So you know the whole line is XZ which is 83.Then you find out it is in two parts so that is XY and YZ which are 11 and 4c. You can make the equation:
11+4c=83
4c=72
c=18
c=18 and YZ=72
Answer:
![\frac{x-16.5}{16.5}=0.30](https://tex.z-dn.net/?f=%5Cfrac%7Bx-16.5%7D%7B16.5%7D%3D0.30)
Hopefully, this is your desired setup. (I noticed the formula you have to fill in there.)
Have a good day.
Step-by-step explanation:
Hi.
You could use the percent change formula.
Since we know it is a percent increase then we will do new-old instead of old-new:
![\frac{\text{new}-\text{old}}{\old}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7Bnew%7D-%5Ctext%7Bold%7D%7D%7B%5Cold%7D)
x is the new amount of shampoo.
16.5 is the original amount (old) of shampoo.
The percent increase is 30%=0.30 .
So we have the following equation:
![\frac{x-16.5}{16.5}=0.30](https://tex.z-dn.net/?f=%5Cfrac%7Bx-16.5%7D%7B16.5%7D%3D0.30)
We could have found the equation like this:
![16.5+16.5(0.30)=x](https://tex.z-dn.net/?f=16.5%2B16.5%280.30%29%3Dx)
Subtract 16.5 on both sides:
![16.5(0.30)=x-16.5](https://tex.z-dn.net/?f=16.5%280.30%29%3Dx-16.5)
Divide both sides by 16.5:
![0.30=\frac{x-16.5}{16.5}](https://tex.z-dn.net/?f=0.30%3D%5Cfrac%7Bx-16.5%7D%7B16.5%7D)
By us of symmetric property of equality:
![\frac{x-16.5}{16.5}=0.30](https://tex.z-dn.net/?f=%5Cfrac%7Bx-16.5%7D%7B16.5%7D%3D0.30)
First, you can add up 4+2 to get 6 because they’re both rates.
Next, divide 18 by 6 and you get 3.
So, it will take three hours for the boys to meet up.
One way to check your answer is to multiply 4x3=12 and 2x3=6 and 12+6 is 18.
Answer:
c = 26 cm
Step-by-step explanation:
using the Pythagorean theorem:
10² + 24² = c²
c² = 100 + 576 = 676
c = 26 cm
