Your favorite cookie contains 10 grams of fat. If you eat no less than 4 cookies and no more than 7 cookies, how many grams of f

Sergio039 [100]

Well, if each cookie contains 10g of fat, then...

4 cookies = 4*10 = 40g fat

7 cookies = 7*10 = 70g fat

I can only eat 4 to 7 cookies. So that means I had between 40 and 70 grams of fat.

Answer: a. Between 40 and 70 grams.

13. The perimeter P (in yards) of a soccer field is represented by the formula P = 24 + 2w,

rjkz [21]

Answer:

$w = \frac{1}{2}(P - 24)$

$w = 153\ yards$

Step-by-step explanation:

Given

$P = 24 + 2w$

Require

Solving (a):

$P = 24 + 2w$

Subtract 24 from both sides

$P-24 = 24-24 + 2w$

$P-24 = 2w$

Divide both sides by 2

$\frac{1}{2}(P - 24) = \frac{2w}{2}$

$\frac{1}{2}(P - 24) = w$

$w = \frac{1}{2}(P - 24)$

Solving (b):

Substitute 330 for P un the expression in (1)

$w = \frac{1}{2}(330 - 24)$

Evaluate the bracket

$w = \frac{1}{2}(306)$

$w = 153\ yards$
