752/12 = 62.66 and since she can't sell a portion of a 12 pack, she sold 62 whole packages and had 2/3 of one remaining, 2/3 of 12 is 8 remaining.
I believe the answer is 1330
Answer:
z=1
Step-by-step explanation:
8(z+3)=32
Multiply 8 into the parenthesis.
8z+24=32
Subtract 24 both sides.
8z=8
Divide 8 both sides.
z=1
Answer: c = 520
Step-by-step explanation:
f(2) = 578 means that when x = 2, the value is equal to 578. We will plug these knowns in and then solve for c.
Given:
f(x) = 4x³ + 7x² - x + c
Substitute:
578 = 4(2)³ + 7(2)² - (2) + c
Distribute:
578 = 4 * 2³ + 7 * 2² - 2 + c
Raise to the power of 3 and 2:
578 = 4 * 8 + 7 * 4 - 2 + c
Multiply:
578 = 32 + 28 - 2 + c
Add:
578 = 60 - 2 + c
Subtract:
578 = 58 + c
Subtract 58 from both sides:
520 = c
Reflexive property:
c = 520
