Answer:
5 forks2 spoonsStep-by-step explanation:
The higher-cost item is forks, so we can let x represent the number of those that are purchased. The total number purchased is 7, so the number of spoons purchased is (7-x).
The total cost is the sum of the costs for each of the items:
6x +5(7-x) = 40
x +35 = 40 . . . . . . simplify
x = 5 . . . . . . . . . . . subtract 35; the number of forks
7-x = 2 . . . . . . . . . the number of spoons
Daniel bought 5 forks and 2 spoons.
_____
Additional comment
Since $40 is not divisible by $6, we can guess that the number of forks Daniel bought will be a multiple of 5. That is, Daniel bought 0 or 5 forks. If he bought 0 forks, then he must have bought 40/5 = 8 spoons, so that is not a viable choice. The only number of forks that makes sense in this problem is 5 forks, so 2 spoons--numbers that total 7, as required.
just please help help help help

In 1970, the median home value was $20,000. By 2020, the median home value was $320,000. What is the percent increase in home value in those 50 years?
Answer:
1500%
Step-by-step explanation:
The formula for Percentage increase is
Increase/ Initial Amount × 100
Increase = Current Amount - Initial Amount
Increase = $320,000 - $20,000
Increase = $300,000
Percentage Increase =
$300,000/$20,000 × 100
= 1500%
The percent increase in home value in those 50 years is 1500%

In a right triangle the length of a hypotenuse is c and the length of one leg is a, and the length of the other leg is b, what is the value of b, if c=5, a=3
Answer:
b = 4
Step-by-step explanation:
Try setting up the equation of the pythagorean theorem.
hypotenuse^2 = leg(a)^2 + leg(b)^2
c^2 = a^2+b^2
Now substitute what you know and solve for the unknown.
5^2 = 3^2+b^2
25 = 9 + b^2
b^2 = 25-9 = 16
b = 4.

(-5,5)(5,0) help pls need the work shown as well ahaha!
Answer:
-1/2
Step-by-step explanation:
Formula to find slope is y2-y1/x2-x1
Chose one ordered pair to be the 2 and the other one to be the 1
I chose the 2nd one to be 2.
Plug in the y-value from the 2nd ordered pair to y2 because its the 2.
Plug in the x-value from the 2nd ordered pair to x2 because its the 2.
Now you have 0-y1/5-x1
Do the same thing but for the 1.
Plug in the y-value from the 1st ordered pair to y1 because its the 1.
Plug in the x-value from the 1st ordered pair to x1 because its the 1.
Now you have 0-5/5--5
In this situation, you have 2 minus signs.
2 minus = 1 positive.
Now you have 0-5/5+5
Simplify.
Now you have -5/10.
Simplify.
-1/2.
Hope this helps!

Determine whether each number is a solution of the
given inequality
8m - 6 < 10
when m = 3
O YES (m = 3 is a solution of the inequality)
o NO (m = 3 is not a solution of the inequality)
Answer:
NO (m = 3 is not a solution of the inequality)The line graph is also attached below.
Step-by-step explanation:
Given
[tex]8m-6<10[/tex]
Add 6 to both sides
[tex]8m-6+6<10+6[/tex]
Simplify
[tex]8m<16[/tex]
Divide both sides by 8
[tex]\frac{8m}{8}<\frac{16}{8}[/tex]
Simplify
[tex]m<2[/tex]
Therefore, m = 3 NOT a solution of the inequality because 'm' must be less than 2.
Hence,
NO (m = 3 is not a solution of the inequality)VERIFICATION:
Given
[tex]8m-6<10[/tex]
substitute m = 3
8(3) - 6 < 10
24 - 6 < 10
18 < 10

NEED HELP A triangle is cut from a rectangle. The height of the triangle is half of the unknown side length s. The area of the shaded region is 84 square inches. Write an equation you can use to find the side length s. An equation is =84.
Answer: 14s - 7s/2 = 84
Step-by-step explanation:
Given that s is the length of the unknown side:
Area of the shaded region = 84
Area of rectangle - Area of triangle = 84
Area of rectangle = L * W
= 14 * s
= 14s
Area of triangle = ¹/₂ * base * height
= ¹/₂ * 14 * s/2
= 7s/2
Area of shaded region:
14s - 7s/2 = 84
Solving for s:
14s - 7s/2 = 84
28s - 7s = 168
21s = 168
s = 168/21
s = 8 inches

2 1/3 feet : 4 1/2 feet
Answer:
14/27 feet
Step-by-step explanation:
2 1/3 feet : 4 1/2 feet
= 7/3 : 9/2
= 7/3 ÷ 9/2
= 7/3 × 2/9
= (7*2)/(3*9)
= 14/27 feet
2 1/3 feet : 4 1/2 feet = 14/27 feet
