It should be 91 because 8 + 1 = 9, and if you go any further, it would turn into the hundreds place
Answer
Step by Step Explanation
1) Due to the Centroids Theorem we can say that:
AP=2/3AE
AP=2/3*21
∴AP=14
2) Finally, AE =AP+AE
21=14+7 ⇒21=21 True
AP =2PE verifies the Theorem too.
So, the size is 14 .

STEP 1:
identify variables and equations
x= larger number
y= smaller number
FIRST EQUATION
x + y= 42
SECOND EQUATION
y= 2x - 63
STEP 2:
substitute the y value in second equation in for y in first equation
x + y= 42
substitute y value from 2nd equation
x + (2x - 63)= 42
combine like terms
3x - 63= 42
add 63 to both sides
3x= 105
divide both sides by 3
x= 35 larger number
STEP 3:
find y value; substitute step 2 x value into either original equation
x + y= 42
35 + y= 42
subtract 35 from both sides
y= 7 smaller number
ANSWER: larger number is x= 35; smaller number is y= 7.
Hope this helps! :)
Answer:

Step-by-step explanation:
If she makes a minimum profit, we need to use the symbol
, which indicates minimum quality.
Let's call
profit, so the inequality which represent this problem would be

The price of the car is multiplied by 1.15, because she must add her profit comission which is 0.15 or 15%.
Therefore, the right answer is the last choice.
