LOQP and ZPQR are complementary.
The two angles are equal. Which equation
can be used to find the measure of each
angle?
A. 2 + a = 90
B. 2a = 90
C. 2 + a = 180
D. 2a = 180

answer:

A: 6x − 3y = −4

B: −4x − y = 5

To solve this system of equations by elimination, what could you multiply each equation by to cancel out the y-variable?

Step-by-step explanation:

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

step-by-step explanation:

mean or average is 40.6
