Mr. Duncan earns 75$ a day plus 35$ for each car he sells. if c is his total earnings and x is the number of cars he sold, what is the equation

Answers

Answer: c= 35x + 75

Step-by-step explanation:

If he earns $75 then that will be the constant amount which means it will never change, plus $35 for x cars, will give us the expression 35x + 75 and that has to equal c which is his total earnings.

Answer:

c = 35x + 75

Step-by-step explanation:

Daily pay = $75Commission for each car = $35

Total earnings for x cars sold:

c = 35x + 75

Answers

Answer:

  a) no

  b) yes

  c) maybe (no)

Step-by-step explanation:

There are two versions of the triangle inequality. One requires ...

  a + b > c

for any triple of side measures a, b, c.

The other allows ...

  a + b ≥ c

which admits "triangles" that have zero height and look like line segments.

Most questions asking "do these lengths form a triangle" are concerned with the "greater than" case, and disallow the "or equal to" case.

Answer:

3x+30= 116° 2x=64°

Step-by-step explanation:

the angle below 2x is the same as 3x+20 so we know that 5x+20=180 so solve this

5x+20=180

5x=160

x=32

sub x into the angle equations

3(32)+20=116

2(32)=64

Answer:

x=32°

Step-by-step explanation:

3x+20+2x=180°(being co interior angle)

3x+2x+20=180°

5x=180-20

5x=160

x=32°

Ashley found 2 boxes of sugar in the kitchen. The green box is 1.26 kg and the red box is 1.026 kg. Which box contains more sugar?

Answers

Answer:

Answer:

Green box contains more sugar.

Step-by-step explanation:

Consider the provided information.

Ashley found 2 boxes of sugar in the kitchen.

The green box says 1.26 kg and the red box says 1.026 kg.

we need to find which box contains more sugar.

To find this we will first check the digit at ones place.

Both the digit has 1 at the ones place. So now check the digit at tenths place.

1.26 has 2 at tenths place while 1.026 has 0 at tenths place.

As we know 2 is greater than 0, thus the number 1.26 is greater than 1.026.

Hence, green box contains more sugar.

The green box has more sugar because if you convert it to pounds the red box has 2.26 pounds of sugar while the green box has 2.777825 pounds.

On a family road trip, Mr. Edwards travels 130 miles in two hours. At this rate, how many miles will he travel in 30 minutes? (watch the time on this one!) Group of answer choices

Answers

Answer:

32.5 miles in 30 minutes.

Step-by-step explanation:

There are a total of 4 - 30 minute segments in a period of two hours. Therefore, in this question, we can simply divide the total distance that Mr Edwards travelled during those two hours by the 4 segments, and that would give us the distance travelled in a single segment of 30-minutes.

130 / 4 = 32.5 miles

Finally, we can see that Mr Edwards travelled 32.5 miles in 30 minutes.

Geometry

Congruent AnglesAll angles in a triangle add up to 180°

Step-by-step explanation:

Step 1: Define

m∠D = 58°

m∠E = m∠F = x

Step 2: Set up equation

58 + x + x = 180

Step 3: Solve for x

Combine like terms:                    58 + 2x = 180Subtract 58 on both sides:          2x = 122Divide 2 on both sides:               x = 61°

In this case they are asking you for the slope which means you need to use the formula of y= mx + b where mx is the slop and b is the y intercept.

In this case the slope is 1/2 and the y intercept is 0 so your equation will read as

Y= 1/2p + 0 (you can decide whether or not to put the 0)

A clothing store is having a sale in which all T-shirts are $10. The sales tax is 5%. If Dan buys n T-shirts during this sale, the total cost of his purchase will be 10n + 0.05(10n). Interpret the meaning of 0.05(10n) in this context

Answers

Answer:

Step-by-step explanation:

Cost of 1 T-shirt = $ 10

Sales tax for 1 T-shirt = 5% * 10 = 0.05 * 10

Cost of n T-shirt = $ 10n

Sales tax for 'n' T-shirts = 0.05 * (10n)

Sales tax on  'n'  T-shirts = Sales tax for 1 T-shirt  * (Cost of n T-shirt)

Answer:

the cost of the t shirt  = 10 times the sale tax which is 5%

Jimmy purchased 15 tickets to a concert and spent $140. He purchased some children's tickets and some adult tickets. The children's tickets cost $7 each and the adult tickets cost $12 each. Write a system that represents this situation. How many of each did Jimmy purchase?​

Answers

Answer:

Jimmy purchased 8 of the children's ticket and 7 of the adult's ticket.

Step-by-step explanation:

Let c = children tickets

Let a = adult tickets

Given the following data;

Number of tickets = 15

Total amount spent = $140

Cost of each children ticket = $7

Cost of each adult ticket = $12

*Translating the word problem into an algebraic equation (system)*

For the total number of tickets;

[tex] c + a = 15 [/tex] .........equation 1

For the total amount spent;

[tex] 7c + 12a = 140[/tex] ..........equation 2

*Solving the linear equation by using the substitution method*

Making c the subject in equation 1:

[tex] c = 15 - a[/tex] .......equation 3

Substituting "c" into equation 2;

[tex] 7(15 - a) + 12a = 140 [/tex]

Simplifying the equation, we have;

[tex] 105 - 7a +12a = 140[/tex]

[tex] 105 + 5a = 140[/tex]

Rearranging the equation, we have;

[tex] 5a = 140 - 105[/tex]

[tex] 5a = 35[/tex]

[tex] a = \frac {35}{5} [/tex]

a = 5 (For the $12 adult ticket).

To find the number of children tickets;

Substituting "a" into equation 3;

[tex] c = 15 - 7[/tex]

c = 8 (For the $7 children ticket).

What is the value of x?

Answers

Answer:

x = 8

Step-by-step explanation:

recall that all internal angles of a triangle sum up to 180 deg

we are given that ∠F is a right angle = 90 deg

Simply sum all all the angles and equate the sum to 180 deg

90 + (3x+29) + (5x-3) = 180

90 + 3x+29 + 5x-3 = 180

90 + 3x+29 + 5x-3 = 180

116 + 8x = 180  (subtract 116 from both sides)

8x = 180 - 116

8x = 64  (divide both sides by 8)

x = 64/8

x = 8

I believe it is 8 since the three angles must add up to 180°
