HELP PLEASE I NEED HELp
lidiya [134]

Answer:

Step-by-step explanation:

GH bisects ∠FGI

∠HGI = ∠HGF

4x - 14 = 3x - 3

4x = 3x - 3 + 14    {Add 14 to both sides}

4x = 3x + 11             {Subtract 3x from both sides}

4x - 3x = 11

x = 11

∠HGI = 4x - 14

         = 4*11 - 14

         = 44 - 14

         = 30°

∠FGI = 30 + 30

        = 60°

Geri spent Friday, Saturday and Sunday selling a total of 24 magazines orders for her school.The amounts on those 3 days were co
ryzh [129]

The sale on Friday = x = 6

The sale on Saturday = x+2 = 6 + 2 =8

The sale on Sunday = x+4 = 6+4 =10

Step-by-step explanation:

Let x be the sale of Friday

Then

x+2 will be the sale of Saturday

x+4 will be the sale of Sunday

According to the given statement, that the total sales were 24

x+(x+2)+(x+4) = 24\\x+x+2+x+4 = 24\\3x+6 = 24\\Subtracting\ 6\ from\ both\ sides\\3x+6-6=24-6\\3x=18\\Dividing\ both\ sides\ by\ 3\\\frac{3x}{3} = \frac{18}{6}\\x=6

The sale on Friday = x = 6

The sale on Saturday = x+2 = 6 + 2 =8

The sale on Sunday = x+4 = 6+4 =10
