you subtract the powers when dividing
therefore 7-(-4)
=7+4
=11
=x^11
Answer:
<h2>C.</h2>
Step-by-step explanation:
Look at the pictures.
x - sausage
y - bacon
A. 20 pounds of sausage and 90 pound of bacon
x = 20 → y = 100 > 90
B. 40 pound of sausage and 40 pound of bacon
x = 40 → y = 75 > 40
C. 60 pound of sausage and 80 pound of bacon
x = 60 → y = 50 < 80
D. 80 pound of sausage and 20 pound of bacon
x = 80 → y = 25 > 20
Volume = base area x height.
Required amount of water = volume of tank - amount of water currently in the tank. = (45 x 25) - (45 x 12) = 45(25 - 12) = 45 x 13 = 598 cm^3
Answer:
3x-9=2x+4
-2x -2x
x - 9 = 4
+ 9 +9
<h2>
x = 13</h2>
First isolate the variable into one side.
Then simplify like terms.
Hope this helps.
