What is the value of x?<br><br><br><br> Enter your answer in the box.<br><br><br> _____ units
krek1111 [17]

Answer:

x=28

Step-by-step explanation:

We can use similar triangles and proportions to solve this problem.  Put the side of the small triangle over the same side of the larger triangle.

x               42

---------- = ----------

x+10           42+15

Simplify

x               42

---------- = ----------

x+10           57

Using cross products

57x = 42 (x+10)

Distribute

57x = 42x+420

Subtract 42x from each side

57x-42x = 42x-42x +420

15x = 420

Divide each side by 15

15x/15 = 420/15

x=28

What is x/13-5=25/26
Juliette [100K]

\frac{x}{13} -5=\frac{25}{26}    Add 5 on both sides

\frac{x}{13}=\frac{25}{26}+5    Make the denominators the same

\frac{x}{13}=\frac{25}{26}+\frac{130}{26}

\frac{x}{13}=\frac{155}{26}    Multiply 13 on both sides

(13)\frac{x}{13}=(13)\frac{155}{26}

x=\frac{2015}{26}

x=\frac{155}{2}
