The linear equation shown below expresses the revenue of a café based on the number of children and adults who ate there last tuesday. 10x + 15y = 180 x = number of children y = number of adults if 10 adults ate at the café that day, how many children also ate there?

3 children ate there.

Step-by-step explanation:

Given linear equation that shows the  revenue of a café based on the number of children and adults who ate,

10x + 15y = 180  

Where, x represents number of children,

y represents number of adults,

If y = 10,

Then from the above equation,

10x + 15(10) = 180

10x = 180 - 150 = 30

x = 3

Hence, 3 children ate there.

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.

a. (14,375+570)(5.3) b. 158,417$

step-by-step explanation:

a. you are basically just setting up the equation. f= amount of debt hence 14,375. g= how much she is borrowing from her parents weekly hence 570 and t= the interest on her debt. creating the equation.

b.   14,375+570= 14,945

      14,945 x 5.3 = 79,208.5

      79,208.5 x 2(years) = 158,417(answer)
