To answer this, set up a system of equations. What we know is that
5x + 2y = 100
And...
x+y=38
x represents the unknown number of 5 points questions
y represents the unknown number of 2 point questions
In my opinion the easiest way to solve this is to use substitution (that is when you find out the value of one variable, either x or y, and substitute that value as the variable).
So,
x+y=38
Subtract x from both sides
y=38-x
Now, plug (38-x) in as y in the other equation.
5x + 2(38-x) = 100
5x + 76-2x= 100
3x+76=100
3x=24
x=8
Now that you know that x=8, you can solve for y.
5x+2y=100
5(8)+2y=100
40+2y=100
2y=60

y=30
X=8
Y=30
There are 8 five point questions on the test and 30 two point questions on the test
Answer:
90 divided by 2
Step-by-step explanation:
you're going to do 90 divided by 2 and then you get 45
Answer:
y=2x-5
Step-by-step explanation:
first because if a linear equation is graphed to be perpendicular has to have the same slop y=2x which is equivalent to going up two over one on agrao from the +1 point to pass through (3,1) start at the point (3,1) go down two over until you find the y intercept which in this is -5 five so y=2x-5 is the answer.
