The measure of two complementary angles are represented by x+5 and 4x - 15 find the value of x

Answers

Based on the calculations, the value of x will be equal to 20°

First and foremost, we should note that the total angles in a complementary angles equal to 90°.

In this case, we have to add the two angles that we are give and then equate them to 90°. This will be:

(x + 5°) + (4x - 15°) = 90°

x + 5° + 4x - 15° = 90°

Collect like terms

x + 4x = 90° - 5° + 15°

5x = 100°

x = 100°/5

x = 20°

Therefore, based on the calculations, the value of x is 20°

complementry angles sum up to 90.
so, (x+5)+(4x-15)=90
x+4x+5-15=90
5x-10=90
5x=90+10
x=100/5
x=20

Muriel says she has written a system of two linear equationsat has an infinite number of solutions One of the equationsof the system is 3y 2x 9. Which could be the otherequation?

Answers

The equation of the line is
3y = 2x - 9

For the system to have infinite number of solutions, the equations of the lines must be equivalent i.e., the equations will result to the same equation if the coefficient of one variable in an equation is made equal to the coefficient of the same variable to the other equation. So,

The possible answers are
y = 2/3 x - 3
3/2 y = x - 9/2

Or any multiples or rearrangements of either equations.

Answer:

y=2/3x-3
