Add 72, 75, and 83, which equal 230. Then, since there are three values, you divide the total (230) by 3, which would equal 76.6 (cont), therefore meaning they can only raise their average (using the three tests, from a base grade of 0) to a 76.6 percent (or 77 if teacher rounds grade)
Answer:
x=72
Step-by-step explanation:
x=3/4x+18
4(x=3/4+18)
4x=3x+72
x=72
Answer:
NO, YES, YES, NO
Step-by-step explanation:
Subsitute the number they give you and then solve. Finally, see if the equation is true.
13 - 7 = 20 This is equation is not true. (NO)
15 · 8 = 120 This equation is true. (YES)
24/12 = 2 This equation is true. (YES)
5 = 10 + 5 This equation is not true. (NO)

Sum of interior angles = (n-2) × 180<span> = (5-2) x 180 = 3 x 180 = 540
so
x + 90 + 107 + 144 + 138 = 540
x + 479 = 540
x = 540 - 479
x = 61</span>
