Answer:

d. w=13.34

Step-by-step explanation:

The value of w is 13.34 for the given equation. The correct answer is option D.

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 as follows:

3(−5.8 + w) = 22.62

First, we distribute the 3 on the left side of the equation:

-17.4 + 3w = 22.62

Next, we isolate the variable by adding 17.4 to both sides of the equation:

-17.4 + 3w + 17.4 = 22.62 + 17.4

3w = 40.02

Finally, we solve for w by dividing both sides of the equation by 3:

w = 13.34

Therefore, the value of w is 13.34, so the answer is option D.

According to the arrangement, he must pay a late fee of $25 each month.

The inverse of multiplication is division. If three groups of four add up to twelve, twelve divided into three equal groups adds up to four in each group. The basic purpose of splitting is to determine how many equal groups have been formed or how many people are in each group when equitably sharing.

To divide two numbers, use the formula Dividend Divisor = Quotient + Remainder. The dividend seems to be the number being divided in this case. The number that divides the number (dividend) into equally equal parts is known as the divisor.:

The expression that shows how many total basket the Cavaliers made during the season is 1978+f

The total number of free throws = 1484

The number of two point field goals = f

The number of 3 point field goals = 494

Total number of basket Cavaliers made during the season = Number of free throws + Number of two point goals + Number of three point field goals

Substitute the values in the equation

Total number of basket Cavaliers made during the season= 1484 + f +494

Add them together

1484+ f +494= 1978+f

Hence, the expression that shows how many total basket the Cavaliers made during the season is 1978+f

Answer:

Step-by-step explanation:

algebraic equation solving x, we concluded that In the year 1980 the approximate number of oil barrels imported from Country B per day will be 1.89 million.

An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation. The variables in the previous sentence, y and x, are referred to as a "linear equation with two variables" at times.

y=0.051x+1.38

Let us put y = 1.89

1.89 = 0.051x + 1.38

⇒ x = 0.51/0.051

⇒ x = 10

After ten years, 1.89 million oil barrels per day will be roughly imported from Country B.

Around 1.89 million oil barrels per day would be imported from Country B in the year 1980.

Step-by-step explanation:

The measures of the angles are x = 40, x = 110 and y = 70

Angles are formed when two or more lines intersect

The figure represents the given parameters

On the figure, we have the following highlights

Angle 3 and angle y are corresponding angles.

Corresponding angles are congruent

So, we have

y = Angle 3

From the figure

Angle 3 = 70

So, we have

y = 70

The angle on a straight line is 180 degrees

So, we have

x + y = 180

This gives

x + 70 = 180

Evaluate the like terms

x = 110

The triangle is an isosceles triangle.

So, we have

y = Angle 2

This means that

Angle 2 = 70

The sum of angles in a triangle is 180

So, we have

z + y + Angle 2 = 180

This gives

z + 70 + 70 = 180

Evaluate

z = 40

Hence, the measures of the angles are x = 40, x = 110 and y = 70

Answer:

28 nickels and 17 dimes

Step-by-step explanation:

A nickel is worth 5 cents and a dime is worth 10 cents

If there are X nickels and Y dimes

Total value = 5X + 10Y cents

$3.10 == 3.10 x 100 = 310 cents

So 5X + 10 Y = 310

Divide both sides by 5 to get

5X/5 + 10Y/5 = 310/5

X + 2Y = 62  (1)

The total number of coins is X + Y and is given to be 45

X + Y = 45    (2)

Subtract Eq(2) from Eq(1) to get

X + 2Y - (X + Y) = 62-45 = 17

X + 2Y - X - Y = 17

Collecting like terms

(X - X) + (2Y - Y) = 17

Y = 17

So number of dimes = 17

To find X, the number of nickels use equation (2)

X + 17 = 45

Subtract 17 from both sides

X + 17 - 17 = 45 - 17

X = 28

So number of nickels = 28

144 child tickets was sold out.

Answer:

Adult tickets sold = 356

Child tickets sold = 144

Step-by-step explanation:

Given information:

Define the variables:

Create two equations from the given information:

[tex]\textsf{Equation 1}: \quad x + y = 500[/tex]

[tex]\textsf{Equation 2}: \quad 7.25x+4y=3157[/tex]

Rewrite Equation 1 to make y the subject:

[tex]\implies y=500-x[/tex]

Substitute this into Equation 2 and solve for x:

[tex]\implies 7.25x+4(500-x)=3157[/tex]

[tex]\implies 7.25x+2000-4x=3157[/tex]

[tex]\implies 3.25x+2000=3157[/tex]

Answer:

Step-by-step explanation:

You want to find the number of dimes (x) and the number of quarters (y) in 19 coins that have a total value of $3.55.

Using the given variables, we can write two equations. One is for the number of coins; the other is for their value.

  x + y = 19 . . . . . . . . . . . number of coins

  10x +25y = 355 . . . . . value in cents

It usually works well to solve an equation involving the highest-value coin. That means we want to eliminate the x-variable. Using the first equation, we can write ...

  x = 19 -y

Substituting into the second equation, we get ...

  10(19 -y) +25y = 355

  190 +15y = 355 . . . simplify

  15y = 165 . . . . . . . subtract 190

  y = 11 . . . . . . . . . . divide by 15

  x = 19 -11 = 8

The number of dimes is 8.

The number of quarters is 11.

__

Alternate solution

The average coin value is 355/19 = 18 13/19 cents. The proportion of the highest-value coins is the ratio of the difference between this value and the lowest value, divided by the difference in values.

  proportion of quarters = (18 13/19 -10)/(25 -10) = (8 13/19)/15 = (165/19)/15

  proportion of quarters = 11/19

Multiplying this by the number of coins (19) gives the number of quarters:

  (11/19)×19 = 11 . . . . quarters

You may recognize some similarities to the above solution.
