Step-by-step explanation:

let price of  one pretzel=x

price of one soda=y

3x+4y=11.25   ...(1)

5x+2y=8.25    ...(2)

multiply by 2

10x+4y=16.50   ...(3)

(3)-(1) gives

7x=5.25

x=0.75

from (1)

3(0.75)+4y=11.25

2.25+4y=11.25

4y=11.25-2.25

4y=9

y=9/4=2.25

cost of one pretzel=$0.75

cost of one soda=$2.25

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.

interior paint coverage depends on the brand of paint used. the coverage amount is listed on the label of the paint can. use this to adjust the values in the paint coverage section below. paint usually is applied at 350 to 400 square feet per gallon (primer at 200 to 300 square feet per gallon).
