Directions: Choose the letter of the correct answer. Solve the system of equation y=4x-5 and y=3x
A. y=10, x=13
B. y=5, x=15
C. y=7, x=6

Solve the system of
equation -4x+5y=35 and y=3x
A. X-15 y=19
B. x-14 y=11
C. x=45 y=12

Step-by-step explanation:

1) y = 3x (I)

  y = 4x  - 5 (II)

Plug in y= 3x in equation (II)

3x  =  4x - 5

3x + 5 = 4x

       5 = 4x - 3x

      5 = x

x= 5

Plug in s = 5 in equation (I)

y = 3*5 = 15

x = 5

y = 15

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.

tube or goog would be a great resource to with that question
