Consider the expression –3(y – 5)2 – 9 + 7y.Which statements are true about the process and simplified product? Check all that apply.

A=The first step in simplifying is to distribute the –3 throughout the parentheses.
B=There are 3 terms in the simplified product.
C=The simplified product is a degree 3 polynomial.
D=The final simplified product is –3y2 + 7y – 9.
E=The final simplified product is –3y2 + 37y – 84.

Answers

Answer 1

Answer:

Answer: Option 'B' and 'E' are correct.

Step-by-step explanation:

Since we have given that

$-3(y-y)^2-9+7y$

Simplification needs a few steps:

$-3(y-5)^2-9+7y\n=-3(y^2+25-10y)-9+7y\n=-3y^2-75+30y-9+7y\n=-3y^2+37y-84$

So, Option 'B' and 'E' are correct.

As Option 'B' says there are 3 terms in the simplified product, which is true.

Sharon’s turtle escaped from her backyard sometime in the last few hours. According to her calculations, the farthest the turtle could have gone is 4 blocks down the road in either direction. If Sharon lives on the 112th block of town, which equation can be used to find the block numbers that represent the farthest distance that the turtle may be?

Answers

The farthest distance of the turtle can be solved with the following equations:

x = 112 + 4
x = 112 - 4

By solving the equations, we conclude that the turtle can be found either in the 116th block or the 108th block.

On a trip, the fare was 50¢ for each adult and 25¢ for each child. If 30 passengers paid $12.25, how many adults and children went?Is this the right way to set up the equation?
50x + 25(30 - x) = 1225

Answers

Fare for each adult = 0.50 dollars
Fare for each child = 0.25 dollars
Total number of passengers = 30
Total amount paid for the trip = 30 dollars
Lat us assume the number of adults = x
Then
The number of children = 30 - x
So
0.50x + 0.25(30 - x) = 12.25
50x + 25(30 - x) = 1225
This is the right way of setting up the equation and you have done it correctly.

25x + 50x = 30(1225) is the equation that wouldn't work

Step-by-step explanation:

Given,

Total passenger = 30

There can be only two cases,

Case 1 : Let x be the number of adults,

So, the number of children = 30 - x,

Since, the total fare is $12.25 or 1225¢ ( 1 dollar = 100 cents ) in which 50¢ is for each adult and 25¢ is for each child,

⇒ 50x + 25(30 - x) = 1225,

Case 2 : let x be the number of children,

So, the number of adult = 30 - x,

The equation would be,

⇒ 50(30 - x) + 25x = 1225

Hence, the equations that could not be used to solve the given problem is,

25x + 50x = 30(1225)

Find 12 1/2% of 96 men

Answers

$12(1)/(2)$ percent of 96 men is 12 men.

What is percentage?

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, $12(1)/(2)$ % of 96 men.

Here, $12(1)/(2)$ % =12.5%

Now, 12.5% of 96

12.5/100 ×96

= 0.125×96

= 12 men

Therefore, $12(1)/(2)$ percent of 96 men is 12 men.
