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

Answer:

d.revenies increased by 500

Answer: 60%

Step-by-step explanation:

Our answer is 60 because:

57 ÷ 95 = 0.6

We take the 0.6 and multiply.

We get 60% as an answer.

Answer:

60%

Step-by-step explanation:

To find the answer to this equation, you need to use the percent composition formula. It is as follows:

[tex]\frac{part}{whole} * 100 = percent[/tex]

Let's plug in what the question gives us into the equation:

[tex]\frac{57}{90} *100 = 60[/tex]

Therefore, the answer to your question is 60%!

Answer:

  (x, y) = (-6, -7)

Step-by-step explanation:

Multiply the first equation by 7 and add that to the second.

  7(x +y) +(5x -7y) = 7(-1) +(79)

  12x = 72

  x = 6

  y = -1 -x = -1 -6 = -7

The solution is (x, y) = (6, -7).

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|."

Answer:

60 sweatshirt Or 45 jackets

Step-by-step explanation:

Total amount = $1,440

Sweatshirts = $24

Jackets = $32

What is the greatest number of sweatshirts or jackets the team can purchase?

The greatest number of sweat- shirts the team can purchase = Total amount / cost of sweatshirt

= $1,440 / $24

= 60

The greatest number of jackets the team can purchase =Total amount /cost of jackets

= $1,440 / $32

= 45

Therefore, the greatest number of sweatshirts or jackets the team can purchase is

60 sweatshirt

Or

45 jackets

Answer:

60 Sweatshirts

45 jackets

Step-by-step explanation:

take the amount of money divide by the cost of the jacket or sweatshirt.

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.

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.

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  

A function maps one input to one output, where x is the input and y is the output.

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

Answer:A. 5m + 40

see in the picture, u can see that the line passes through (0;40) and (10;90)

suppose: the equation of the line is y = am + b (a ≠ 0)

because the line passes through (0;40) => 40 = b

the line passes through (10;90)              => 90 = 10a + b

=> b = 40

    a = 5

=> y = 5m + 40
