Answer:
<h2><u><em>
x = -7</em></u></h2>
Step-by-step explanation:
_3x_13 =_7x+15 what is the anSWER?
assuming that the underscore is a minus and you are looking for the x value.
-3x - 13 = -7 + 15
-3x = -7 + 15 + 13
-3x = 8 + 13
-3x = 21
x = -7
---------------
check
-3 * (-7) - 13 = -7 + 15
21 - 13 = 8
8 = 8
<u><em>the answer is good</em></u>
Answer:
14 students
Step-by-step explanation:
Its simple, you just divide 112 by 8.
Blue = 6x3 = 18
Purple = 4 + (5 x 2) = 14
Orange = 2(2 x 3) = 12
Bottom = 6 x 3 = 18
Back = 4 x 3 = 12
Opposite purple = purple = 14
18 + 14 + 12 + 18 + 12 + 14 = 88
Answer = 88 cm squared

Answer:
x = 22/25
Step-by-step explanation:
Given
2 1/5 x
---------- = -----------
10 4
Using cross products
2 1/5 * 4 = x*10
Change 2 1/5 to an improper fraction
2 1/5 =(5*2+1)/5 = 11/5
11/5 *4 = 10x
44/5 =10x
Multiply each side by 1/10 to isolate x
44/5 *1/10 = 10x * 1/10
44/50 = x
Divide top and bottom by 2
22/25 = x
