Solve for x: 2x + 13 = 8x - 41
kherson [118]

Answer:

9 is your answer for x.

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. Do the opposite of PEMDAS.

PEMDAS is the order of operations, & =

Parenthesis

Exponent (& Roots)

Multiplication

Division

Addition

Subtraction

First, subtract 13 & 8x from both sides:

2x (-8x) + 13 (-13) = 8x (-8x) - 41 (-13)

2x - 8x = -41 - 13

Simplify. Combine like terms:

-6x = -54

Isolate the variable, x. Divide -6 from both sides:

(-6x)/-6 = (-54)/-6

x = (-54)/(-6)

x = 9

x = 9 is your answer.

PLEASE HELP if Suzy can drive 4/5 miles in a half hour how many miles can she drive in 1 hour FOR A TEST PLEASE ANSWER
kati45 [8]
Since you are trying to figure out how many miles she can drive in 1 hour and you already have half of that hour, all you would need to do is double that number. 
\frac{4}{5} × \frac{2}{1}= \frac{8}{5}

Now, all you would need to do is simplify the answer.
\frac{8}{5} = 1 \frac{3}{5} or 1.6

The answer would be, Suzy can drive 1 \frac{3}{5} or 1.6 miles in 1 hour. 

I hope this helps!
