Answer:

F = 110°

I'm not sure, but since no one answered, here it goes...

Step-by-step explanation:

∵ FD = FE (Given in Diagram)

∴ ΔDFE is isosceles , ∴m∠E = m∠D

1 ) 3x + 14 = 5x

14 = 5x - 3x

14 = 2x

14 / 2 = x

7 = x

m∠E = 3*7 + 14 = 35°

m∠D = 5*7 = 35°

m∠F = 180 - (35+35)

m∠F = 110°

You have $80. Jeans costs $29 and shirts $12. Mom told you to buy one pair of jeans and use the rest of the money to buy shirts.

SIZIF [17.4K]

You can buy 4 shirts because you bought one pair of jean (80 - 29 = 51) and so with the leftover money you could buy 4 shirts because (12 x 4 = 48) and then you'd have a leftover 3 dollars.

8x = 2y + 5 3x = y + 7 Solve the system of equations by substitution.

jasenka [17]

3x = y + 7
 y =3x-7

8x = 2y + 5
8x = 2(3x-7) + 5
8x=6x-14+5
8x-6x=-9
2x=-9
x=-4.5

8x = 2y + 5
8(4.5)=2y+5
36=2y+5
2y=31
y=15.5
