Shawndra has $30 in her account and deposits $5 per week. Juan has $150 and withdraws $10 each week. After how many weeks will their balances be the
same?

Step-by-step explanation:

Shawndra y = 5x + 30

Juan: y = -10x + 150

-10x + 150 = 5x + 30

-15x + 150 = 30

-15x = -120

x = 8 weeks

b. x- 48 =120

step-by-step explanation:

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
