Solution:
Consider the following expression:
2.5 x 8(20+5)
Solving the expression inside the parentheses first, we obtain:
2.5 x 8(25)
this is equivalent to:
2.5 x 200
this is equivalent to:
500
so that, we can conclude that the correct answer is:
500
Answer:
(-4, -5)
Step-by-step explanation:
-4x + 2y = 6
-4x + 2(x - 1) = 6
-4x + 2x - 2 = 6
-2x - 2 = 6
-2x - 2 + 2 = 6 + 2
-2x = 8
-2x/-2 = 8/-2
x = -4
------------------------
y = x - 1
y = -4 - 1
y = -5
-------------------------
-4(-4) + 2(-5) = 6
16 + -10 = 6
6 = 6
Answer:
54
Step-by-step explanation:
Since it's a "cube", all sides must be equal. Therefore, the length of one side is equal to the cube root of the volume.
3√27=3
An area of one surface is equal to
3²=9
Since the area of all surfaces are equal, we can assume that the surface area of this cube is
9⋅6
, because there are 6 surfaces on a cube
9⋅6=54
Hope this helps.
It's the distributive property of multiplication over addition and/or subtraction
Answer:
m = 4
Step-by-step explanation:
9/6=6/m
9m = 36
m = 4
