Answer:
x=-6 if y=8
Step-by-step explanation:
First, plug in 8 for y then solve:
2x+3(8)=12
2x+24=12
Next, subtract 24 from each side:
2x+24=12
2x-24=-24
2x=-12
x=-6

12 7/12
hope it helps :)
Answer: 12 7/12
4 (1/3) + 8 (1/4) (Add the whole numbers together)
= 12 [(1/3) + (1/4)] (Find the LCD and multiply the numerators and denominators by the amount that will get you the LCD*)
= 12 [(4+3)/12]
= 12 (7/12)
*LCD = 12
(1/3) · 4 = 4/12
(1/4) · 3 = 3/12

Leilani has $5.50. Her mother gives her $2.75, and her sister pays her back $1.80 that she had borrowed. Leilani goes to the store and spends $3.89. How much money does she have left?
She starts off with $5.50. Her mom gives her $2.75. ($5.50+ $2.75= $8.25 ) Her sister then pays back $1.80 which she had owed. Which is 8.25 +1.80= 10.05. She then spends $3.89. $10.05 - $3.89 = 6.16
The answer is 6.16. Lelani has $6.61 left.

Lin read for x minutes, and Elena read for 5/8 more than that. Write an expression for the number of minutes Elena read. Only use decimals in your expression.
Answer: The expression for the number of minutes Elena read. = x+0.625
Step-by-step explanation:
Given: Lin read for x minutes, and Elena read for 5/8 more than that.
Then, Elena reads = [tex]x+\dfrac58[/tex] minutes
Also, [tex]\dfrac58=0.625[/tex] [divide 5 by 8]
So expression becomes, [tex]x+0.625[/tex]
Hence, the expression for the number of minutes Elena read. = x+0.625

Step-by-step explanation:
Will has three times as much money as Luke has. Luke has $18 more than twice as much as jack has. If the boys have $315 in total, how much does each have?
Answer:
Will has $216, Luke has $72, and Jack has $27
Step-by-step explanation:
Let's form some equations.
Let W represent the amount of money that Will has
Let L represent the amount that Luke has
and Let J represent the amount that Jack has
L+W+J= $315
W=3L
L=2J+18
If we input the value of L into Will's equation, it will look like this:(replace the value of L with the equation representing L)
W=3(2J+18)
Now lets input these equations into the first equation, which will then look like this:
(2J+18)+3(2J+18)+J=315
Now that we only have one variable in the equation, we can simplify it to get
9J+72=315
and when we solve for J, we get:
J=27
we then input the value of J into the equation used to find the amount that Luke has:
L=2J+18
L=2(27)+18 to get
L= 72
and now we solve Will's equation:
W=3L
W=3(72)
W=216
So Will has $216, Luke has $72, and Jack has $27
if we add these up, we get a total of $315
Complete the equation for the horizontal line that passes through (11, 4).
Y=
Answer:
y = 4
Step-by-step explanation:
A horizontal line parallel to the x- axis has equation
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (11, 4) with y- coordinate 4 , thus
y = 4 ← equation of horizontal line
We have that from the co-ordinates given that
[tex]Y=4[/tex]
From the Question we are told that
Horizontal line that passes through (11, 4).
The co-ordinates represents the x and y
Generally the equation for the line is mathematically given as
[tex]y=mx+c[/tex]
Therefore
The equation of the

A scuba diver dove 63 feet below the ocean's surface. He then ascended 27 feet to under an underwater cave. What is the depth of the entrance of the cave?
Answer:
First, we need to define a zero in the vertical position.
Let's define the zero as the ocean's surface.
"A scuba diver dove 63 feet below the ocean's surface."
Then the scuba's position at this moment was:
P = -63ft
"He then ascended 27 feet to under an underwater cave."
The new position will be:
P = -63ft + 27ft = -36ft
And here is the entrance of the underwater cave.
Then we can conclude that the depth of the entrance of the underwater cave is 36ft deep, or that the entrance is 36ft below the ocean's surface.
Item 18 The distance between Cleveland, Ohio, and St. Louis, Missouri, is 3 miles less than 2 times the distance between St. Louis and Chicago, Illinois. Let d be the distance between St. Louis and Chicago. Which expression can you use to represent the distance between Cleveland and St. Louis?
Answer:
d = 2x-3
Step-by-step explanation:
Given that,
The distance between St. Louis and Chicago is d. We need to find the expression for the distance between Cleveland, Ohio, and St. Louis, Missouri. Let it is x. So,
ATQ,
The distance between Cleveland, Ohio, and St. Louis, Missouri, is 3 miles less than 2 times the distance between St. Louis and Chicago.
d = 2x-3
So, above is the expression for the distance between Cleveland, Ohio, and St. Louis, Missouri.

Write the point-slope form of the equation of the line that passes through the origin and has a slope of 2. Include your work in your final answer. Type your answer in the box provided to submit your solution.
Answer:
The equation of the line that passes through the origin and has a slope of 2 is y = 2x
Step-by-step explanation:
Explanation:-
The point -slope form is
[tex]y-y_{1} = m ( x - x_{1} )[/tex]
Given origin O( 0,0) and slope m = 2
[tex]y-0= 2 ( x - 0 )[/tex]
y = 2 x
∴ The equation of the line that passes through the origin and has a slope of 2 is
y = 2x
Carnival T charges an entrance fee of $7.00 and $0.50 per ticket for the rides. Carnival Q charges an entree fee of $12.00 and $0.25 per ticket for the rides. How many tickets must be purchased in order for the total cost at Carnival T and Carnival Q to be the same? 25
Let, number of tickets required so that total cost is same is x.
Cost at carnival T :
T = 0.50x + 7.00 ....1)
Cost at carnival Q :
Q = 0.25x + 12.00 ....2)
For same cost , T = Q :
0.50x + 7 = 0.25x + 12
0.25x = 5
x = 20
Therefore, for same cost at both the carnival 20 tickets should be purchased.
Hence, this is the required solution.

The digit at the tens place of a two digit number is three times the digit at ones place . If the sum of this number and the number formed by reversing it's digits is 88 . Find the number .
Digit at the ten's place is three times the digit at ones place.
The sum of the number and the number formed by reversing the digits = 88
Find:the number
Solution:Let the digit at ten's place be x and digit at one's place be y.
The number = 10x + y or xy
Digit at the ten's place is three times the digit at ones place.
→ x = 3y -- equation (1)
Also,
The sum of the number and the number formed by reversing the digits = 88
Number formed by reversing the digits = 10y + x
Hence,
→ 10x + y + 10y + x = 88
→ 11x + 11y = 88
→ 11(x + y) = 88
→ x + y = 88/11
Substitute the value of x from equation (1).
→ 3y + y = 8
→ 4y = 8
→ y = 8/4
→ y = 2
Putting the value of y in equation (1) we get,
→ x = 3 * 2
→ x = 6
The number = xy = 62.
Therefore, the required two digit number is 62.
I hope it will help you.

Olivia wants to make math party bags. She has 24 pencils and 4 erasers. If she makes the maximum number of possible bags, how many pencils will be in each one?
Answer:
6 pencilsStep-by-step explanation:
Number of pencil = 24 pencils
Number of erasers = 4 erasers
If she makes the maximum number of possible bags, the number of pencil that will be in each can be gotten by taken the GCF of both vales (24 and 4)
For 24:
24 = 4 * 6
For 4:
4 = 4 * 1
Since 4 is common to both factors, this means that the number of possible bags you can make is 4 and the number of pencil in each will be 6pencils
