Let
x------> the number of multiple choice question
y------> the number of free response question
we know that
-----> equation A
-----> equation B
Substitute equation B in equation A
Find the value of x
therefore
the answer is
the number of multiple choice question are
the number of free response question are
Y = mx + b
m = 1
b = 3
y = x+3
Hope it helps :)
Answer:
we need to know the variables
Step-by-step explanation:
Answer:
The value of r is 12.
Step-by-step explanation:
Since DM = 25, and DG + GM = DG, we can use this information to compose the equation:
r + 2 + 2r - 13 = 25
Combine like terms by adding r and 2r, and subtracting 2 and 13.
3r - 11 = 25
Add 11 to both sides.
3r = 36
Divide both sides by 3.
r = 12
3. a=0 b=0
4. a=5 b= 2
5. a=-5 b=2
