Hey there!

Answer:\boxed{x=-9}

Explanation:

2x+20=-3x-25

2x+20+3x=-3x-25+3x\\5x+20=-25 Add 3x to both sides

5x+20-20=-25-20\\5x=-45 Subtract 20 to both sides

\frac{5x}{5}=\frac{-45}{5} Divide both sides by 5

x=-9

Hope this helps!

The driver of the bus filled the gas tank with gas by putting in 21 gallon. If the gas gauge was at five-eighths before she fill
vazorg [7]

Answer:

56 gallons

Step-by-step explanation:

When her gas tank is full, she has x gallons in the tank.

when she went to the gas station, she had (5/8) of x gallons of gas in her tank. she added 21 gallons into her tank, then she had x gallons in her tank.

(5/8)x + 21 = x

subtract x and 21 from both sides

(5/8)x - x = -21

factor out an x from the left side

x(5/8 - 1) = -21

simplify the parenthesis

x(-3/8) = -21

multiply both sides by -8/3

x= 56 gallons

Choose the expression that is equal to 28.3
tamaranim1 [39]
The first one = 60.3 so it can’t be that one.
the second one = 34.5 so not that one either
the third one = 60.3
and the last one = 28.3

What is 5/6-1/8 equal
4vir4ik [10]

Sorry if I'm wrong - This is how I learned to subtract fractions in the 7th grade

First, I would line up the fractions side-by-side:

5/6      1/8

Then, my teacher would tell me to look at the numerators and subtract those - The answer would be 4

Next, she would say to do the same to the denominators - The answer is 2

4/2 is your answer I believe

Hope this helped! :)
