Please help with geometry
Answer:
x = 8
Step-by-step explanation
Complimentary angles have a sum of 90*. Thus when adding the two equations together, we must get 90*.
7x + 17 + 3x - 7 = 90 Combine like terms
10x + 10 = 90 Subtract 10 on both sides
10x = 80 Divide both sides by 10
x = 8
Answer:
x = 8

9514 1404 393
Answer:
52 minutes
Step-by-step explanation:
Streaming Haunted Cave videos used the battery at the rate ...
(76% -16%)/(3·30 minutes) = 60%/(90 minutes) = (2/3)% per minute
Playing Top Pop used the battery at the rate ...
(63% -59%)/(24 minutes) = (4/24)% per minute = (1/6)% per minute
The remaining charge (in percent) after x minutes for Jorge's phone will be ...
J = 55 -2/3x
The remaining charge for Samantha's phone will be ...
S = 29 -1/6x
We can find the value of x that makes these equal:
J = S
55 -2/3x = 29 -1/6x
26 = 1/2x . . . . . . . . . . . . . . . add 2/3x -29 to both sides
52 = x . . . . . . . . . . . multiply by 2
It will be 52 minutes before the two phones have the same battery level.

midpoint (12, -9), endpoint (19, 0) the other endpoint is
Answer:
(5, -18)
Brainliest, please!
Step-by-step explanation:
(12, -9)(19, 0)
x distance: 7, y distance: 9
To get the other endpoint, we must apply the opposite.
x distance: -7, y distance: -9
(12, -9)
12 - 7 = 5, -9 - 9 = -18
(5, -18)

6=_-(-8) find the missing value
Answer:
-2
Step-by-step explanation:
when there are two negative signs directly next to each other, it becomes a positive. Set the equation. Let the unknown number be signified by the variable, x:
6 = x - (-8)
6 = x + 8
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 8 from both sides of the equation:
6 (-8) = x + 8 (-8)
6 - 8 = x
x = 6 - 8
x = -2
-2 is your missing value.
~
Hey there!
6 = ____ - (-8)
• We’re going to substitute the blank value as “x” because we don’t know the variable is just yet.. it is unknown
x - (-8) = 6
x + 8 = 6
SUBTRACT 8 to BOTH SIDES
x + 8 - 8 = 6 - 8
CANCEL out: 8 - 8 because that gives you 0
KEEP: 6 - 8 because that helps solve for the x-value
x = 6 - 8
6 - 8 = x
x = -2
Answer: -2

I am a three-digit number
My second an last digit are the same
The product of the digit of the numbe one less than me is not zero
The number one less than me is divisible by 45
Please help me solve this riddle. Thank you.
Answer:
766?
Step-by-step explanation:
Answer and Step-by-step explanation:
Three Digit Number.
***
Second digit = Last digit
*xx
I multiplied 45 from numbers 1-23, with 22 being the maximum # to multiply to get a 3 digit number that is divisible by 45, and 3 being the minimum # to multiply to get a 3 digit number that is divisible by 45.
Now to check which number it is.
When you multiply 45 by 17, you get 765. This number is supposed to be 1 less than the riddle's number. It also has to have the last 2 digits be the same.
So, lets add one to 765 to see if we solved the riddle.
765 + 1 = 766
766 is the answer!

The square root of 424 is between what two integers
Answer:
20 and 21
Step-by-step explanation:
424 = 400 + 20 + 4. √400 = 20, as √4 = 2
21² = (20 + 1)² = 400 + 40 + 1 = 441 > 424.

Answer:
a = 3
Step-by-step explanation:
We can start by cross multiplying, which is a method to help solve proportions. We get:
5 * a = 3 * (a + 2)
Now, we can distribute the 3 and solve:
5a = 3a + 6
-3a -3a
2a = 6
/2 /2
a = 3
Answer:
[tex]a = 3[/tex]
Step-by-step explanation:
[tex] \frac{a}{a + 2} = \frac{3}{5} [/tex][tex]a \times 5=(a+2) \times 3[/tex]
[tex]5a=(a+2) \times 3[/tex]
[tex]5a=3a+6[/tex]
[tex]5a−3a=6[/tex]

In a certain country, income tax is assessed by people not having to pay a tax if they make $15,000 per year or less, people having to pay a 12% tax if they make over $15,000 but no more than $30,000, and people having to pay 18% tax if they make more than $30,000 per year. Find the piecewise function that represents this scenario.
Answer:
f(x) = x × 0.12 if 15,000 ≤ x ≤ 30,000
x × 0.18 if x ≥ 30,000
Step-by-step explanation:
I. When 12% is 12/100 = 0.12
and 18% is 18/100 = 0.18

PLS HELP.
Answer:
10+4x+11=x²-10+10 (add 10 both side)

21-21=x^2-4x-21 (substract 21 in both side)
x^2-4x-21=0
x^2+3x-7x-21=0(we can write -4x as (3x)+(-7x)=(-4x)

Answer:
42 students
Step-by-step explanation:
If 4 students had to travel in cars, then 382 - 4 = 378 students traveled in the buses. Since there were 9 buses, 378 / 9 = 42. Therefore, there were 42 students in each bus.
