Answer:
C.
Step-by-step explanation:
Looks like C ( if the polynomial in the question contains x6 NOT x).
Baby hippo’s current born weights is 2200. Adult hippos can weight up to 5300 pounds. To find how much more the baby hippo can gain, subtract bith numbers.
W=2200-5300.
Let b equal the speed of the boat in still water.
Let c equal the speed of the current.
Going downstream, we can write the equation:

which can be rearranged to:
3b + 3c = 120 ............(1)
Going upstream, we can write the equation:

which can be rearranged to:
4b - 4c = 120 .............(2)
Multiplying equation (1) by 4, and multiplying equation (2) by 3 we get:
12b + 12c = 480 ........(3)
12b - 12c = 360 .........(4)
Adding equations (3) and (4) results in the following equation:
24b = 840
Answer:
Sabrina bought 3 pounds of bananas.
Step-by-step explanation:
Given equations are:
a + b = 8 Eqn 1
0.95a + 1.10b = 8.05 Eqn 2
As we have to find the number of pounds of bananas bought, we will eliminate the variable a from the equation.
Multiplying Eqn 1 by 0.95
0.95(a+b=8)
0.95a+0.95b=7.60 Eqn 3
Subtracting Eqn 3 from Eqn 2
(0.95a+1.10b)-(0.95a+0.95b)=8.05-7.60
0.95a+1.10b-0.95a-0.95b=0.45
0.15b = 0.45
Dividing both sides by 0.15

Hence,
Sabrina bought 3 pounds of bananas.
