Step-by-step explanation:
y + 4 = -2x + 2
2x + y = -2
2x = -2 - y
x = -2 -y/2
Answer:
900
Step-by-step explanation:
Because the unit rate of mins per mile is 7.5 min for each mile. So, then you multiply 120 with 7.5 and move the decimal place to get
Answer:
Step-by-step explanation:
reading_rate: 2.5R = 1250
R = 1250/2.5 = 500 pages/hr or ( 1 hr)/(500 pages)
Solve for hr?
=( 1 hr)/(500 pages) * 1250 pages
now, cancel out pages and we are left with hours
= 1250/500 hours
= 2.5 hours
Answer:
1. x + y = 180
2. x = 50 y= 130
Step-by-step explanation:
They're parallel.
We can label the unamed angle z.
So z = y
and 50 = x
There's 360 degrees in a circle, so x + y= 180 because it's half 360 and half a circle.
x=50
so 50 + 50 = 100.
360 - 100 = 260
so 260 ÷ 2 = 130
y = 130 because y and z are equal so they're the same number
