Answer:

x = -20

Step-by-step explanation:

- 2.5x - 10 = 40

Collect like terms and simplify

- 2.5x = 40 + 10 \\  - 2.5x = 50

Divide both sides of the equation by -2.5

\frac{ - 2.5x}{ - 2.5}  =  \frac{50}{ - 2.5}

Simplify

x =  - 20

What is the midpoint coordinates of segment HX H(13,8) X(-6,-6)
Setler79 [48]
Midpoint of (x1,y1) and (x2,y2) is

(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})

so the midpoint of HX is the mdpoint of (13,8) and (-6,-6)
which is

(\frac{13-6}{2},\frac{8-6}{2}=
(\frac{7}{2},\frac{2}{2}=
(3.5,1)

the midpoint is (3.5,1)

Can someone help me with E please I don’t know what operation to use
gtnhenbr [62]
The first question asks who sold more rolls. So start with figuring out how many Christie sold.
5 total - 1 2/3 left = 3 1/3 sold
you can convert the numbers to improper fractions with the same denominator. Like this:
5 x (3/3) - (3+2)/3
15/3 - 5/3 = 10/3
10/3 = 3 1/3

So now we know Christie sold more because 3 1/3 dozen is more than 2 1/2 dozen.

The part asks how many more.. Subtract the amounts the two girls sold.

3 1/3 - 2 1/2
10/3 x (2/2) - 5/2 x (3/3)
20/6 - 15/6 = 5/6

Christie sold 5/6 dozen more rolls. A dozen is 12 rolls so if you wanted to go further you just multiply 12 x 5/6 = 10 rolls
