Answer:

a=2

Step-by-step explanation:

8a +9=3a +19

Subtract 9 from both sides

-9=      -9

8a=3a +10

Subtract -3a from both sides

5a=10

5a=10

5a divided by both sides

5/5

10/5=2

a=2

Answer:

x = 81

Step-by-step explanation:

y = k√x

56 = k√49

56 = k(7)

Divide both sides by 7

8 = k

k = 8

------------------------

When y = 72

72 = 8√x

Divide both sides by 8

9 = √x

Square both sides

81 = x

x = 81

Step-by-step explanation:

From the above question:

If:

80 miles = 4 gallons of gas

100 miles = x gallons of gas

Cross Multiply

80 × x = 100 × 4

x = 100 × 4/80

x = 5 gallons of gas

Therefore, Jackson would use 5 gallons of gas to get to Mount Highmore.

Gnesinka [82]

Answer: 2/3x-y=19/3

Step-by-step explanation:

Points are useless since we already know the point slope form and we can just simply that

y+1=2/3(x-8)

y+1=2/3x-16/3

y=2/3x-19/3

2/3x-y=19/3
