Add 4x to both sides and get
13 = 1 + 3x
12 = 3x [from subtracted 1 from both sides]
x = 4 [from dividing 3 from both sides]
therefore your answer would be x = 4
Ok so the first one is 225 miles but i can't do the graph
and i'm not great at math so give me a bit
Answer:
Step-by-step explanation:
Clue 1 :
"Percent of Decrease" = ( Final Number - Initial Number ) expressed as a percentage of the Initial Number
Clue 2 :
number X expressed as a percentage of Number Y = (X/Y) x 100 %
Good luck!
$90
because if 1 body equals 30 each and she has 3 body’s add 30 3 times 30+30=60+30=90
<span>Simplifying
10 + -3(3x + -40) = -9x
Reorder the terms:
10 + -3(-40 + 3x) = -9x
10 + (-40 * -3 + 3x * -3) = -9x
10 + (120 + -9x) = -9x
Combine like terms: 10 + 120 = 130
130 + -9x = -9x
Add '9x' to each side of the equation.
130 + -9x + 9x = -9x + 9x
Combine like terms: -9x + 9x = 0
130 + 0 = -9x + 9x
130 = -9x + 9x
Combine like terms: -9x + 9x = 0
130 = 0
Solving
130 = 0
Couldn't find a variable to solve for.
This equation is invalid, the left and right sides are not equal, therefore there is no solution.</span>
