Find the solution to the following system using substitution or
elimination:
y = 2x - 1
y = 5x - 7
of 5
(-2,-5)
(2,3)
( 6/7,5/7)
(1,1)

(2,3)

Step-by-step explanation:

Substitute y = 2x - 1 in the equation y = 5x - 7

2x - 1 = 5x - 7

2x  - 1 + 7 = 5x

2x + 6 = 5x

6 = 5x - 2x

6 = 3x

3x = 6

x = 6/3

x = 2

Substitute the value of x in, y = 2x - 1

y = 2*2 - 1

y= 4 - 1

y = 3

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
