Answer:the example equation becomes "x + 10 - 15x = 20," which is then "-14 x + 10 = 20." Subtract 10 from each side, divide by 14 and you have end up with x = -10/14, which simplifies to x = -5/7. Plug in the x value in to the first equation to find out the y value.
Step-by-step explanation:
Answer:
x=9
y=14
Step-by-step explanation:
Your picture shows that the two angles are congruent so:
2[(2x+27)]=90
4x+54=90
4x=36
x=9
Your picture shows the two horizontal lines as congruent also so:
4y-19=y+23
4y-19+19=y-y+23+19
3y=42
y=14

When Three friends divide four boxes of baseball trading cards ?evenly, they each get 48 cards. How many cards are in each box?
Answers
Answer:
36 cards in each box
Step-by-step explanation:
Let the number of cards in each box be x.
4 * x / 3 = 48 (4 packs of cards, three friends)
x / 3 = 21
x = 36.
Answer:
36 cards in each box
Step-by-step explanation:
Because each friend gets the same amount of cards, there needs to be 48*3 or 144 trading cards in total. There are 4 boxes so in each box there would be 144/4 or 36 cards in total.

9x + 5 = 4(x + 2) + 5x
solve for X
Answers
Answer:
no solution
Step-by-step explanation:
9x + 5 = 4(x+2) + 5x
9x + 5 = 4x + 8 + 5x
9x + 5 = 9x + 8
9x + 5 can never be equal to 9x + 8, so the answer is no solution
Answer:
x=3
Step-by-step explanation:
9x + 5 =4(x+2) + 5x
9x + 5= 4x + 8+ 5x ( do the parenthesis first- mulitiply 4 and x and get 4x and 4 times 2 = 8)
9x + 5 = 9x + 8 ( add the x's together 4x +5x = 9x )
9x = 9x + 3 ( subtract 5 both sides and you get 3 )
=3 ( subtract 9x from both sides

Justin jogged for four days in a row. He jogged 2 miles the first day. On the second day, he jogged 75% of the distance he jogged the first day. On the third day, he jogged 1.5 miles more than the distance he jogged the first day. If Justin jogged a total distance of 9.25 miles, how many miles did he jog on the fourth day?
Answers
Answer:
2.75 miles jogged on the fourth day
Step-by-step explanation:
Justin jogged 2 miles on the first day.
On the second day he jogged 75% of 2 miles. To find 75% of 2 miles we need to divide by 100 and multiply by 75.
2 / 100 = 0.02 x 75 = 1.5 miles jogged on the second day. (3.5 miles jogged in total so far)
On the third day he jogged 1.5 miles more than the last day:
1.5 + 1.5 = 3 (6.5 miles jogged so far)
9.25 total miles were jogged, meaning that we will need to subtract 6.5 from 9.25 to get the answer:
9.25 - 6.5 = 2.75 miles jogged on the fourth day

The total of the shirts and pants is $65.
She bought 9 shirts and 4 pants, which would be 13 shirts and pants.
We then divide the total cost of the shirts and pants, $65 by the total shirts and pants, 13.
65 / 13 = 5
So, each shirt or pants costs $5.

The linear relationship between the different possible combinations of X and Y is Y= -X + 18.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
We know that after sleeping for 6 hours, there are 18 hours left in a day. These 18 hours can be split between leisure time and study time.
Now,
Let's let X be the number of hours of leisure time, and Y be the number of hours of study time.
Since we know that there are a total of 18 hours,
we can set up the following equation.
X + Y = 18
This equation represents all the possible combinations of X and Y that add up to 18 hours.
Now,
To represent a linear relationship between X and Y.
Y = -X + 18
This equation represents a linear relationship between X and Y.
Where X is the independent variable and Y is the dependent variable.
This is in the form of a slope-intercept form.
y = mx + c
Where m = -1 and c = 18
So,
The slope = -1 and the y-intercept is 18.
Thus,
Y= -X + 18 represents all the different possible combinations of leisure time and study time that adds up to 18 hours.

0.30 of a book / hour or 3/10 of a book per hour.
Step-by-step explanation:
Usually I tell people to put the numbers into decimals. Unfortunately for this question, it won't work. So we have any choice but to do it with fractions.
r = amount / time
amount = 1/4
time = 5/6
r = [tex]\frac{\frac{1}{4} }{\frac{5}{6} }[/tex]
Invert the denominator and multiply
r = [tex]\frac{1}{4} * \frac{6}{5}[/tex]
r = 6 * 1 / (5*4) = 6/20 = 3/10
The answer is 3/10 of a book per hour
5/6 of an hour is almost an hour.
1/4 of a book is 0.25 of a book.
3/10 of a book is 0.30 of a book. So it looks like it is just about right.

Spins a fair spinner numbered 1 - 5 and flips a fair coin. What is the probability of obtaining a factor of 15 and a tail?
Answers
Answer:
3/10
Step-by-step explanation:
Probability is the ratio of the number of possible outcome to the number of total outcome.
Given that the fair spinner is numbered 1 - 5, the factors of 15 there are 1, 3 and 5 hence the probability of obtaining a factor of 15
= 3/5
The probability of obtaining a tail from the flip of a coin
= 1/2
Hence the probability of obtaining a factor of 15 and a tail
= 3/5 * 1/2
= 3/10
