Answer:
he makes 14 field goals and 7 extra point kicks
Step-by-step explanation:
- f=#of field goals
- e=extra kick points
- f+e=21
- 3f+1e=49
- subtract top from bottom
- 2f=28
- f=14
27) if a = 1/a
multiply both sides by a
a * a = 1/a * a
a^ 2 = 1
Answer is D) 1
28)
6 x 75 = 450
7 x 80 = 560
8 x 85 = 680
9 x 90 = 810
Total all students in class = 6 + 7 + 8 + 9 = 30 students
Total score of whole class:
450 + 560 + 680 + 810 = 2500
Average = 2500 /30 = 83.3 = 83 1/3
Answer is C) 83 1/3
I'm going to make some assumptions here:
That your sqrt8x= sqrt4+2x means √(8x) = √(4+2x). (There are other interpretations.)
Squaring both sides, 8x = 4 + 2x, or 6x = 4, or x = 4/6, or x = 2/3.
Answer:
Formula for percent change is C = {x_2 - x_1}/{x_1}
C = relative change
x_1 = initial value
x_2 = final value
