Answer:
1
Step-by-step explanation:
6x - ( 3x + 2) = 1
6x - 3x - 2 = 1
3x = 1 + 2
3x = 3
x = 3 / 3
x = 1

A new car is purchased for 24600 dollars. The value of the car depreciates at 5.5% per year. To the nearest year, how long will it be until the value of the car is 11300 dollars?
Answer:
The number of years until the value of the car is 11300 dollars is 9 years.
Step-by-step explanation:
This can be calculated using the following formula:
Value of the Car = Purchase cost - (Annual depreciation expenses * N) ........ (1)
Where;
N = Number of years until the value of the car is 11300 dollars
Purchase cost = $24,600
Annual depreciation rate = 5.5%
Annual depreciation expenses = $24,600 * 5.5% = $1,353
Value of the car = $11,300
Substituting the value into equation (1) and solve for N, we have:
$11,300 = $24,000 - ($1,353 * N)
$1,353 * N = $24,000 - $11,300
$1,353 * N = $12,700
N = $12,700 / $1,353
N = 9.38654841093865
Rounding to the nearest year as required by the question, we have:
N = 9
Therefore, the number of years until the value of the car is 11300 dollars is 9 years.

When in-person, I love celebrating holidays with my students, including Halloween and Valentine's Day. Valentine's Day, especially, is really fun because I get to bring in candy and write little notes to all of my students. Every year, I spend about $50 on Valentine's Day for my students in order to buy bags of candy and little valentines. Every bag of candy costs $5, and every bundle of valentines costs $2. Because the bags of candy come with a lot more than the bundle of valentines, the number of bundles of valentines I buy is 4 more than the number of bags of candy I buy.

Basil was shown this enlargement, and he was asked to find the perimeter of the enlarged shape. His work is shown below.
The question is incomplete. The complete question is :
Basil was shown this enlargement, and he was asked to find the perimeter of the enlarged shape. His work is shown below.
Where, if any, did Basil first make a mistake in his work?
Solution :
Not -- Basil did not make any mistakes in his work. He found out the perimeter of an enlarged shape.
Perimeter is the total measure of the outer lining or the total outer length of the body or the shape. For different shapes, the perimeters will be different. Basil measure the outer length of the body and found out the perimeter.

Madeline is going to invest in an account paying an interest rate of 4.4% compounded
annually. How much would Madeline need to invest, to the nearest ten dollars, for
the value of the account to reach $16,600 in 12 years?
Answer:
$9540
Step-by-step explanation:
A = P(1 + r)^t
16600 = P(1.044)^12
P = 16600/(1.044)^12
P = $9,543.64

A line is parallel to y = 3x + 5 and
intersects the point (-2, 6). What is
the equation of this parallel line?
Start by entering this into point-slope form.
y- [?] = [](x
](x-[]).
Answer:
Im not like 100% sure but i think you answer is
y-6=3[x-(-2)]
y=6+3x+6
y=3x+12
And i believe that this is parallel to y
Answer:
y = 3x + 12Step-by-step explanation:
Parallel lines have same slope
Given line
y = 3x + 5The line that passes through (-2, 6) and with the slope of 3 is:
y - y₁ = m(x - x₁)y - 6 = 3(x - (-2))y - 6 = 3(x + 2)Convert the equation into slope-intercept form:
y - 6 = 3x + 6y = 3x + 6 + 6y = 3x + 12what is 7.25-6.17=? in subtracting decimals

the total price of a shirt and a cap is $11. If the price of the shirt was doubled and the price of the cap was 3 times the original price, the total price of a shirt and cap is $25. what is the price of a shirt and a cap?
Answer:
25$
Step-by-step explanation:
it says "the total price of a shirt and cap is $25."
Answer:
Price of a shirt= $8
Price of a cap= $3
Step-by-step explanation:
Let the original price of a shirt and a cap be $s and $c respectively.
From the first sentence:
s +c= 11 -----(1)
From the second sentence:
2s +3c= 25 -----(2)
From (1):
s= 11 -c -----(3)
Substitute (3) into (2):
2(11 -c) +3c= 25
Expand:
22 -2c +3c= 25
Simplify:
22 +c= 25
Minus 22 on both sides:
c= 25 -22
c= 3
Substitute c= 3 into (3):
s= 11 -3
s= 8
Thus, the prices of a shirt and a cap are $8 and $3 respectively.

Answer:
y = 03
Step-by-step explanation:
3(y+8) = 30
3y+24=30
3y=06
y = 06/2
y = 03
2y - 6y = 30
-4y = 30

What is an equation of the line that passes through the points (2, -6)(2,−6) and (1, -1)(1,−1)? Put your answer in fully reduced form.
Answer:
y= -5x+4
Step-by-step explanation:
I'm not sure why you wrote the coordinates twice so I'm going to assume you want the equation of a line that passes through (2, -6) (1, -1)
we want our equation to look like this
y=mx+b
Let's start by finding the slope
we can do that with the following equation
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\frac{-1-(-6)}{1-2}\\\frac{5}{-1}=-5[/tex]
which means we have
y= -5x+b
we just need b now
we can solve that by plugging in a coordinate
we know that when x= 2 y= -6
so
-6= -5(2)+B
solve for b
-6= -10+b
4=b
Which means our equation is
y= -5x+4
