[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.

4. 4a=b
a=1/4b
(I think 1/4b is the answer) hope this helps :)
Answer:
a=5b-3a-4b
Step-by-step explanation:
We first need to move all terms that do not contain a to the right side of the equation. We cancel terms on the left side by adding -4b to both sides of the equation. a+4b-4b=5b-3a-4b

A $40,000 car depreciates in value about 18% per year for the life of the car. Determine the value of the car after 7,8, and 9 years. What is the rate of decay?
Answers
Answer:
Value after:
7 years = $9971.42
8 years = $8176.56
9 years = $6704.78
Rate of decay = 18%
Step-by-step explanation:
A $40,000 car depreciates in value about 18% per year for the life of the car.
Determine the value of the car after 7,8, and 9 years. What is the rate of decay?
The formula for Depreciation is
FV = PV( 1 - r)^t
Where
FV = Future value
PV = Present value = $40,000
r = Depreciation rate = 18% = 0.18
t = time in years
a) After 7 years
$40,000 (1 - 0.18)⁷
= $9971.4188227
= $9971.42
b) After 8 years
$40,000 (1 - 0.18)⁸
= $8176.5634346
= $8176.56
c) After 9 years
$40,000 (1 - 0.18)⁹
= $6704.7820164
≈ $6704.78
= $9971.42
The Rate of decay = 18%

Simplifying
xy + -9z = 4
Solving
xy + -9z = 4
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '9z' to each side of the equation.
xy + -9z + 9z = 4 + 9z
Combine like terms: -9z + 9z = 0
xy + 0 = 4 + 9z
xy = 4 + 9z
Divide each side by 'y'.
x = 4y-1 + 9y-1z
Simplifying
x = 4y-1 + 9y-1z

about how many times would you expect it to land on blue?
Answers
Answer:
A) 60
B) 72/300
C) 150
Step-by-step explanation:
A) P(green) = ⅕
⅕ × 300 = 60
B) purple: 72
45+37+52+94+72 = 300
Therefore, 72/300
C) 1000 × (45/300)
150
a, The number of times is 60.
b. The probability for landing should be [tex]72/300[/tex]
c. The number of times is 150.
Calculation of the number of times and probability:Since
a. The spinner shown is spun 300 times
and, the probability of green should be like [tex]1/5[/tex]
So here one-fifth of 300 should be 60.
b. The probability is
First the total be like
= 45+37+52+94+72
= 300
Now the probability is
= [tex]72/300[/tex]
C) The number of times should be
[tex]= 1000 * (45/300)[/tex]
= 150

Maya makes trail mix by combining 1/2 cup of mixed nuts, 1/4 cup of dried fruit, and 1/8 cup of chocolate morsels. What is the total amount of ingredients in her trail mix? Explain how you solved the problem.
Answers
Answer:
7/8 of ingredients
Step-by-step explanation:
To calculate the amount of ingredients in Maya's trail mix, we should first come up with a common denominator to convert all the fractions to.
Our LCD here could be 8, because 8 is divisible by 2 and 4, our other denominators.
1/8 stays as 1/8.
1/2 = 4/8
since 1 x 4 = 4 and 2 x 4 = 8
1/4 = 2/8
since 1 x 2 = 2 and 4 x 2 = 8
1/8 + 4/8 + 2/8 gets us 7/8.
(( I assume you are looking for the total amount in fraction form ))
