Answer: 9
Step-by-step explanation:
The company has a total of 3 big trucks.
What is algebraic expression?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.

choose yes or no to tell if the fraction 2/9 will make each equation true
81 x =18
900 x = 200
72 x =16
450x = 100
Answer:
yes
Step-by-step explanation:
to see if 2/9 will make each equation true, you replace 'x' with 2/9, so let us do just that-
81*2/9=18
900*2/9=200
72*2/9=16
72*2/9=16
450*2/9=100
now, seeing as how every answer we've gotten matches the answers of the algebraic equations, the answer is yes 2/9 does make each equation true

Pheobe had 6 keys. She paid with a $10.00 bill and received $3.28 change. How much did it cost to have EACH key made
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.

A $40 shirt now selling for $28 is discounted by what percent? A. 20% B. 30% C. 40% D. 60 %
Answer:
c
Step-by-step explanation:
The percent of discount on the shirt will be 30%.
What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol '%' is used to symbolize it.
The percentage is given as,
Percentage (P) = [Initial value - Final value] / Initial value x 100
A $40 shirt now selling for $28.
Then the percent of discount on the shirt will be
The final value of the shirt is $18 and the initial value of the shirt is $40.
Percentage (P) = [(40 - 28) / 40] x 100
Percentage (P) = [12 / 40] x 100
Percentage (P) = 0.30 x 100
Percentage (P) = 30%
Thus, the percent of discount on the shirt will be 30%.

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.

Answer:
M1= 35° M2=30°
Step-by-step explanation:
At the point where the two triangle meet, the north angle is 115°, so the south one will be 115°, because they're alternate angles. This means that to get the other two angles left, you must subtract the two angles that weren't in the triangles on that point = 360° - (115 x 2) = 130°. 130° is the total of the two angles on the point in the two triangles. Then you just subtract the two angles you have for each triangle from 180° to get the last two angles
