Answer:
x=2
Step-by-step explanation:
18-2x+10=12x
-2x+18+10=12x
-2x+28=12x
subtract 28 from both sides= -2x=12x-28
subtract 12x from both sides= -14x=-28
divide both sides by -14= x=2
x=2 is your final answer
Answer
-4
Step-by-step explanation:
x^0 = 1
so -4x^0
= -4
Answer:
418cm2
Step-by-step explanation:
Separate the figure into a square and a triangle. Find the area of each and add.
s2 = area of square
192 = 361 cm
bh = area of triangle
(6)(19) = 57 cm2
361 + 57 = 418 cm2
Let n = the unknown number
"The product of a number and 4" = 4 * n = 4n
"increased by 16" = + 16
Set it all equal to - 2.
4n + 16 = - 2
Subtract 16 from both sides to get constants on one side and variables on the other.
4n = - 2 - 16
Combine like terms:
4n = - 18
Divide both sides by 4 to isolate variable n.
n = - 18 / 4
= - 4 and 2/4 = - 4 and 1/2
