The answer would be A/ x+y.
First you would need to place the x+y into parenthesis with the z on the outside of the parenthesis in which would be z(x+y)=A. Then you would divide both sides by x+y. This would leave you with z= A/x+y

If you know a point on a line and you know the equation of a line parallel to this line, explain how to write the line’s equatio
vesna_86 [32]

Answer:

Step-by-step explanation:

First, parallel lines have the same slope, so the slopes should be the same , and then you use the given point to find the y intercept

EX:

y=x+1

find equation of line the is parallel and passes through (1, 1)

Same slope, so y=x+b

then plug in the point

1=1+b

b=0

our line would be y=x

Please find the value of x
Margarita [4]

Answer:

x=5

Step-by-step explanation:

The sum of the angles of a triangle are 180 degrees

The box is a right angle which is 90 degrees

60+6x+90 = 180

Combine like terms

150+6x= 180

Subtract 150 from each side

150-150+6x = 180-150

6x = 30

Divide by 6

6x/6 =30/6

x = 5
