To the find average of the test scores, we need to find the mean.
To find the mean, all we need to do is add up all the numbers and then divide the answer by how many numbers there are
81 + 83 + 85 = 249
249 ÷ 3 = 83
Therefore, the new average is 83
Hope this helps
Answer:
x=4
Step-by-step explanation:
-5(4-x)=-5x+20
We simplify the equation to the form, which is simple to understand
-5(4-x)=-5x+20
Reorder the terms in parentheses
+(-20+5x)=-5x+20
Remove unnecessary parentheses
-20+5x=-5x+20
We move all terms containing x to the left and all other terms to the right.
+5x+5x=+20+20
We simplify left and right side of the equation.
+10x=+40
We divide both sides of the equation by 10 to get x.
x=4
To find the x-intercept, make y equal to 0. Then you get (7/2,0)
To find the y-intercept, make x equal to 0. Then you get (0,7)
