-3m + 9n -10
10m - 4n - 10
-4mn
9n - 3m + 10

Answers

Answer:

E

Step-by-step explanation:

The expression that is shown -3m + 9n -10 will be equivalent to the sum of the two original expressions written in standard form.

What are equivalent expressions?

Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.

We need to the expression into an equivalent form.

Therefore,  (3m + 2n - 6) + (-4 -6m + 7m)

= -3m + 9n -10

Hence, the sum of the expression is -3m + 9n -10

Now we put in n = -2 and m = 5 and evaluate the expression;

-3m + 9n -10

-3(5) + 9(-2) -10 = -43

Hence, the expression that is shown -3m + 9n -10 will be equivalent to the sum of the two original expressions written in standard form.

Answers

Answer:

14)$9,320.00. 15)Chen has 8 nickels, 2 dimes, and 6 quarters.     16)10%

Step-by-step explanation:

14)A = $9,320.00

I = A - P = $1,320.00

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 5.5%/100 = 0.055 per year.

Solving our equation:

A = 8000(1 + (0.055 × 3)) = 9320

A = $9,320.00

The total amount accrued, principal plus interest, from simple interest on a principal of $8,000.00 at a rate of 5.5% per year for 3 years is $9,320.00.

16)R = 1011.1111%/year

Equation:

r = (1/t)(A/P - 1)

Calculation:

Solving our equation:

r = (1/1)((1250/112.5) - 1) = 10.11111111

r = 10.11111111

Converting r decimal to R a percentage

R = 10.11111111 * 100 = 1011.1111%/year

The interest rate required to get a total amount, principal plus interest, of $1,250.00 from simple interest on a principal of $112.50 over 1 years is 1011.1111% per year.

Isaac and Juanita are collecting apple to make an apple pie. Isaac picks up 3 apples every minute and Juanita picks up 5 apples every two minutes. If they need 40 apples for a pie, about how long will it take both of them to collect enough apples?

Answers

Answer:

It will take them roughly 7.27 mintues

Step-by-step explanation:

To find this, model the amount of apples that can collect a minute using m as the minutes.

Isaac = 3m

Juanita = 5m/2

Now we can add them together and solve for when they will have 40 apples.

3m + 5m/2 = 40

5.5m = 40

m = 7.27

Answer:

about 7 minutes (7.27 minutes to be exact)

Step-by-step explanation:

Since they are working as a team, we can combine the two rates to see how many apples they collect together per minute. Isaac collects 3 p/min while Juanita collects 2.5 p/min equaling 5.5 apples p/min. 40 apples divided by 5.5 equals 7.27 minutes.

Step-by-step explanation:

I did it on I-ready

If Jerome wants to have read at least 85 pages by the end of the day on Friday, then the inequality that represents the situation will be 50 + 5p≥ 85

What is inequality?

An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.

here, we have,

Given that

the number of pages he read each day is "p", the number of pages he will read from Monday to Friday is 5p (Monday to Friday is 5 days)

If he has read  50 pages of a novel, the total number of books he has read will be 50 + 5p
