Answer:
x = -42 is your answer
Step-by-step explanation:
x/6 = -7
Isolate the x. Note the equal sign, what you do to one side, you do to the other.
Multiply 6 to both sides
(x/6)(6) = (-7)(6)
x = (-7)(6)
Simplify. Multiply 6 with -7
x = (-7)(6)
x = -42

<u><em>Answer: x=-42 *The answer should be the negative sign.*</em></u>
Step-by-step explanation:
Multiplication property of equality is multiplying both sides of an equation by the same number does not change the equation.
x/6=-7
multiply by 6 both sides of an equation.
6x/6=6(-7)
simplify.
7*6=42
6*7=42
42/7=6
42/6=7
It changes to positive to negative.
x=-42

Answer:
23 more cubes
Step-by-step explanation:
If it's 2 times as long, the length is 2
If it's 3 times as wide, the width is 3
It it's 4 times as high, the height is 4
2 · 3 · 4 = 24, which is 23 more than 1
There's more than one way to combine them really
but an obvious one will be

Answer: -7.5
Step-by-step explanation:
area = 1/2bh.
area = 1/2(x+6)(5)
area = x/2 + 15
area = x/2 = -15
area = x = -7.5
area = -7.5
