Answer:

Step-by-step explanation:
So we have the inequality:

Definition of Absolute Value:

Note that the sign is flipped in the second case because we multiplied by a negative.
Add 5 to both sides to both equations:

Merge:

And we're done!
B) the side opposite angle B is the longest
So it wants you to write two equations, one for the number of fruit and another for the money spent. gather your important information first:
20 fruits for $11.50
apples cost $0.50
bananas cost $0.75
let's do the cost equation first. it's $0.50 per apple, so 0.50a, and $0.75 per banana, so 0.75b. the total cost is $11.50. put all of this information together:
0.50a + 0.75b = 11.50 ... so, the cost of apples bought plus the cost of bananas bought equals 11.50
note what your variables stand for. a represents the number of apples, b represents the number of bananas. to write an equation for how many fruits bought, you simply have to add these two and set them equal to 20 (the total number of fruits bought).
a + b = 20
and your other equation
0.50a + 0.75b = 11.50
these are your two equations. to solve the system of equations, you first want to get one variable alone; the first equation will be easier.
a + b = 20
a = 20 - b
now take this equation and plug it into the second equation.
0.50(20 - b) + 0.75b = 11.50 ... you'll notice that you only have one variable left: b. solve for it. the first step is to distribute 0.50 to the parentheses
10 - 0.50b + 0.75b = 11.50 ... combine like terms
10 + 0.25b = 11.50 ... subtract 10
0.25b = 1.5 ... divide by 0.25
b = 6
6 bananas were purchased. plug this back into an equation to find out how many apples were purchased.
a + 6 = 20 ... subtract 6
a = 14
14 apples and 6 bananas were bought.
Answer: A. The probability of drawing a red tile is 36% and the probability of NOT drawing a red tile is 64%
Step-by-step explanation:
Number of red tiles = 9
Number of blue files = 10
Number of green tiles = 6
Total number of tiles = 9 + 10 + 6 = 25
Probability of drawing red tile = 9/25 = 0.36 = 36%
Probability of drawing blue tile= 10/25 = 0.40 = 40%
Probability of drawing green tile = 6/25 = 0.24 = 24%
Based on the explanation above, the correct answe is option A "The probability of drawing a red tile is 36% and the probability of NOT drawing a red tile is 64%".
