B. is the correct answer as 387 contains 80 and 8 * 10 = 80. I hope this helps!!
Children=4
Notebooks=60
It said mama's got an amount of books, so you can transform this into a equation
X=children
Notebooks= 13x +8
Notebooks= 15x
Now you just establish a system of equations, thus notebooks=notebooks
13x + 8= 15x
2x=8
X= 4
1. Her constant speed was(4,800)
A cube shaped box of side length equal to m foot has volume
foot cubed.
a.
Let v1 be the volume of the box with side length 1 ft.
and v2 be the volume of the box with side length x ft.
(foot cubed)
(foot cubed)
Vtotal=
feet cubed
b.
by the "sum of cubes" identity:
,
this identity can be derived by dividing
by (x+1), by long division.
c. Vtotal when x=3 feet is:
Vtotal=
(feet cubed)
Answer:
Contradiction equation or no solution
Step-by-step explanation:
10 + 6 • -2 = 4 • 2 + 6
10 - 12 = 8 + 6
-2 = 14
This is a contradiction statement
