Step-by-step explanation:

The company has a total of 3 big trucks.

An algebraic expression is a combination of terms both variables and constants. We can write the examples of algebraic expression as -

2x + 3y + 5

5x + 4y + 1

Given is that Jenny's company has 15 trucks in two different sizes. There are small trucks with 6 wheels and large trucks with 12 wheels. Her company needs to inspect the 108 wheels of all of the trucks

We can write the system of equations as -

s + b = 15

6s + 12b = 108

6(15 - b) + 12b = 108

90 - 6b + 12b = 108

18 = 6b

b = 4

Therefore, the company has a total of 3 big trucks.

A. (For Claire’s gross income) is 3,725.

B. (For Tina’s net income) is 2,100.

D. (For Jie’s net income) is 48.6, or 243/5.

Answer:

$1.12

Step-by-step explanation:

One way to solve this problem is through an algebraic equation. Set up the equation like this, [tex]10-3.28=6x[/tex]. This equation works because 3.28 is subtracted from 10, which represents how much was spent in total. Then, this is equal to 6x, which represents the total cost of six keys.

So, to solve first subtract 3.28 from 10, this gives you 6.72. Then, divide both sides by 6. This equals 1.12, which is the cost of each key.

Answer:

Gotcha!

Step-by-step explanation:

I know this is a day late and you probably have done it, but...The earnings for the first 40 hours are $9.20 x 40 = $368.00 (it’s just 368 but with unnecessary zeros, which you don’t have to add, by the way, this answer is g00gle approved.)

The rate for each after after 40 is $9.20 x 1.5 = $13.80 <— again, you could also put 13.8, since the zero is unnecessary. They both mean the same thing. 13.8 = 13.80 the difference is one has a zero and the other doesn’t.

Therefore, the amount Mr. Evans earned for the extra 1.75 hours is $16.1 (16.10),  You added the two amounts to find that Mr Evans earned $384.10

368.00 + 16.10 (also g00gle approved)

You learned that Mr. Evans earned 384.10 last week. (Or whatever answer choice that corresponds/relates to the question.

I hope this helped!

The 3rd one

This is because in the graph it’s looking for numbers 70-79 but only with 2 numbers and the 3rd is the only one that fits in the description.

Answer:

$12.50

Step-by-step explanation:

3/8 x 20/1 = 7.5

20 - 7.5 = 12.50

Jeff has $12.50 left after spending 3/8 of his money on lunch.

Two or more expressions with an Equal sign is called as Equation.

Given that Jeff had $20.

Jeff spent 3/8 of his money on lunch.

To find the money he left after spending on lunch we get by subtracting three by eight from one.

1 - 3/8

=8-3/8

= 5/8 of his money left.

To find out how much money Jeff has left, we can multiply the remaining fraction by his initial amount of money:

Intitial amount is 20

The money left is 5/8.

Multiply five by eight with twenty.

Money left = (5/8) × $20

Five divided by eight times of twenty.

=100/8

When hundred is divided by eight we get twelve point five.

= $12.50

Therefore, Jeff has $12.50 left after spending 3/8 of his money on lunch.

Answer:

I'm not sure but you can print 13 posters in 1 minute

Answer:

A: 68.25 minutes

B: 12 times

C: 42 mins and you decide this part I actually don't know. But I think it could be reasonable, after 40 times someone should get pretty good at it.

Step-by-step explanation:

a: 72 -0.75*5 = 68.25

b: M=63=72-0.75n

subtract 72 from each side: -9 = -0.75n

divide each side by -0.75: n = 12

so 12 times

c: 72 - 0.75(40) = 42 minutes. Now this could be is reasonable, but we don't know what their desert is. But 40 times is a lot of practice.

25-9= 16 so x=4

4×(3×4)+6×6 = 48+36 = 84

Answer:

Part A: The mean is 8  (count the number in the data set which is 8 then add the numbers which is 64 then divide by 64 by 8 which is 8)

Part B: Absolute Deviation= 0  

shown work for part B:      (subtract each number by the mean)

8-8+9-8+9-8+7-8+8-8+6-8+9-8+8-8=0

plz can i get Brainliest i tried my best and worked very hard

The number of storybooks owned by eight classmates is shown below: 8, 9, 9, 7, 8, 6, 9, 8. The mean is 8 and Absolute Deviation= 0.

The mean value of the data set is the ratio of the sum of the data set's values to number of values it has.

If the data set consists of values

x_1, x_2, ..., x_n

, then we get the mean value as:

[tex]\overline{x} = \dfrac{x_1 + x_2 + \cdots + x_n}{n}[/tex]

The number of storybooks owned by eight classmates is shown below:

8, 9, 9, 7, 8, 6, 9, 8

Part A:

[tex]\overline{x} = \dfrac{ 8+ 9+ 9+ 7+ 8+ 6+ 9+ 8}{8}[/tex]

Therefore, The mean is 8

Part B: Absolute Deviation= 0  

subtract each number by the mean

8-8+9-8+9-8+7-8+8-8+6-8+9-8+8-8=0

(then divide sum by mean) 0 divided by 8 = 8
