Answer:
40/.40 = 100
You can buy 100 pounds of food.
Step-by-step explanation:
We have the following equation:
s = ut + 1 / 2at ^ 2
Clear a for the equation:
1 / 2at ^ 2 = s-ut
at ^ 2 = 2s-2ut
a = 2s / t ^ 2-2ut / t ^ 2
Rewriting:
a = (2s-2ut) / (t ^ 2)
Answer:
An equation that represents a in terms of other variables is:
C. 2s-2ut / t ^ 2
This is the same as any math problem you may have solved before.
First, start by isolating the x on one side. I will choose to keep the coefficient positive, so I will add x to both sides.
6>2x+2
Subtract 2
4>2x
Divide by 2
2>x
Or
x<2
Answer:
6. b. 50
7. d. 12
Step-by-step explanation:
6. 80% is equal to 0.8.
0.8x =40.
Divide 0.8 by 40 to get x.
x=50.
7. If he needs 3 eggs for 30 cookies, we divide 120 by 30 to get 4.
We multiply 4*3 to find the total amount of eggs needed.
4*3= 12
