Answer:
11 hours
Step-by-step explanation:
let he works at first store x hours and at car wash y hours. Then
x+y=25
multiply by 4
4x+4y=100 ...(1)
12x+15y=333
divide by 3
4x+5y=111 ... (2)
(2)-(1) gives
y=111-100=11
(b) because when you change 215% into a decimal it’s 2.15 then multiply that by 50 you get 170.5 and you move the decimal to get 1.705 so it’s b
Answer:
y=-2/3x+9
Step-by-step explanation:
Use point-slope formula:
y-y1 = m(x-x1)
y-5=-2/3(x-6)
y-5=-2/3x+4
y=-2/3x+9
You would then proceed to graphing this equation, as it is in slope intercept form now.
