both sides:
3x=21
Divide by 3:
x=7
Substitute:
7y-3=2(7)+4
Simplify Like-Terms:
7y-3=18
Add 3 to both sides:
7y=21
Divide both sides by 7:
y=21

What is 5/6 of 1/2?
A. 5/12
B. 6/12
C. 5/8
D. 6/8
Answer:
5/12
Step-by-step explanation:
of means multiplication. so multiply 5x2 / 6x2 which is 5/12
Answer:
A. 5/12
Step-by-step explanation:
the "of" in the answer is asking you to multiply.
what you want to do is multiply the numerators and denominators.
5 x 1 = 5
6 x 2= 12
giving you 5/12!

Answer:

Step-by-step explanation:
I'm going to explain this thoroughly because it seems like you don't have a full understanding of how to do this...practice makes perfect though!
-5+g=-2
The entire point of completing an algebra problem is to find what the variable equals, which means that we need to get the variable by itself. In this case, the variable is g.
The only other thing that is next to g is -5, so we need to add 5 because it is the opposite of subtracting (the sign also always changes when something crosses to the other side of the equation).
-5+g=-2
+5 +5
g=3
This is the solution! I would suggest that you practice these type of small algebra problems if you really don't understand c:

A shop owner offered a 20% discount off the regular price of a lamp. The amount of the discount is $25. What is
the regular price of the lamp?
please answer this questions fast
Answer:
5. 216, 1416
6. 448.5 g
Step-by-step explanation:
5.
Price of 1 item: 1200
GST = 18%
18% of 1200 =
= 0.18 * 1200
= 216
Amount of tax: 216
Total price = original price + GST
Total price = 1200 + 216 = 1416
6.
Weight of 1 item: 17 1/4 g
Weight of 26 items = 26 * 17 1/4 g
26 * 17.25 g = 448.5 g

Answer: My answer is in the bottom :)
Step-by-step explanation:8(1 + 8z) do the distributive property
8+64z=72z or 8=64z
64 64
1/8=z
What is the value of x?
Answer:
x = 6
Step-by-step explanation:
The Pythagorean Theorem states that a² + b² = c². In this case, c would be the hypothenuse or the longest side, which is 10. 8 can be either a or b.
a² + b² = c²
a² + 8² = 10²
a² + 64 = 100
a² = 36
a = √36
a = 6
So, x = 6.

Help me find the values of k and p please
Answer:
B
Step-by-step explanation:
The lines marked with ||| are equal. That means that 2P + 7 equals 17
2P + 7 = 17 Subtract 7 from both sides.
2P + 7 - 7 = 17 - 7 Combine
2P = 10 Divide by 2
P = 5
3k - 5 and 28 are marked with one | That means that they are equal
3k - 5 = 28
3k = 28 + 5
3k = 33
k = 33/3
k = 11
The answer is B
Can somebody please solve this problem. I need help
Answer:
X=4
Step-by-step explanation:
4(x+12) = 19x-12
4x+48= 19x-12
sub 4x from both sides
48= 15x-12
add 12 to both sides
60=15x
divide 15 from both sides
and 60/15 =4
Answer:
[tex]4(x + 12) = 19x - 12 \\ 4x + 48 = 19x - 12 \\ 4x - 19x = - 12 - 48 \\ - 15x = - 60 \\ x = \frac{60}{15} \\ x = 4[/tex]

Answer:
Point-Slope: y+1=-5/7(x-5)
Slope Intercept: y=-5/7x+ 2 4/7
Standard: -5x+7y=18
Step-by-step explanation:
Slope: -5/7
Point slope is when the equation is in y-y1=m(x-x1) form.
I used the point (5,-1) but it really doesn't matter which one
Substitute it into (x1,y1)
y--1=-5/7(x-5)
y+1=-5/7(x-5) **2 minus signs is equal to 1 plus sign**
Slope-intercept is when the equation is in y=mx+b form.
y=-5/7x+b
To solve for b, plug in one of the points (again, I choose to use (5,-1)
(-1)=-5/7(5)+b
-1=-25/7+b is equal to asking -1=-3 4/7+b
b=2 4/7
Standard form is when it is in Ax+By=C
We'll covert from slope intercept to standard: y=-5/7+ 2 4/7
y=-5/7x+ 2 4/7 is the same as y=(-5/7x+ 18/7)
7y=5x+18 **Multiply both sides by 7, the common denominators**
-5x+7y=18 **Subtract 5x from both sides**

Answer:
f(x) = 3x
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( m is the slope )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (1, 3)
m = [tex]\frac{3-0}{1-0}[/tex] = 3 , then
y = 3x ← is the equation of the graphed line
