To simplify the given equation, you want to combine like terms. Since both terms have x^8, we can add the coefficients and leave the x^8
3x^8-7x^8 (do 3-7)
=-4x^8 so the answer is C

Hope this helps

Jarett's puppy weighed 3 3/4 ounces at birth at one week old, the puppy weighed 5 1/8 ounces at two weeks old the puppy weigh at
Mariulka [41]
Well, i find it helps to turn the fractions into decimals. 
3 3/4 = 3.75
5 1/8 = 5.125 

so now subtract: 
5.125 - 3.75 = 1.375 

so that means it weighs 1.375 ounces more each week

so then take the second week (5.125) and add on 1.375

5.125 + 1.375 = 6.5 

now to convert that into a fraction (lowest terms) it would be: 
6 1/5 ounces 

Therefore, 
Jarett's puppy will weigh 6 1/5 ounces at three weeks old. 

Hope this helps and ave a great day! :D

First, you need to find out the perimeter of the fence and how much of the fence he had around his garden last year (leftovers) and subtract them I think.

Solve for y a(n+y)=10y+32 what is the answer
Solnce55 [7]
A (n + y) = 10y + 32
(an + ay) = 10y + 32

an + ay = 32 + 10y

Solve for "a"
-32 + an + ay + (-10y) = 32 + 10y + (-32) + (-10y)
-32 + an + ay + -10y = 32 + -32 + 10y + -10y
<span>- 32 + an + ay + (-10y) = 0 + 10y + (-10y) 
- 32 + an + ay + (-10y) = 10y + (-10y)

</span><span>10y + -10y = 0
-32 + an + ay + (-10y) = 0

Thi could not be determined. (no solution)</span>

Make the 0.8 a whole number.- 8

8 divided by 16= 2

Each person will get 2 pounds of turkey.
