Answer:

David made $18

Step-by-step explanation:

Leslie made $10. This means that you take 46-10=36

Chen-Chen made twice as much as David so 36/2=18 So Chen made $9.

David- 36-18= 18 So, David made 18 dollars.

In this mathematics problem, David, Chen, and Leslie together raised $46, with Leslie raising $10. Given that Chen raised twice as much as David, we can represent David's earnings as 'x' and Chen's as '2x'. By solving the resulting equation 3x = $36, we find that David raised $12.

To find out how much David made in the walk-a-thon, we need to break down the information given. We know that all three individuals together made $46, with Leslie making $10. So, David and Chen together made $46 - $10 = $36. But we are also told that Chen made twice as much as David. If we represent David's earnings as 'x', then Chen's earnings would be '2x'. Therefore, 2x (Chen's earnings) + x (David's earnings) equals $36.

Adding 2x and x gives 3x, so the equation to solve is 3x = $36. To solve for 'x', divide both sides of the equation by 3. This gives x = $36 / 3, so David's earnings, represented by 'x', is $12.

Answer:

8/5-12x.

Step-by-step explanation:

To distribute, you simply need to multiply each of the terms inside of the parenthesis by -4. This will give you:

=-4([tex]\frac{-2}{5}[/tex])-4(3x)

Answer:

X is 8

Step-by-step explanation:

[tex]100^{2} =6^{2} +x^{2}[/tex]

[tex]x=8[/tex]

Answer:

8

Step-by-step explanation:

This is a right triangle, and we know this because of the little square in the corner. Therefore, we can use the Pythagorean theorem.

a^2+b^2=c^2

a and b are the legs, and c is the hypotenuse.

We know the 6 and the unknown side are the legs, since they form the right angle. We also know that 10 is the hypotenuse, since it is opposite the right angle.

6^2+b^2=10^2

Evaluate the exponents

36+b^2=100

Now, we need to solve for b. To do this, we need to get by itself. First, subtract 36 from both sides

36-36+b^2=100-36

b^2=64

Take the square root of both sides

[tex]\sqrt{b^2}=\sqrt{64}[/tex]

b=8

So, the the unknown side is 8

Answer:

B= -40

Step-by-step explanation:

So a right triangle has to = 180

So we write the given, which 124+99

we are trying to get 180 so lets subtract that by the equation, 180-124+99

180-(124+99)

12+99=223

180-223

=-43

But in your case it has to be rounded to the nearest tenth

So the answer is -40

Answer:

Top right.

Step-by-step explanation:

For it to be an acute triangle, none of the angles can be greater or equal to 90°.

In the case of the top right triangle, none of them are:

51°, 58° , 71°

The definition of a scalene triangle, is that none of the sides must have the same measurements (no sides are congruent). This is true, all measurements are different:

8.3 ft, 9 ft, 10 ft

Top Right choice is your answer.

Answer:

40 and a half feet

Step-by-step explanation:

1 meter=3 feet

13.5m=40.5f

The runner will run about 40.5 ft

A unit conversion expresses the same property as a different unit of measurement.

For instance, time can be expressed in minutes instead of hours, while distance can be converted from miles to kilometers, or feet, or any other measure of length.

Given that, a football player runs 13 1/2 yards we need to find the that, how many feet does he run,

Since,

1 meter = 3 feet

Therefore,

13.5 m = 13.5 x 3 ft

= 40.5 ft

Hence, the runner will run about 40.5 ft

Answer:

Option D. $29,647

Step-by-step explanation:

The following were obtained from the question:

Present value = $75,000

Rate of depreciation (R) = 6%

Time (t) = 15 years

Amount after 15 years =?

Since the worth of the tractor is depreciating, we shall apply the following formula to obtain the worth after 15 years:

Amount = present value x (1 – R)^t

Amount = $75000 x (1 – 6%)^15

Amount = $75000 x (1 – 0.06)^15

Amount = $75000 x (0.94)^15

Amount = $29647

Therefore, the value of the tractor after 15 years is $29647

4.583 + 2.333 = 6.916 = 7(to the nearest whole number)

An equation is formed of two equal expressions. The distance between Traci and her home after 12 hours is 540 miles.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given that the linear equation y=45x describes how far from home Traci is as she drives from San Francisco to Dawson. where x represents the number of hours and y represents the number of miles.

Therefore, the distance covered by Traci in 12 hours is,

y = 45x

y = 45(12)

y = 540 miles

Hence, the distance between Traci and her home after 12 hours is 540 miles.

Answer:

A = 60

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles

119 = 3y+14  + 4y

Combine like terms

119 = 7y+14

Subtract 14 from each side

119-14 = 7y+14-14

105 = 7y

Divide each side by 7

105/7 = 7y/7

15 = y

We want to find Angle A

A = 4y

A = 4*15

A = 60
