Just substitute x = 2 and y = 5 into the equation wherever you see x and y.

2 + (12 - 5x) · 2y

2 + (12 - 5(2)) · 2(5)

2 + (2) · 10

4 · 10

40, is the answer which should be the first box.

What is the measurement of x in the equation. 8x+5x+2x-11+6=180
34kurt

Answer:

x = 37/3 = 12.333

Step-by-step explanation:

Step  1  :

Pulling out like terms :

1.1     Pull out like factors :

  15x - 185  =   5 • (3x - 37)

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

2.1      Solve :    5   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2      Solve  :    3x-37 = 0

Add  37  to both sides of the equation :

                     3x = 37

Divide both sides of the equation by 3:

                    x = 37/3 = 12.333

Which segment of the triangle will give you the height of your peak? Write the equation for the proportion that will allow you t
Novosadov [1.4K]
The segment that will give the height of the peak is the segment that is located from the right angle to the peak.
 To find the height, we can use the fact that we have two similar triangles.
 We are going to define a variable.
 We have:
 x: height of the peak.
 For similar triangles, we have the following relationship:
 \frac{x}{20} = \frac{6}{3}
 From here, we clear the height of the peak
 Answer:
 
the equation for the proportion that will allow you to find the height of your peak is:
 
\frac{x}{20} = \frac{6}{3}
