C Both (6,5) (3,-4)
D Neither

Answers

Answer 1

Step-by-step explanation:

3x-y=13

3x-y=13-13

3x-y=0

Answer 2
Your answer is (3, -4) .. to get that I plugged each set into the equation and solved to figure out which ordered pair makes this statement equivalent.. I got 13=13 after plugging in and solving so that makes it equivalent the other ordered pair makes an inequivalent outcome which was 9=13 ... I hope this helps

A basketball team needs to score more than 725 total points this season to set a new record. The team has already scored 165 points and it averages 70 points per game. How many more games does the team need to play if in order to set a new record? Assume the teams average number of points scored per game does not change.

Select the number line that includes the fewest number of games the team can play and still set the record.

Answers

Answer:

D.

Step-by-step explanation:

First, let's work out how many points they have to go. 725 - 165 = 560.

If they average 70 points per game, you'll need to divide 560 by 70.

560 / 70 = 8. Therefore, the team needs to play 8 or more games to get at least 725 points.

The answer
D because they need to play 8 games

Which would give you the greatest amount of pizza, three-12 inch round pizzas, two 18-inch round pizzas, or one 36-inch round pizza?

Answers

Answer:

All of them are equal in amount of pizza

Step-by-step explanation:

Some are bigger, but when you do the math,

3x12=36

2x18=36

and

36=36. So....they give all the same amount of pizza.

Well either three-12 inch round pizzas or one 36-inch round pizza... they both equal 36..

HELP PLESSE ITS MULTIPLE CHOICE

Answers

Answer:

Letter A

Step-by-step explanation:

First of all, we have to solve all the equations

First one is (4*1)-6

We have to use PEMDAS

which stands for

Parenthesis

Exponents

Multiplication

Divison

Addition

Subtraction

In (4*1)-6  

You have to do 4*1 first ~ which equals 4

the next step would be 4-6  ~  which equals -2

The next equation would be (1*4)-6

First do 1*4  ~ which is 4

Next 4-6  ~ which again equals -2

Next equation is (1*6)-(4-6)

Parenthesis first, 1*6=6

4-6=-2

6-(-2)

which equals 8

Our next equation is 6-(1*4)

1*4=4

6-4~ which equals 2

Our last equation is 4*(1-6)

Parenthesis comes first, so it would be 1-6 first

which equals -5

4*(-5) would be our final step  ~  which equals -20

All of our answers would be

-2 - from the top equation

-2 - from letter A

8 - from letter B

2 - from letter C

-20 - from letter D

which means Letter A is the answer.

Hope this is helpful.

How much simple interest would be earned on a certificate of deposit worth $2,000 over a period of 5years with an interest rate of 2%?

Answers

Answer:

$200 will be earned on a certificate of deposit worth $2000 over a period of 5 years with an interest rate of 2%

Step-by-step explanation:

Simple interest is applied on a amount as a whole. The interest is calculated for t time period where t is in years.

The simple interest is given by the formula:

[tex]I = Prt[/tex]

Here P is the principal amount, r is the annual rate and t is time in years

Given

P = $2000

t = 5 years

r = 2%

Putting the values in the formula

[tex]I = 2000 * 0.02 * 5 \\I = \$200[/tex]

Hence,

$200 will be earned on a certificate of deposit worth $2000 over a period of 5 years with an interest rate of 2%

Answer:$200

Step-by-step explanation:

Simple interest=(Principle×Rate×Time)/100

=(2000×2×5)/100

=$200

The answer is 1 11/15! Hope this helps!

1 1/15 is the anwser

first we put in improper fraction 3 2/5 its 17/5 for 1 2/3 is 5/3

first find the common denominator which is 15 so like this:

3 6 9 12 15

5 10 15

the common denominator is 15 now we have to multiply the numerator by how many time we did to the bottom so now are new number are

51/15 -20/15

=31 15

now make it to a proper fraction and 1 1/15 is the anwser

–2.5 + (–3.5) Which number line shows the sum? (and i know its not -6)

Answers

Answer:

6

Step-by-step explanation:

Answer:

-6

Step-by-step explanation:

1. Treat the problem like a subtraction problem because -2.5 + (-3.5) can be rewritten as -2.5-3.5

2. When adding or subtracting negative numbers, keep these rules in mind:

Same signs add and keep.

Different signs subtract.

Keep the sign of the higher number.

-2.5 -3.5 have the same sign, so add them up and keep the sign.

And you do get -6.
