N/2+4=-4. I need help I cannot figure this out and I left.my math binder at my school. :/ plz halp :3

Answers

Answer 1

Answer: $(n)/(2) +4=-4$

Multiply both sides by 2 :

$(n)/(2) *2+4*2=(-4)*2$

$n+8 =-8$

Subtract 8 from both sides:

$n+8-8=-8-8$

$n=-16$

hope this helps!

Answer 2

Answer: first subtract four from both sides and get n/2=-8. Then multiply both sides by 2 and get n=-16

9.9g of sugar is needed for every cake made. How much sugar is needed for 8 cakes?

Answers

Answer:

79.2 g of sugar is needed.

Step-by-step explanation:

9.9 times 8 is 79.2.

You can prove this by dividing 79.2 by 8 and you will get 9.9 as the answer.

Answer:

See answer below

Step-by-step explanation:

Hi there,

Get started by developing a relationship between the amount of sugar for 1 cake. We can use dimensional analysis to solve this.

$(9.9 \ g \ sugar)/(1 \ cake)$

Now, we know that we need 8 cakes. We put 1 cake on the bottom of the fraction so that it cancels out with the 8 cakes unit:

$(9.9 \ g \ sugar)/(1 \ cake)$ $* \ 8 \ cake = 9.9 g \ sugar * 8 = 79.2 g \ sugar$

a grocery store sells 6-pack of bottled water for $3.79 a 9 pack for $4.50 and a 12 pack for $6.89 which package costs the least per bottle? explain your reasoning

Answers

Find the unit price (price per bottle)
$3.79 ÷ 6 = $.63 a bottle (approximately)
$4.50 ÷ 9 = $.50
$6.89 ÷ 12 = $.57 (approximately)

So your best bet is the 9 pack.
You will find that sometimes your best value is not to buy the greatest amount of a product.

If c(x) = 4x – 2 and d(x) = x^2+ 5x, what is (c circle d) (x)?

Answers

Answer:

4x² + 20x - 2
