4 0

Step-by-step explanation:

Use substitution to solve the system.

y = 2x+8______equation1

-3x+2y = 13______equation2

sub y into equation 2

-3x+2(2x+8)=13

-3x+4x+16=13

x+16=13

x=13-16

x=-3

sub X into equation 1

y=2x+8

y=2(-3)+8

y= -6+8

y=2

x= -3 y=2

kaheart [24]

Answer: 12

Step-by-step explanation:

Given: A florist has 60 tulips and 72 daffodils.

He wants to make bouquets with the same number of tulips and the same number of daffodils in each using all the flowers.

Then, the greatest number of bouquets the florist can make =  GCD (60,72)

where GCD = Greatest Common Divisor

Prime factorization of 60 and 72 :

60 = 2 x 2 x 3 x 5

72 = 2 x 2 x 2 x 3 x 3

GCD(60,72) = 2 x 2 x 3 = 12

Hence, the greatest number of bouquets the florist can make = 12

Zinaida [17]
H + c = 605
c = h + 55

h + h + 55 = 605
2h + 55 = 605
2h = 605 - 55
2h = 550
h = 550/2
h = 275 <== there were 275 hamburgers sold on Friday

c = h + 55
c = 275 + 55
C = 330...there were 330 cheeseburgers sold on Friday
