Answer:
Step-by-step explanation:
So since each question is 5% (100/20=5)
we can do ((13*5)/2) because of half credit we divide by two
now we get 32.5% back
32.5%+35%=67.5%
unless of course of extra points on other assignments, the highest grade you can get in that class (if every other thing is a 100%) is an 87 if im not mistaken.
To solve a square root, get the ^2 on one side and the 81 on the other side.
add 81 to both sides.
c^2 = 81
to clear the power of 2, take the square root of both sides.
c = + - sqrt81
c = + - 9
c = 9 and c = -9
Answer:
n = 0
Step-by-step explanation:
Multiply parenthesis by 3 and get:
1.) 18 + 9n = 5n + 18 + 3n
Then cancel the equal terms:
9n = 5n + 3n
Collect like terms:
9n = 8n
Move variable to the left:
9n - 8n = 0
n + 0
Plugin the value of 0 into x:
3 (6 + 3 x 0) = 18
5 x 0 + 3 x 0 + 18 = 18
*If the plugged in value have the same result than the answer is correct because 18 + 18.
Answer: 76 degrees
Step-by-step explanation:
m<abc = m<1 + m<2
4x+12=(2x-7)+(3x-4)
x=23
180=4x+12+m<3
m<3=76
