Answer:
[tex]\boxed {\boxed {\sf 1. \ 20 }}[/tex]
Step-by-step explanation:
An equilateral triangle has 3 equal sides and angles. Remember that equilateral sounds like equal.
The interior angles of a triangle must equal 180 degrees.
All 3 angles are the same.180/3= 60 All 3 angles in an equilateral triangle equal 60 degrees.The question tells us the angle is equal to (4x-20).
∠= 60°∠= (4x-20)°So, by substitution, we can set 60 and (4x-20) equal to each other.
[tex]60=4x-20[/tex]
Now, solve for x by isolating the variable on one side of the equation.
20 is being subtracted from 4x and the inverse operation of subtraction is addition. Add 20 to both sides of the equation.
[tex]20+60=4x-20+20 \\ 20+60=4x\\80=4x[/tex]
x is being multiplied by 4. The inverse operation of multiplication is division. Divide both sides of the equation by 4.
[tex]\frac{80}{4}=\frac{4x}{4}[/tex]
[tex]\frac{80}{4}=x \\\ 20=x[/tex]
x is equal to 20 and choice 1 is correct.
Simplify the expression by combining like terms.
3.6x+5.9−2.2−1.7x
Enter your answer as an expression, like this: 42x+53

Answer:
Student B
Step-by-step explanation:
Proportional relationship means that it follows a certain pattern or is constant.
Student B was the only relationship to be constant as it goes by multiples of 6.
Ex. 6, 12, 18, 24, 30.
Answer:
Student B
Step-by-step explanation:
Student B's wages increase by 6 each time, but Students A, C, and D do not steadily increase. The steady increase of 6 for Student B is what makes their wages proportional.
what is 10.26 with 8% tax
Answer:
$11.08 to the nearest penny
Step-by-step explanation:
So I do it like
10.26 is 100 percent
We’re adding 8 percent so technically multiplying by 108
SO 10.26*108 is 11.08 to the nearest penny
It so much easier, easy 1 step

April wants to multiply 6 and 42 using the distributive property. Which of the following number sentences shows how
she could do it?
06x42 = 42 x6
06x(40+2) =(6x 40) + 2
O(6x42) x1=6x (42 ×1)
06x(40 +2) = (6x 4o) + (6
2)
Answer:
I'm pretty sure the answer is the last one;
6 x (40+2) = (6 x 40) + (6 x 2)
The 6 is distributed to the 40 and the 2

please find the area of this irregular shape
Answer: 10 sq units
Step-by-step explanation:
Area of triangle: 1/2 x b x h
1/2 x 2 x 2 = 2
Area of the left triangle is 2 sq units
1/2 x 4 x 2 = 4
Area of the right triangle is 4 sq units
Area of square: l x w
2 x 2 = 4
Area of square is 4 sq units
Area of figure: A of square + A of r tri. + A of left tri.
4 + 4 + 2 = 10
The area of the figure is 10 sq units.

If 7 workers take 500 hours to finish a project, how long will it take 14 workers to complete the same project?
Answer:
250 hours
Step-by-step explanation: increasing the number of workers will make the project go faster. So they multiplied the 7 by 2 so now there are 14 workers so then the time it'll take to finish the project would be cut in half because now they have twice the numbers of workers. correct me if I'm wrong

Error Analysis A contractor purchases 7 dozen pairs of padded work gloves for $97.44. He
incorrectly calculates the unit price as $13.92 per pair for the expense report. What is the correct
unit price? What is the error?
The correct unit price is $
per pair
Answer:
Unit price = $1.16
His error was he divided $97.44 by 7 when in fact he should have divided 97.44 by 84
Step-by-step explanation:
7 dozen pairs
1 dozen = 12
7×12 = 84
97.44 ÷ 84 = 1.16
