1 The expression $1.75 + $0.15x can be used to find Mr. Thompson's cost for
making x dozen cookies. How much does it cost Mr. Thompson to make 25
dozen cookies? {Write an equation.} *and also ( solve and equation).

Step-by-step explanation:

3x - 4y = 13 (1)

2x + y = 5 (2)

——————

3x - 4y = 13

4(2x + y = 5) (2) times 4

——————-

3x - 4y = 13

8x + 4y = 20

——————-

11x = 33

x = 33/11

x = 3

Plug x = 3 in (2):

2(3) + y = 5

6 + y = 5

y = 5-6

y = -1

Thus, x = 3 and y = -1

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm

the answer is 5/14.

hope this .
