Step-by-step explanation:
Answer:
Yes
Step-by-step explanation: Its .5 higher
Answer:
There are 14 4-point questions and 26 2-point questions.
Step-by-step explanation:
m = number of 4-point questions
n = number of 2-point questions
m+n =40
4m + 2n =108
You can solve system by elimination:
Multiply the 1st equation by -4 and keep the 2nd equation the same.
−4(m+n=40) → -4m -4n= -160
4m+2n=108 add them up
-2n = -52 divide both sides by -2
n = 26
plug it back in to solve for m
m + n = 40 →m + 26 =40 subtract 26 to both sides
m = 14
<span>x + 3y = 18
x + 2y = 14
------------------subtract
y = 4
</span>x + 3y = 18
x + 3(4) = 18
x + 12 = 18
x = 6
answer: solution (6,4)
That's the answer to these questions.
