Answer:
2x-15
Step-by-step explanation:
x+2x-15=90
3x-15=90
3x=90+15
x=105/3
the other angle is 55
This is experimental probability, since it is based on the outcome of an experiment.
Area = 11 * 1 + 7 * 7 + 1/2 * 9 * 9 = 11 + 49 + 40.5 = 100.5
Answer is C
Answer:
Since ZE and ZF are vertical angles, they are congruent.
8x+8 = 2x+38
8 = 2x-8x+38
8 = -6x+38
8-38 = -6x
-30 = -6x
x = -30/-6
x = 5
Let x = the amount of grapes that can be bought for 0.40.
Note: By 90 I assume you mean 90 cents. The same for 40.
12/x = 0.90/0.40
0.90x = 12(0.40)
0.90x = 4.80
x = 4.80 ÷ 0.90
x = 5.33333
We can round the decimal to the ones place to get 5 grapes.
