1. what equation represents the following word sentence?
the quotient of a number b and 0.3 equals negative 10
i think it's b/0.3 = -10
2. which equation is equivalent to the following equation?
-3/4x + 1/8 = -3/8
a. -3/4x = -3/8 - 1/8
b. -3/4x = -3/8 + 1/8
c. x + 1/8 = -3/8 * (-4/3)
d. x + 1/8 = -3/8 * (-3/4)
i think it's b

Answer 1

3. a student was solving the following equation:
-96 = -6(x - 15)
-96 = -6x - 90
-96 + 90 = -6x - 90 + 90
-6 = -6x
-6/-6 = -6x/-6x
1 = x
what should they do to correct the error that they made?
a. first add 6 to both sides
b. first subtract x from both sides
c. distribute the -6 to get 6x - 90
d. distribute the -6 to get -6x + 90
i think it's c

Answer 2

write an expression in simplest form that represents the perimeter of the polygon.
the measure of the sides are 3x, x + 10, 2x + 2, and 5x.
would the simplified expression be 11x + 12?

Answer 3

Number one looks good.
For number two i would say A because if you take a negative to the other side of an equal sign it will be positive.
Well for number three i think it's D because when you open -6(x-15) that is equal to -6x+90.
