I will solve your system by substitution.
(You can also solve this system by elimination.)
2x+y=−2;−3x+2y=3
Step: Solve2x+y=−2for y:
2x+y+−2x=−2+−2x(Add -2x to both sides)
y=−2x−2
Step: Substitute−2x−2foryin−3x+2y=3:
−3x+2y=3
−3x+2(−2x−2)=3
−7x−4=3(Simplify both sides of the equation)
−7x−4+4=3+4(Add 4 to both sides)
−7x=7
−7x
−7
=
7
−7
(Divide both sides by -7)
x=−1
Step: Substitute−1forxiny=−2x−2:
y=−2x−2
y=(−2)(−1)−2
y=0(Simplify both sides of the equation)
Paula ran 3 1/4 kilometers. Omar ran 4,200 meters. Who ran farther and by how much?
Answer:
Omar ran farther
Step-by-step explanation:
Paula ran 3250 meters and Omar ran 4200 meters. Omar ran 950 more meters than Paula
omar because 3 1/4 meters is the same as 3250 meters so then
4200>3250 so omar did more

A local restaurant only sells burgers and cokes. 3 burgers and 5 comes cost $17, while 6 burgers and 9 cokes cost $33. What’s the price of a burger?
Answer:
The price of a burger is $4 and that of cone is $1.
Step-by-step explanation:
Let the cost of burger is x and that of cone is y.
ATQ,
3x+5y = 17 ....(1)
And
6x + 9y = 33 ...(2)
Multiply equation (1) by 2.
6x + 10 y = 34 ...(3)
Subtract equation (2) from (3)
6x + 10 y-(6x + 9y) = 34 - 33
6x + 10 y-6x- 9y = 1
y = 1
Put the value of y in equation (1)
3x+5 = 17
3x = 12
x = 4
So, the price of a burger is $4 and that of the cone is $1.
A survey of 800 students yielded the following information: 519 were seniors, 430 were commuters, and 300 of the seniors were commuters. How many of the 800 surveyed students were seniors or were commuters?
Answer:
The number is [tex](S \ u \ C ) = 649[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 800
The number of seniors is S = 519
The number of commuters is C = 430
The number of of seniors that are commuters is [tex](S\ n \ C )= 300[/tex]
Generally the number of 800 surveyed students who were seniors or were commuters is mathematically evaluated as
[tex](S \ u \ C ) = S + C - ( S \ n \ C )[/tex]
=> [tex](S \ u \ C ) = 519 + 430 - 300[/tex]
=> [tex](S \ u \ C ) = 649[/tex]
james bought a pound of chicken for 2.99 a pound of cheese for 5.99 and a bag of potatos for 3.99 find his total at checkout if the sales tax is 7%
Answer:
13.88 (if you round up)
Step-by-step explanation:

12.97 * 7% = .9079
12.97 + .9079 = 13.8779
The graph of a system of equations will intersect at exactly 1 point?
Answer:
A system of equations can intersect at no points; this is when the lines are parallel, which means they have the same slope and different y-intercept. A system of equations can intersect at one point; this is when the lines have different slopes.

Find the measures of the exterior angles.
Answer:
The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles. (Non-adjacent interior angles may also be referred to as remote interior angles.) FACTS: An exterior ∠ is equal to the addition of the two Δ angles not right next to it.
