Answer:
x= 42
y= 23
Step-by-step explanation:
Set up a system of equations like this:
(4y-9)=(3x-43)
(2x+13)=(4y+5)
when two lines cross like this they form vertical angles, and vertical angles are always equal.
calculate the system of equations and you'll get x=42 and y=23
To find the measure of any of the angles just put x or y into the equation.
Answer:
Step-by-step explanation:
Part C- y=20x+600
Part D- To part D find the equations for all the cities.
Everett- y=15x+550
Chelsea- y=20x+600
Revere- y=50x+300
Since 2030 is 14 years away from 2016 x will equal 14.
Plug in 14 to each of the equations. Whichever has the highest result will be the answer.
Everett- y=15(14)+550 -----> y=760
Chelsea- y=20(14)+600 -----> y=880
Revere- y=50(14)+300 -----> y=1000
Revere will have the most chromebooks.

the answer is true
Step-by-step explanation:
Answer:
-20 + 30x
Step-by-step explanation:
-10(1) = -10
-10(-3x) = 30x
new equation
-10 + 30x -10
-10 + -10 = -20
-20 + 30x
