Answer: Let's solve for x.
2x−10y=10
Step 1: Add 10y to both sides.
2x−10y+10y=10+10y
2x=10y+10
Step 2: Divide both sides by 2.
2x
2
=
10y+10

Step-by-step explanation:
Let's solve for s.
sx+9y=9
Step 1: Add -9y to both sides.
sx+9y+−9y=9+−9y
sx=−9y+9
Step 2: Divide both sides by x.

Which table shows a proportional relationship between x and y?
A,x 3 6 8 10 y 12 15 18 20
B,x 1 2 7 8 y 0.5 1 3.5 4
C,x 3 7.5 15 20 y 1 2.5 4 6
D,x 2 3 4 5 y 7 9 11 13
Answer:
Table B shows a proportional relationship between x and y
Step-by-step explanation:
x y
1 0.5
2 1
7 3.5
8 4
It is clear from the table that y varies directly with x.
Using the formula
y ∝ x
y=kx
Where k is the constant of proportionality
In order to find 'k',
k=y/x
Putting the values of x and y from the given table to determine the constant of proportionality
For (1, 0.5)
k=0.5/1=0.5
For (2, 1)
k = 1/2 = 0.5
For (7, 3.5)
k = 3.5/7 = 0.5
For (8, 4)
k = 4/8 = 0.5
As the value of the constant of proportionality 'k' is the same.
Thus, table B shows a proportional relationship between x and y

Juan paid $42 in taxi fare from the hotel to the airport. The cab charged a $7 initial fee plus $2.50 for each additional mile. How many miles was it from the hotel to the airport?
Answer:
It was 14 miles from the hotel to the airport.
Step-by-step explanation:
From the information given, the taxi fair is equal to the initial fee plus the result of multiplying the price per mile for the number of miles, which is:
t=7+2.50x, where:
t is the taxi fair
x is the number of miles
Now, you can replace t with 42 and solve for x to find the miles:
42=7+2.50x
42-7=2.50x
35=2.50x
x=35/2.50
x=14
According to this, the answer is that it was 14 miles from the hotel to the airport.

Tina worked 5 hours and earned $100. What would happen to her wages earned if she worked for 10 hours? Explain your reasoning as it relates to direct variation.
Answer:
She would earn $200 for working 10 hours
Step-by-step explanation:
100/5= $20 per hour
10hr multiplied by $20= $200
Answer:
$200 (read below for reasoning)
Step-by-step explanation:
Since 5x2 is 10, we can double both 5 and 100 to get the amount of money Tina will earn in 5 hours. Since 100x2 is 200, Tina will earn $200 in 10 hours. In other words, her wage would double. I hope this helps!

A recipe that makes 4 dozen cookies calls for 2 eggs. Using this same recipe, how many dozens of cookies can be made with 7 eggs?
Answer:
14 dozen cookies can be made with 7 eggs
Step-by-step explanation:
I first saw that 2 goes into 7 three times (2*3= 6 eggs).
then I multiplied 4 dozen also by 3 to get 144 cookies (12 dozen).
since there was still one egg left I divided the 4 by a half and got 2 dozen.
2 dozen + 12 dozen = 14 dozen (168 cookies)

Maya has 120 caramel apples to sell. each caramel apple is covered with one topping.
1/5 of the caramel apples are covered with peanuts
13 are covered with chocolate chips
3/10 are covered with coconut the rest are covered with sprinkles.
how many caramel apples are covered with sprinkles
please help mee
Answer:
20
Step-by-step explanation:
120 = (1/5 x 120) + (1/3 x 120) + (3/10 x 120) + sprinkles
120 = 24 + 40 + 36 + sprinkles
Sprinkles = 120 - 24 - 40 - 36 = 20
This means that 20 caramel apples are covered with sprinkles

The skateboard rita would like to buy a car $6 less than three times the amount you had sick she has saved the skateboard cost $69 how much money does rita have saved
Answer:
$25
Step-by-step explanation:
Let the total amount saved by Rita be represented by x.
Since the amount is x, and her savings is in such away that 6 is less than three times of it.
i.e 3x-6........ 1
Then the above will be equal to 69
3x-6 = 69
3x = 69+6
3x = 75
x = 75/3
X = 25
Definitely, she has saved $25

Aisha and Carolina each sketch a graph of the linear equation y=− 3 4x+2. Aisha uses the equation y= −3 4x+2 to sketch the graph, and Carolina uses the equation y= 3 −4x+2. a. Explain how this leads them to use different steps to construct their graphs. b. Will the two graphs look the same? Explain. a. Choose the correct answer below.
A linear function is used to represent the equation of a straight line.
Aisha's graph has a rise of -3 and a run of 4Carolina's graph has a rise of 3 and a run of -4Both graphs would look the sameGiven
[tex]y = -\frac 34x + 2[/tex] --- Aisha
[tex]y = \frac{3}{-4}x + 2[/tex] --- Carolina
(a) How they use different step
A linear equation is represented as:
[tex]y = mx + b[/tex]
Where:
[tex]m \to[/tex] slope
[tex]b \to[/tex] y intercept
and
[tex]m = \frac{rise}{run}[/tex]
For Aisha's graph;
[tex]m = \frac{-3}{4}[/tex]
By comparison:
[tex]rise = -3[/tex]
[tex]run = 4[/tex]
This means that Aisha's graph has a rise of -3 and a run of 4
i.e. the other point used to calculate the slope is gotten by moving 3 units down and 4 units left of the y-intercept.
For Carolina's graph;
[tex]n = \frac{3}{-4}[/tex]
By comparison:
[tex]rise = 3[/tex]
[tex]run = -4[/tex]
This means that Carolina's graph has a rise of 3 and a run of -4
i.e. the other point used to calculate the slope is gotten by moving 3 units up and 4 units right of the y-intercept.
(b) Will the graph look the same?
Recall that:
[tex]y = mx + b[/tex]
[tex]m \to[/tex] slope
[tex]b \to[/tex] y intercept
For Aisha's graph
[tex]y = -\frac 34x + 2[/tex]
The slope is:
[tex]m = -\frac{3}{4}[/tex]
[tex]m = -0.75[/tex]
The y intercept is:
[tex]b = 2[/tex]
For Carolina's graph
[tex]y = \frac{3}{-4}x + 2[/tex]
The slope is:
[tex]m = \frac{3}{-4}[/tex]
[tex]m = -0.75[/tex]
The y intercept is:
[tex]b = 2[/tex]
Both equations have the same slope and the same y-intercept.
Hence, the graphs will look the same
See attachment for the graphs of their equations.
