Answer:

Step-by-step explanation:

1 pound = 16 ounce

6 pound = 6 * 16 = 96 ounces

Cost of 96 ounces of grapes = $18

Cost of 1 ounce of grape = 18/96

Cost of 72 ounces of grape = 18*72 / 96 = 27/2

= $13.50

Direct Proportion because is weight increase, the cost will increase

96:18 = 72 : x

Product of means = Product of extremes

18*72 = x*96

18*72/96 = x

x =$13.50

16. Solve the equation. Check the solution.

Hi there

a/(a² - 36) + 2/(a-6) = 1/(a+6)
a/(a+6)(a-6) + 2/(a-6) = 1/(a+6)
Now we need to multiply the terms by (a+6)(a-6)
a + 2(a+6) = 1(a-6)
a + 2a + 12 = a - 6
3a + 12 = a - 6
3a - a = -6 - 12
2a = -18
Divide both sides by 2
2a/2 = -18/2
a = -9
Thus, The correct option is A

I hope that's help !

Good luck !

When you add 18 to 1/4 of a number you get the number itself

JulijaS [17]

X - the number

$\frac{1}{4}x+18=x \\
18=x-\frac{1}{4}x \\
18=\frac{3}{4}x \ \ \ |\times \frac{4}{3} \\
18 \times \frac{4}{3} = x \\
6 \times 4=x \\
x=24$

The number is 24.
