Method of substitution a+3b=5 and 7a-8b=6

b=1, a=2

Step-by-step explanation: a=5-3b, so plug (5-3b) into a for the second equation for 7(5-3b)-8b=6 so 35-29b=6 so 29=29b so b=1, then plug b=1 into any equation to solve for a, so a+3(1)=5, so a=2. Hope this helps!

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

too many. (jk)

31 v bucks
