I Need To Find The Value Of X

Answers

Answer 1

Answer:

x = 2

Step-by-step explanation:

This is an isosceles triangle, which means at least two sides are equal.

Set x + 3 equal to 3x-1 and solve for x.

x + 3 = 3x -  1 --- subtract x and add 1 to opposite sides.

4 = 2x --- divide 2 to each side.

2 = x

Answers

Answer:

a person can work out 50% of the maximum (50% of 194 is 97) and 85% of the maximum (85% of 194 is 164.9). This means that the target heart rate for a 20-year-old is approximately 97–165 bpm.

Ella swims four times a week at her club's pool. She swims the same number of laps on Monday, Wednesday, and Friday, and 15 laps on Saturday. She swims a total of 51 laps each week. Write an equation for the problem.

Answers

Answer:

Equation for the problem

3x + 15 = 51 laps

Hence

She swims on

Monday: 12 laps

Wednesday : 12 laps

Friday = 12 laps

Step-by-step explanation:

Ella swims four times a week at her club's pool.

We are told that:

She swims the same number of laps on Monday, Wednesday, and Friday.

Hence, the number rod times that she swims on Monday, Wednesday and Friday is represented by x

Also, she swims 15 laps on Saturday. She swims a total of 51 laps each week. Equation for the problem

= x + x + x + 15 = 51 laps

3x + 15 = 51 laps

Hence

3x = 51 - 15

3x = 36

x = 36/3

x = 12 laps

Therefore, She swims on:

Monday: 12 laps

Wednesday : 12 laps

Friday = 12 laps

Veronica bought 20 bags of candy for a school dance. The first 5 bags cost $1.79 each. The rest of the bags cost $1.19 each.

How much did Veronica spend on candy?
A. 8.95
B. 17.90
C. 26.80
D. 35.80

Answers

Answer:

Your answer is C. 26.8

Step-by-step explanation:

5 × 1.79 = 8.95

15 × 1.19 = 17.85

8.95 + 17.85 = 26.8

Answer:  C ($26.80)

Step-by-step explanation:

This is a multiplication problem.

The first 5 bags of candy cost $1.79 each, so we multiply the cost by the amount of bags that we bought for that price:

5 * 1.79 = $8.95

The rest of the bags cost $1.19 each, so we need to multiply this number by some value. To find this value, we need to know how many bags we have left. We already bought 5, and we bought a total of 20, so we need to buy:

20 - 5 = 15 bags

Multiplying the cost for the rest of the bags (1.19) by the amount of bags we need to buy still (15), we get:

15 * 1.19 = $17.85

Now we know what the cost of the first 5 bags (8.95), and we know the cost of the 15 other bags (17.85). To find the total amount of money Veronica spent, we can just add these two values together.

8.95 + 17.85 = $26.80

This total cost is shown in answer C, so that is the answer.

Flying against the wind, a jet travels 2480 miles in 4 hours. Flying with the wind, the same jet travels 7040 miles in 8 hours. What is the rate of the jet in still air and what is the rate of the wind?

Answers

Answer:

The speed of jet in still air is 750 miles per hour and speed of wind is 130 miles per hour.

Step-by-step explanation:

Given that:

Distance traveled by jet against the wind = 2480 miles in 4 hours

Combined speed = [tex]\frac{Distance}{Time}[/tex] = [tex]\frac{2480}{4}[/tex]

Combined speed = 620 miles per hour

Distance traveled with wind = 7040 miles in 8 hours

Combined speed = [tex]\frac{7040}{8}[/tex]

Combined speed = 880

Let,

Speed of jet = x

Speed of wind = y

When jet travels against the wind, the speed will be subtracted

x-y=620      Eqn 1

When jet travels with the wind, the speed will be added

x+y=880     Eqn 2

Adding Eqn 1 and 2

(x-y)+(x+y)=620+880

x-y+x+y=1500

2x=1500

Dividing both sides by 2

[tex]\frac{2x}{2}=\frac{1500}{2}\\x=750[/tex]

Putting x=750 in Eqn 2

750+y=880

y=880-750

y=130

Hence,

The speed of jet in still air is 750 miles per hour and speed of wind is 130 miles per hour.

In the given equation, k is a constant. If the equation has no solution, what is the value of k?

Answers

Answer:

0

Step-by-step explanation:

The value of constant 'k' will be [tex]\frac{1}{3}[/tex].

Given equation in the question is,

[tex]\frac{1}{3}\times (x-k)=kx[/tex]

Further solve the expression for the solution of the equation.

[tex]\frac{3}{3}\times (x-k)=3kx[/tex]

[tex](x-k)=3kx[/tex]

[tex]x-3kx-k=3kx-3kx[/tex]

[tex]x-3kx-k=0[/tex]

[tex]x(1-3k)=k[/tex]

[tex]\frac{x(1-3k)}{(1-3k)}=\frac{3kx}{1-3k}[/tex]

[tex]x=\frac{3kx}{(1-3k)}[/tex]

Since, equation has no value, denominator will be zero.

[tex]1-3k=0[/tex]

[tex]1=3k[/tex]

[tex]k=\frac{1}{3}[/tex]

     Therefore, Option (D) will be the correct option.

It is clear from the graph,

The value of x=-6 at y=0.

Thus, x=-6 is the zero of g.

Step-by-step explanation:

A zero of the linear function 'g' on the graph of a linear function can be observed where the 'y-value' is zero.

In other words,

A point where the line tends to cross the x-axis is called the x-intercept.x-intercept can be observed by setting the y=0 and determining the value of x at y=0

It is clear from the graph,

The value of x=-6 at y=0.

Thus, x=-6 is the zero of g.

Carissa earns $450 per week for a 40 hour work week plus $16.83 per hour for each hour of overtime after 40 hours. Write an equation that would be used to determine her weekly wages where, W, is her wages and, V, is the number of overtime hours worked.

Answers

Answer:

W = 450 + 16.83V

Step-by-step explanation:

For 40 hours Carissa

earning = $450

earning for 1 hour of over time = $16.83

multiplying both side by V

earning for v hour of over time = $16.83*V = $16.83V

weekly wage(W) = earning for 40 hours + earning for V hour of over time

W = 450 + 16.83V

Thus equation will be as given below for weekly earning

Doors for the small cabinets are 19.5 inches long. Doors for the large cabinets are 2.7 times as long as the doors for the small cabinets. How many large doors can be cut from a board that is 10 feet long?

Answers

Answer:

2 Large doors

Step-by-step explanation:

Step 1

We convert 10 feet to inches

1 foot = 12 inches

10 feet = x

Cross Multiply

x = 10 × 12 inches

x = 120 inches

Doors for the small cabinets are 19.5 inches long. Doors for the large cabinets are 2.7 times as long as the doors for the small cabinets.

The length of Large doors = 2.7 × 19.5 inches

= 52.65 inches

Hence, the number of large doors can be cut from a board that is 10 feet long(120 inches long) is

= 120 inches/52.65 inches

= 2.2792022792 doors

Approximately = 2.3 doors

However, the number as to be in whole number, hence, only 2 Large doors can be cut from a board that is 10 feet long(120 inches long)
