What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

The weekly per hour of Tasha last week = $ 422.75

The extra overtime pay of Tasha for 3 hours = $ 42.75

The total number of hours working = 40 hours

So , the equation will be

The weekly per hour of Tasha without overtime = weekly per hour of Tasha last week - overtime pay of Tasha for 3 hours

Substituting the values in the equation , we get

The weekly per hour rate of Tasha without overtime = 422.75 - 42.75

The weekly per hour of Tasha without overtime = $ 380

So , The weekly per hour rate of Tasha A = The weekly per hour rate of Tasha without overtime / total number of hours working

Substituting the values in the equation , we get

The weekly per hour rate of Tasha A = 380 / 40

The weekly per hour rate of Tasha A = $ 9.50

Therefore , the value of A is $ 9.50

Hence , The weekly per hour rate of Tasha is $ 9.50

Answer:

144°

Step-by-step explanation:

let the smaller angle be x then the larger angle is 4x

The sum of a linear pair of angles = 180°, thus

x + 4x = 180 , that is

5x = 180 ( divide both sides by 5 )

x = 36

Thus the larger angle = 4x = 4 × 36 = 144°

Answer:

let the smaller angle be x.Then the bigger angle will be 4x.

x+4x= 180

or, 5x=180

or, x=180/5

there fore, x=36

Again,

4x=4×36

=144

The larger angle is 144.

Answer:

90 hour

Step-by-step explanation:

300 minutes is for 1 school week

so if you multiply 300 minutes for 18 weeks it results as 5400 minutes.

300 × 18 = 5400 minutes

To get the number of hours you should divide 5400 minute by 60 minutes      ( which is one hour )

5400 ÷ 60 =. 90 hours

You spent a total of 90 hours studying math in 18 weeks.

Step-by-step explanation:

If L lies on the line segment KM. It means that:

K_____?__________L___2__M

|<--------------------19------------------->|

Given that:

LM = 2

KM = 19

So,

KM = KL + LM

19 = KL + 2

Subtracting 2 to both sides

KL = 19-2

KL = 17

Answer:

She has 7 nickels, 11 dimes and 10 quarters

Step-by-step explanation:

Total value =$3.95

Let

Nickel = x

Dimes = x + 4

Quarters = x + 3

Every

Nickel = 5 cents

Dimes = 10 cents

Quarters = 25 cents

Total cents = $3.95 × 100

= $395

5n + 10d + 25q = 395

5(x) + 10(x+4) + 25(x+3) = 395

5x + 10x + 40 + 25x + 75 = 395

40x + 115 = 395

40x = 395 - 115

40x = 280

Divide both sides by 40

x= 280/40

= 7

x= 7

Nickel = x = 7

Dimes = x + 4

=7+4

=11

Quarters = x + 3

=7+3

Answer:

-22 is the value of K.

Step-by-step explanation:

A simple way to see how far a mid-point or end-point is from another is by adding or subtracting. For this figure I added to see how many numbers would add twice to get from -15 to -29. -14 is the exact number from -15 to -29; divide that by 2 to get half of -14 which is -7. -7 + (-15) gives you -22.

The location of K so that JK is 1/7 of JL is -22.

Given that, K lies between J and L.

We need to find the location of K so that JK is 1/7 of JL.​

In geometry, a line segment is a part of a line that is bounded by two distinct end points and contains every point on the line that is between its endpoints.

Now, the distance between the points J and L on the number line is 14.

So, 1/7(14)=2

Part A

Answers:

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

Explanation:

The variables are simply letters. They are placeholders for numbers to be plugged in later. Think of them like empty boxes where numbers will go. In this case, the variable h represents the number of hours Tyler works, and c is the number of new accounts she opens.

The coefficients are the numbers multiplied with the variables. They are to the left of the variable.

The constant 50 is not attached to any variable.

===================================

Part B

Answer: She earns $618.5

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

Explanation:

We're told she worked 37 hours. So we'll replace h with 37.

Also, she opened 12 new accounts. So c = 12

This means...

10.50*h + 15*c + 50

10.50*37 + 15*12 + 50

388.5 + 180 + 50

618.5

is the amount she earns

===================================

Part C

Answer: The coefficient changes. Specifically, the coefficient 10.50 changes to 11.25

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

Explanation:

The constant never changes (hence the name) no matter how much of a raise Tyler gets. The other coefficient doesn't change either because she would still get $15 per new account. All that's changed is the hourly wage.

If we're told that Tyler got a raise to $11.25 per hour and she now earned $20 per new account, then both coefficients would change and the new equation would be 11.25h+20c+50

Answer:

17.3 in

Step-by-step explanation:

Given the following :

Length of tank = 20 inches

Width of tank = 10 inches

Amount of water poured into tank = 15 gallons

Volume(V) of tank (rectangular prism)

V = Length × width × height

Height = h

1 gallon = 231 inch³

15 gallons = (231 × 15) = 3465 in³

Hence V = 3465 in³

3465in³ = 20 in × 10 in × h

3465 in³ = 200h

h = 3465 / 200

h = 17.325 in

Height = 17.3 in ( nearest tenth)

this is because

C = 2pi*r

Answer:

Option C is the correct answer.

C.  5•(-20)

Step-by-step explanation:

We are told that the insurance payment for the car follows a certain pattern that can be represented through an expression. The payment is decreasing by $20 every year. As we don't know the total payment amount per period, so we cannot calculate how much is paid per period/year for insurance but we can calculate the rate at which this payment is decreasing.

Change in payment = t * (-20)

The above expressions can be used to calculate the amount of change in payment i payment is decreasing by a constant $20 every year, after t years.

So, if we want to calculate the change in payment after say 5 years, we can replace t with 5 in the equation and calculate the change,

Change in payment = 5 * (-20)

Change in payment = - $100
