Examine this system of equations. which numbers can be multiplied by each equation so that when the two equations are added together, the y term is eliminated?

18 times the first equation and 8 times the second equation

Step-by-step explanation:

we have

------> first equation

------> second equation

step 1

Multiply the second equation  by 8 both sides to remove the fraction in the variable y

step 2

Multiply the first equation  by 18 both sides to obtain the coefficient -3 in the variable y

step 3

Adds the new equation 1 and equation 2

The y-term is eliminated

therefore

The answer is

18 times the first equation and 8 times the second equation

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
