Let
x = points that a student needs to score on a test
p = points worth the exam.
to find how many points to student needs to score on a test to get a test score of 78%. it will be given by
x = 0.78 * p
Thus, in a 50-point test, the number of points the student needs to get to get a test score of 78% will be
x = 0.78 * 50 = 39 points.
Answer:4 × 109
+ 3 × 108
+ 6 × 107
+ 5 × 106
+ 4 × 105
+ 2 × 104
+ 1 × 103
+ 0 × 102
+ 0 × 101
+ 6 × 100
Step-by-step explanation:
I think the answer would be -$22.27 because 89.08 divided by for is 22.27
So to start you should get x and y on the same side and get the numbers on one side. Then you should cancel out a variable. Because both y’s are 1 and they are opposite charges they will both cancel out to 0. Then add what is remaining which is the 2x and the 3x and equal that to +9-4 which equals 5. You want x to be all by itself so you would divide both sides by 5 and get that x=1. Then you would just substitue and solve for y. Hope this helped!
