Point H is between G and I. If HG = 8x + 7, HI = 3x - 2, and GI = 38, what would be the length of GH ?
AVprozaik [17]

Answer:

let's see what to do...

Step-by-step explanation:

H is between G and I.

G I = G H + H I

38 = 8 x + 7 + 3x - 2

38 = 11 x + 5

subtract the sides of equation minus 5

38 - 5 = 11 x + 5 - 5

33 = 11 x

divided the sides of equation by 11

33 ÷ 11 = 11 x ÷ 11

3 = x

So the lenght of (G H) is :

8 x + 7 -----¢ 8 (3) + 7 = 24 + 7 = 31

And we're done.

Thanks for watching buddy good luck.

CaHeK987 [17]

Answer: 18

Step-by-step explanation:

Let x be the number of 2 point baskets made and y be the number of 3 point baskets made

:

1) x + y = 26

:

2) 2x + 3y = 60

:

solve equation 1 for x and substitute in equation 2

:

x = 26 - y

:

2(26 - y) +3y = 60

:

52 -2y +3y = 60

:

y = 8

:

x = 26 - 8 = 18

:

******************************

The team made 18 2-point shots
