Answer:
x=0
Step-by-step explanation:
<u>Key skills needed: Proportions, Cross multiplication, One variable Equations, Multiplication</u>
1) Since this is a proportion, we need to cross multiply. A proportion is just 2 fractions equal to each other in this format.
---> Cross multiplication is when you multiply the first fraction's numerator by the second fraction's denominator, and you multiply the first fraction's denominator by the second fraction's numerator.
---> You set these products equal to each other.
2) So if we cross multiply it would be: 3(3x+5) = 5(3-2x)
---> If you multiply everything out, it would be --> 9x + 15 = 15 - 10x
3) Move the x terms to one side and the numbers to the other side
---> 9x + 10x = 15-15
4) Combine like terms (9x+ 10x= 19x) (15-15=0) 19x = 0
5) Divide by 19 and x=0.

Answer:
x = 88
Step-by-step explanation:
x + 48 + (x - 44) = 180 (inside of a triangle is equal to 180 degrees)
2x + 4 = 180
2x = 176
x = 88
Let's have time in minutes as x.
Now we will make the next equation
3x+126 = 2x+151 First we will add number (-126) to the both sides and get
3x+126-126=2x+151-126 => 3x= 2x + 25
3x=2x+25 Now we will add monom (-2x) to the both sides and get
3x-2x=2x-2x+25 => x=25 minutes
They spent the same time 25 minutes and earned the same amount of money
Wilson earned 3*25+126= 75+126= $201
Jonathan earned 2*25+151=50+151= $201
Good luck!!!
