Answer:
B
Step-by-step explanation:
The cube of twice a number =

Decreased by 11 =

Hence, the cube of twice a number decreased by 11 =

1/8 of 32 is 4 so if Ryan is 4 then Brandon is 2
so Ryan = 4 and Brandon = 2
7/8, One should first make all the fractions have the same denominator so 3/8 and 1/2=4/8 so then add 3/8+4/8=7/8
Answer:
(1, -6)
Step-by-step explanation:
the layout of your question is kind of confusing, but i'm guessing this is the system of equations
x = -y - 5
-3x + 7y = -45
plug in x to the second equation
-3(-y - 5) + 7y = -45
distribute
3y + 15 + 7y = -45
combine like terms
10y = - 60
divide by 10
y = -6
plug y into first equation
x = -(-6) - 5
x = 6 - 5
x = 1
The answer I believe is 10 calories per minute because 20 x30 =600 I did that because she burned 20 calories per minute so with that being said there’s 60 minutes is the maximum minutes any time can go to so you do 600 divided by 60 which equals 10 which means she burns 10 calories per minute hope this is right
