Let the score on her seventh test be "x".
SO,

∴ He must get 104% on his seventh test to get an average score of 90%
Answer:
y − 3 = 2(x − 1)
Step-by-step explanation:
The point-slope form of the equation of a line with slope m through point (h, k) is ...
y -k = m(x -h)
You have m=2, h=1, k=3, so the equation is ...
y -3 = 2(x -1)
we know that the shaded side is 90 degrees and we are given 28 degrees
So we add 90+28 and we get 118
Since a triangle has 180 degrees, we subtract 180-118 to fins the missing angle measure
180-118=62
x=62
Your equation is 180=90+28+x
Square root is this 4 and -4 are square roots to 16 because 4^2= 16
The way to find the difference between 5y - 3 you have to first do the inverse operation of multiplication which is division.
