Because both lines are parallel, if you add the 5x+5 to the 115 those would equal 180 degrees
so you have 5x+5 + 115 = 180
combine like terms:
5x + 120 = 180
subtract 120 from both sides
5x = 60
x = 60/5
x = 12
Answer:
18
Step-by-step explanation:
There are 18 girls on the team this year.
If you take 20 and divide the number by 10 you will get 2.
10%=2
If you multiply 2x10 you get 20.
20-2=18
Answer:
$60
Step-by-step explanation:
We can create a proportion to find the markup from original price to the marked up price. A proportion is an equation where two ratios are set equal to each other. We create two fractions using the prices and percents. It is marked up by 20% so we pay 120% of $50.
![\frac{120}{100} =\frac{x}{50}](https://tex.z-dn.net/?f=%5Cfrac%7B120%7D%7B100%7D%20%3D%5Cfrac%7Bx%7D%7B50%7D)
We begin solving by cross multiplying numerator to denominator of each fraction.
![120(50)=100(x)\\6000=100x\\\frac{6000}{100}=\frac{100x}{100} \\60=x](https://tex.z-dn.net/?f=120%2850%29%3D100%28x%29%5C%5C6000%3D100x%5C%5C%5Cfrac%7B6000%7D%7B100%7D%3D%5Cfrac%7B100x%7D%7B100%7D%20%20%5C%5C60%3Dx)

Step-by-step explanation:
Answer:
36mm
Step-by-step explanation:
Ok so, here is what you do the 10mm and the 4mm you subtract them to get 6 then you will use 6 for the base of the triangle since, when we subtracted we got the rest for the bottom base of the triangle. Then we do 6 times 12 and we get 72. We divide 72 divided by 2 and get 36 and that is your answer 36mm.
