50 - x

This is because you are looking for the amount of money he spent to find how much he has left.
In order to do this, you need to subtract x, the amount he spent, from the total, 50, in order to get how much money he has left.

Hope this helps!

Two angles form a linear pair the Measure of one angle is 2.6 times the measure of the other angle find the measure of each angl

Sedaia [141]

Answer:

The measures of the angles are 50° and 130°

Step-by-step explanation:

Let

x ----> the measure of one angle

y ----> the measure of the other angle

we know that

If two angles form a linear pair , then their sum is equal to 180 degrees

$x+y=180$ -----> equation A

$x=2.6y$ ----> equation B

substitute equation B in equation A

$2.6y+y=180$

solve for y

$3.6y=180$

$y=50^o$

Find the value of x

$x=2.6(50)=130^o$

The measures of the angles are 50° and 130°

Show how to solve -5y+8=-3y+10

marta [7]

-5y+8=-3y+10
-5y+3y=10-8
-2y=2
-2y/-2=2/-2
y=-1

I grouped the alike variable to one side, and the number to the other side, added and subtracted it, divided both sides by -2, and got -1
