Bill started with 15 pairs of shoes. On average, Bill buys 7 new pairs of shoes every 2 months.
Answer:
y = 3.5x + 15Step-by-step explanation:
Number of months is x, and number of pairs of shoes after each month is y.
7 new pairs of shoes every 2 months means that after each month:
y = 7/2 x
We need to add the 15 pairs from start.
y = 3.5x + 15

Cory went to Kohl's and bought 10 pairs of socks for $2.50 each and 3 pairs of shoes for d dollars each. He spent a total of $135.97. Write an equation to find the cost of one pair of shoes.
Answer:
[tex]25+3d=135.97[/tex]
Step-by-step explanation:
Number of pairs of socks = 10
Cost of each pair of socks = $2.50
Cost of 10 pairs of socks = 10 × 2.50 = $25
Number of pairs of shoes = 3
Cost of each pair of shoes = $d
Cost of d pair of shoes = $3d
Therefore,
[tex]25+3d=135.97[/tex]
So,
Equation is [tex]25+3d=135.97[/tex]

The simplified expression 1/3 * 1/3 * 1/3 as exponents is 1/3³
How to simplify the expression as exponentsFrom the question, we have the following parameters that can be used in our computation:
1/3 * 1/3 * 1/3
Express as equation
Result = 1/3 * 1/3 * 1/3
Apply the law of indices
So, we have the following representation
1/3 * 1/3 * 1/3 = 1/3¹⁺¹⁺¹
Evaluate the sum
1/3 * 1/3 * 1/3 = 1/3³
Using the above as a guide, we have the following:
The expression cannot be further simplified
Hence, the simplified expression is 1/3³

find the factors of (2y+1/3)^2- (3y+1/2)^2 pls reply fast!!!
Here, thankyou!!!!!!!
Answer:
Perimeter of i - 22CM
Area of i - 13CM^2
Perimeter of ii -38CM
Area of ii -66CM^2
Perimeter of iii -30CM
Area of iii- 42CM^2
Perimeter of iv - 50CM
Area of iv- 126CM^2
Step-by-step explanation:
SHAPE I:
PERIMETER = S + S + S + S + S +S
= 7 + 1 + 5 +3 +4 +2
= 22CM
AREA = Part a - 4 * 2 = 8cm^2 part B - 5 *1 = 5cm^2
Total = 8 + 5 = 13cm^2
SHAPE II:
PERIMETER = S + S + S + S + S +S
= 4 + 4 +5 + 6 + 9 + 10
= 38 CM
AREA = Part a - 5 * 10 = 50 cm^2 part B - 4 *4 =16 cm^2
Total = 50+16 =66 cm^2
SHAPE III:
PERIMETER = S + S + S + S + S +S
= 9 + 2 + 3 + 4 + 6 + 6
= 30CM
AREA = Part a - 6 * 6 = 42cm^2 part B - 3 * 2= 6cm^2
Total = 36 + 6 =42 cm^2
SHAPE IV:
PERIMETER = S + S + S + S + S +S
= 9 + 10 + 4 + 6 + 6 + 15
= 50 CM
AREA = Part a -15 * 6 = 90 cm^2 part B - 9 *4 = 36cm^2
Total = 90 + 36 = 126cm^2

Verify that f and g are inverses functions using composition , show your steps
Answer: We can conclude that f(x) and g(x) are not inverses.
Step-by-step explanation:
If we have two functions:
f(x) and g(x)
These functions are inverses if:
f( g(x) ) = x
g( f(x) ) = x
In this case, we have:
f(x) = 12*x - 12
g(x) = (1/12)*x - 1
Now we need to check the compositions:
f( g(x) ) = 12*g(x) - 12 = 12*( (1/12)*x - 1) - 12 = (x - 12) - 12 = x - 24
and:
g( f(x)) = (1/12)*f(x) - 1 = (1/12)*(12*x - 12) - 1 = 12*x/12 - 12/12 - 1 = x - 1 - 1 = x - 2
In both cases, we can see that:
f( g(x) ) ≠ x
and:
g( f(x) ) ≠ x
Then we can conclude that f(x) and g(x) are not inverses functions.
C) Which of the items had the greatest increase in sales over the 3 years ? Give a reason for your answer
Answer: Tablets because they increase in sales by 467%
Step-by-step explanation:
The item with the greatest increase is the one that has the highest percentage increase in the 3 years.
Each box represents 20 units sold.
Desktop Computers:
= (2017 sales - 2015 sales) / 2015 sales * 100%
= (160 - 100) / 100 * 100%
= 60%
Laptops:
= (280 - 160) / 160 * 100%
= 75%
Tablets:
= (340 - 60) / 60 * 100%
= 467%

How many ounces of a 19% alcohol solution and a 37% alcohol solution must be combined to obtain 90 ounces of a 24% solution
Answer:
19% alcohol solution = 65 ounces
37% alcohol solution = 25 ounces
Step-by-step explanation:
Let
19% alcohol solution = x
37% alcohol solution = y
x + y = 90 (1)
0.19x + 0.37y = 90*0.24
0.19x + 0.37y = 21.60 (2)
from (1)
x = 90 - y
Substitute into (2)
0.19x + 0.37y = 21.60
0.19(90-y) + 0.37y = 21.60
17.1 - 0.19y + 0.37y = 21.60
- 0.19y + 0.37y = 21.60 - 17.1
0.18y = 4.5
y = 4.5/0.18
y = 25 ounces
x + y = 90 (1)
x + 25 = 90
x = 90 - 25
x = 65 ounces

How do you do 20/4 divided by 8/9 and put it in simplest form?
Answer:
45/8, or 5.625
Step-by-step explanation:
20/4 is simplified to 5/1.
5/1 divided by 8/9
5/1 * 9/8
45/8
simplified to 5.625
Answer:
45/8 or 5 5/6.
Step-by-step explanation:
20/4 / 8/9 We invert the second fraction and multiply:
= 20/4 * 9/8
= 180 / 32
= 45/8
= 5 5/8.

Pleaseee helppp answer correctly !!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!!
Answer:
let the opposite angle of 44 be x
and let opposite angle of z be y
44+52 + x=180( by sum of all angle is 180°)
96+x=180
x= 180-96
x=84
y+x=180 ( linear pair angle)
y+84=180
y=180-84
y=96
now the y, z,40 are triangle.
y+z+40=180( by sum of all angle)
96+z+40=180
z+136=180
z=180-136
z=44
A bus that is traveling north at 48 km/h slows to a stop to pick up passengers. It then begins moving again. At the next corner, it turns to the east.
a. Identify the speed of the bus.
b. Identify one example of the velocity of the bus.
c. Identify each group of words or phrases that describe acceleration of the bus.
Answer:
A
Step-by-step explanation:
In 120 seconds, the speed of a bus travelling on a smooth road increases from 8 m/s to 32 m/s. This technique uses the bus's potential energy.
Explain about the velocity?
Velocity is the rate of travel in a specific direction and adds direction to speed. Divide the distance travelled by the time it took to travel that distance, then add direction to determine the velocity. Velocity is zero if one's position doesn't change.
By dividing the amount of time it took the object to go a certain distance by the overall distance, one can calculate the object's initial velocity. V is the velocity, d is the distance, and t is the time in the equation V = d/t.
Velocity can be defined as the rate at which something moves in a specific direction as the speed of a car driving north on a highway or the pace at which a rocket takes off.

Answer:
3/8 room
Step-by-step explanation:
Given data
We are told that 2 rolls of wire are needed to wire 1 room
Hence if 1 room needs 2 rolls
x rooms will need 3/4 rolls
cross multiply we have
2x= 3/4
Multiply both sides by 1/2
