Answer:

Four siblings have a dog walking business. The table shows the hours worked by each sibling. Each sibling earns $25.50 per hour and the total number of hours worked is represented by 10h+15 , where h represents the number of hours Michael worked.

Martin 2.5h+3

Emilio 4(h−2)

Michael h

Mario 31

The algebraic expression is the combination of variable and constants with some mathematical operation between them. The Earning of the four siblings are $357, $244.8, $112.2 and  $790.5 respectively.

An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.

The variable part of an algebraic expression can never be added or subtracted from the constant part.

Given that,

The earning of the siblings per hour is $25.50.

Total number of hours worked is 10h + 15.

As per the problem the value of h can be found by equating the total number of hours to the sum of hours worked by each sibling as given in the table as follows,

2.5h + 3 + 4(h - 2) + h + 31 = 10h + 15

⇒  2.5h + 3 + 4h - 8 + h + 31 = 10h + 15

⇒  7.5h + 26 = 10h + 15

⇒  2.5h = 11

⇒  h = 11 / 2.5

⇒  h = 4.4

Thus, the earning of each sibling can be calculated by substituting h = 4.4 in their working hour and multiplying it by $25.50 as follows,

Earning of Martin is given as,

(2.5 × 4.4 + 3) × $25.50 = $357

Earning of Emilio is given as,

4(4.4 − 2) × $25.50 = $244.8

Earning of Michael is given as,

4.4 × $25.5 = $112.2

Earning of Mario is given as,

31 × $25.50 = $790.5

Hence, the earnings of the four siblings are as Martin :  $357, Emilio : $244.8, Michael : $112.2 and Mario : $790.5.

Correct answer:

C) 3x and 8x

Step-by-step explanation:

At first I thought the correct answer was D.

You may Have thought that too but that is not the correct answer.

You see 3x and 8x are both like terms because they both have x

but..

The other 3 does not have a x it has a y

Answer:

Step-by-step explanation:

1) 1 +4=5      

      5+(4+1) = 10

     10 +(4+2)=  16......

2)       0+1 = 1

            1+2 = 3

            3+4 = 7

             7+8= 15          

 ADD THE NEXT NUMBER   15+16 = 31

3)           0+1 = 1

                1+1=2

               2+1= 3

               3+2 = 5

               5+3= 8                               8+5=13.........

Answer:

(4,-1)

Step-by-step explanation:

x-4y=8

-4y=-x+8

y=1/4x-2

The solution to the equation x - 4y = 8 is an ordered pair (4,-1).

A solution to an equation is a number that can be substituted for the variable to provide a true number statement.

The equation is given in the question, as follows:

x - 4y = 8

To determine the ordered pair (x,y) of the solution, substitute the value of x = 4 in the equation, and solve for y:

4 - 4y = 8

- 4y = 8 - 4

- 4y = 4

y = - 4/4

Divided by -4 into both sides of the equation, we get

y = - 1

Thus, the solution to the equation is an ordered pair (4,-1).

In order to find the solution, You would first line line the equation up. then, you would subtract -200 by 15. The answer would be -185. I know the answer will be negative because -200 is too big for 15 to make the solution positive. If you had a positive 201 plus -200 the answer would be equivalent to a positive one because the positive would cancel out the negative.

Included: Negative, positive, equivalent.

explanation/ statement:

"I think I should subtract -200 by 15. which one equal -185. I know the answer will be negative because -200 is too big for 15 to make the solution positive.

In fact, If you had a positive 201 plus -200 the answer would be equivalent to a positive one because the positive would cancel out the negative one.

Answer: x= 1/3t

Step-by-step explanation: I think

Answer:

Step-by-step explanation:

Answer:

The output would depend on the input so relating this to the question, the input is the time (in minute) and the output is the amount of water left in the tank

We can give a letter 't' for the time, the input, and f(t) for the output

----------------------------------------------------------------------------------------------------------------

The original amount of water in the tank is 10450, so this will be the fixed constant.

The amount of water lost per minute is 270 so this will be the term that varies depends on the variable of time, we write this as 270t

The function is given f(t) = 10450 - 270t

--------------------------------------------------------------------------------------------------------------

Given, t = 10

f(10) = 10450 - 270(10)

f(10) = 7750 ml

Step-by-step explanation:

Answer:

 Part A:

Since the rate of 270 ml per minute has units of ml per minute, then yy must have units of ml and x must have units of minutes. The input must then be the number of minutes the tank is leaking for and the output is the number of ml of water remaining in the tank.

Part B:

Since the tank is leaking 270 ml per minute, then after x minutes, 270x ml of water has leaked out of the tank. The tank initially has 10,450 ml of water so after x minutes, there is y=10,450−270x ml remaining in the tank.

Part C:

After x=10 minutes, the amount of water remaining in the tank is y=10,450−270(10)=10,450−2,700=7,750 ml. There are 1,000 ml in 1 liter so 7,750 ml = 7.75 liters. There are then 7.75 liters of water left in the tank after 10 minutes.

Answer:

Part A: She borrowed: 3700

Part B: She would pay 555 in interest.

Step-by-step explanation:

Since, simple interest is,

Where, P is the principal amount,

r is the annual rate of interest,

t is time ( in years ),

Part A :  Here, S.I. = $ 444,

t = 3 years,

r = 4 %,

Thus,

Hence, She borrowed $ 3700.

Part B :

Here, r = 5 %, t = 3 years, P = $ 3,700,

Hence, She would pay $ 555 interest.
