Step-by-step explanation:

Answer 2

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

With the regrouping strategy, we get,

50 x 10; 7 x 10; 50 x 8; 7 x 8

Option B is the correct answer.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

57 x 18

This can be written as,

(50 + 7) x (10 + 8)

Simplifying we get,

(50 x 10) + (50 x 8) + (7 x 10) + (7 x 8)

Now,

With the regrouping strategy, we get,

(50 x 10)

(50 x 8)

(7 x 10)

(7 x 8)

Thus,

With the regrouping strategy, we get,

50 x 10; 7 x 10; 50 x 8; 7 x 8

Option B is the correct answer.

find the mean for the scores : 3810;5300;8540;4300,5340

Answers

Answer: 5458

Step-by-step explanation: So the mean is the same thing as the average. To find the mean you add up all of the numbers, and then divide by 5 because there are five numbers. So the sum would be 27,290. Then that divided by 5 would be 5458.

The mean of the scores 3810, 5300, 8540, 4300 and 5340 is, 5466.

What is mean?

Mean is an average of values of a set. Arithmetic mean, geometric mean and harmonic mean are the type of mean.

The given scores are

3810, 5300, 8540, 4300, 5340

Total number of terms is 5.

To find the mean, use formula,  

Mean = sum of terms/number of terms.

Mean = (3810+5300+8540+4300+5340)/5

          = 27330/5

          = 5466

Mean of the given score is, 5466.

a bank teller. helps two customers omar makes a $15 withdrawal so he balance changes by -$15. jakes makes a $10 deposit so his balance changesby $10

Answers

Answer:

D. Omar's transaction involves more money, because |-15| is greater than |10|.

Step-by-step explanation:

The absolute value of a number is simply the magnitude or numerical value of a number while ignoring any sign attached to it. For example, given that x is a real number, absolute value of x, |x| = x. The absolute value of x does not take account of any sign attached to it.

Thus:

The absolute value of Omar's transaction is given as |-15| = 15.

While that of Jake is |10| = 10.

15 is greater than 10.

Therefore, we can conclude that:

"Omar's transaction involves more money, because |-15| is greater than |10|."

if she has 2 necklaces already, she needs 16 more because 18-2=16.

$16 because if you subtract 2 from 18, it’s 16.

Iḿ sorry this is prob. so easy I just bad at math. :(

Answers

Answer:

Hmm, I think the answer is 57.5.

Step-by-step explanation:

Since 46 = 3/4, we divide 46 by 4 to get one fourth. That is 11.5 . Then, multiply it by 4 to get by one minute. 11.5 x 4 = 57.5  

The answer is 48/1. You have to change 48 into 48/1. Then just rewrite the equation. You then would want to multiply those and what you would get would be 144/3. To simplify you would have to divide 144 by 3 and what you would get would be 48/1 or just 48. Hope this helps! Please mark this!

You have to solve for x and y!

Answer:

x=−175 and y=−1220

Step-by-step explanation:

Based on the Vertical Angles Theorem, -7x+5=y

Since we know that 2 angles that form a line when combined equal 180 degrees, we know that (4-12x)+y=180

-7x+5=y

(4-12x)+y=180

Now we solve the system:

7x+5=y;−8x+y=180

First, we solve 7x+5=y for y:

7x+5+(−y)=y+(−y)

7x−y+5=0

7x−y+5+ (−5)=0+ (−5)

7x−y=−5

7x−y+(−7x)=−5+(−7x)

−y=−7x−5

-y/-1=(-7x-5)/-1

y=7x+5

Now we will substitute 7x+5 for y in the other equation:

−8x+y=180

−8x+7x+5=180

−x+5=180

−x+5+(−5)=180+(−5)

−x=175

-x/-1 = 175/-1

x=−175

Finally, we'll substitute -175 for x in y=7x+5:

y=7x+5

y=(7)(−175)+5

y=−1220

Over three days I earn 2568. On the first day I made twice as much as the second day. On the third day I made three times as much as the second day. How much did I earn on the first day.

Answers

Answer:

I earned $856 on the first day

Step-by-step explanation:

Let's call

x = earning on the second day

2x = earnings on the first day

3x = earnings on the third day

The total earnings are $2568, thus

x + 2x + 3x = 2568

Simplifying:

6x = 2568

Dividing by 6:

x = 2568/6

x = 428

I earned $428 on the second day.

2x = 2*$428 = $856

I earned $856 on the first day
