Answer:
x=10
Step-by-step explanation:
x^2 - 10 - (9x) = 0
x^2 - 9x - 10 = 0
(x - 10) + (x + 1) = 0
x= 10
x = -1

Answer:
A
Step-by-step explanation:
Since slope is rise over run:
The slope of KM would be [tex]\frac{KL}{LM}[/tex] and the slope of PS would be [tex]\frac{PR}{RS}[/tex]
So [tex]\frac{KL}{LM}[/tex] = [tex]\frac{PR}{RS}[/tex]

Use Quadratic equation to solve
a2 -4a - 4 = 0
Answer:
a = 2 ± 2[tex]\sqrt{2}[/tex]
Step-by-step explanation:
a = 1
b = -4
c = -4
x = (-b ± [tex]\sqrt{b^2 - 4ac}[/tex]) / 2a
x = (-(-4) ± [tex]\sqrt{(-4)^2-4(1)(-4)}[/tex]) / 2(1)
x = (4 ± [tex]\sqrt{16 +16}[/tex]) / 2
x = (4 ± 4[tex]\sqrt{2}[/tex]) / 2
x = 2 ± 2[tex]\sqrt{2}[/tex]
Your variable being solved is a so a = 2 ± 2[tex]\sqrt{2}[/tex]
If the slope is 3/4 what does the 4 tell us to do?
It means we need to move 4 spaces to the
type your answer
in the positive direction
Hey there!
3/4 means Rise/Run. Guess why the rise is called the rise and the run is called the run.
The 4 tells us to move 4 units in this direction:

That was meant to represent an arrow.
Hope it helps!
[tex]ANSWERED:\\GraceRosalia[/tex]
Answer:
The 3 tells you to move 3 spaces up and the 4 tells you to move 4 spaces to the right.
Step-by-step explanation:
All slope can be visualized as "rise over run" meaning the top number is how far you go up or down depending on whether it is positive or negative and run can be visualized as how far to the right you move or if it is negativ, how far to the left.
On a ship, the ratio of crew members to passengers is 1:15.There are 540 passengers. How many crew members are there? ( Explain it easier)
Answer:
36 Crew Members
Step-by-step explanation:
So for every 1 crew member, there are 15 passengers.
So divide 540 by 15: 540/15=36
So by dividing that you get the number of crew members: 36
120% of what number is 102 and how do you write it in an equation? (Include a variable)
Answer:
y = 85
Step-by-step explanation:
120% times y = 102
The variable is y.
what is the measure of
The two given angles add together to make a linear pair, which is 180 degrees.
(2x + 8) + (2x) = 180
4x + 8 = 180
4x = 172
x = 43
Angle ABC = 2(43) + 8 = 86 + 8 = 92 degrees

Hugh bought some magazines that cost $3.95 each and some books that cost $8.95 each. He spent a total of $47.65. Let m represent the number of magazines and b represent the number of books. Which equation models the situation?
Answer:
3.95m + 8.95b = 47.65
Step-by-step explanation:
Since Hugh paid $3.95 for every magazine, m would be multiplied by 3.95
Since he also paid $8.95 for every book, b would be multiplied by 8.95
All of this will eventually add up to a sum of 47.65

If you take out a loan for $561.60 over eight years at an interest rate of 9.3%, what is the total amount you will have to repay?
The simple interest of a given sum is directly proportional to the rate of interest. The total amount for repayment is $979.43.
What is Simple interest ?The simple interest is a method of calculating the interest over a sum without considering the compounding.
The simple interest over a period of time varies as arithmetic progression.
Given that,
The amount of loan P = $561.60
Time for the interest T = 8 years.
Rate of interest R = 9.3%.
The total amount A can be given by summing the amount of loan to the interest over it as,
A = P + S.I
And the simple interest is given as,
S.I = (P × R × T) / 100
= (561.60 × 9.3 × 8) / 100
= 417.83.
The amount is given as,
A = 561.60 + 417.83
= 979.43.
Hence, the total amount to be repaid is $979.43.

20 mph
O
30 mph
d
40 mph
50 mph
Answer:
30 miles per hour
Step-by-step explanation:
You divide the distance by time to receive the average speed.
270 / 9 = 30
Answer:
The train travels 30 miles in 1 hour
Step-by-step explanation:
First, you take the miles and divided it by the hours. That will give you the average speed/MPH (miles per hour)
