if you make $391 for 17 hours how much would you make in 13 hours
Answer:
We would make $299 in 13 hours.
Step-by-step explanation:
Hi there!
We're given:
⇒ We make $391 in 17 hours
To find how much we make in 13 hours, we must first find how much we make in 1 hour. Divide $391 by 17 hours:
391 ÷ 17 = 23
Therefore, we make $23 in 1 hour.
Multiply $23 by 13 hours to find how much we would make in 13 hours:
23 × 13 = 299
Therefore, we would make $299 in 13 hours.
I hope this helps!

-2, 4, 10, 16 what’s the nth term for this sequence
Answer:
22
every term is being added by 6
-2 + 6 = 4
4 + 6 = 10
10 + 6 = 16
16 + 6 = 22
Step-by-step explanation:
Answer:
-8 +6n
Step-by-step explanation:
Explicit rule:
[tex]a_{1} = -2[/tex]
d = Common difference = term 2 - term 1
= 4 -(-2) = 4 + 2 = 6
[tex]a_{n}=a_{1}+d*(n-1)\\\\a_{n}=-2 + 6*(n-1)\\\\a_{n}= -2 +6n - 6\\\\\\[/tex]
= -2 - 6 + 6n
= -8 + 6n
Solve the equation x^2-12x=0
Answer:

6. Andrew is planning on taking a vacation to Santorini, Greece which will cost $5,000. He makes $2900 ser
month. His fixed expenses are $1200 each month. He spends $200 on food and 5% of his monthly salary on
entertainment. How many months will it take to save enough for Andrew to go to Santorini, Greece
Answer: 3 months
Step-by-step explanation:
Answer:
3 1/2 months (Someone please check my math)
Step-by-step explanation:
We can set up this problem by making an equation.
(2900-1200-200-5%)(x)=5000
(1500-5%)(x)=5000
(1425)(x)=5000
5000 divided by 1425 equals 3.50...
My answer would be 3 1/2 months but I could be wrong.

Answer:
Step-by-step explanation:
Domain means what is the lowest value of x on the graph and what is the highest. Our graph begins at an x value of -5 (but -5 is not included because the dot is not filled in) and goes all the way up to 2 (but 2 is not included either since the dot is not filled in. Therefore, the domain is
D = {x | x ∈ R, -5 < x < 2}
which means that the domain is in the set of real numbers that begin at -5 and end at 2, neither included.
Choice F is the one you want.

How much does the refrigerator cost?
Answer: $535
Step-by-step explanation
He will be able to buy the refrigerator with the amount he deposited ($500) plus the interest generated from it ($35)(which we get by doing the following):
So the formula for interest is
Interest = (principal ×interest rate × time for which the money was deposited) / 100
Interest = ?
Principal = $500
Interest rate = 7%
Time = 1 year
Now
Interest = (500 × 7 × 1) / 100
Interest = 3500/ 100
Interest = $35
So the refrigerater's cost = 500 + 35
Cost = $ 535
Write the equation of a line that is perpendicular to y=-2/7x + 9 and that passes through the point (-4,6) [FP]
Answer:
$y=(7/2)x+20$
Step-by-step explanation:
SInce the gradient of the first line is $-2/7$ then the gradien of the perpendicular line is $7/2$.
Therefore by the point slope formula the line that we are looking for is
$y-6=(7/2)(x+4)$
$y=(7/2)x + 20$

If 7m - 3 = 53. What is the value of 11m + 2?
Answer:
90.
Step-by-step explanation:
7m - 3 = 53
m would be 8 because 56 - 3 = 53.
11m + 2 equals 90 because 11 times 8 (8 is m) is 88, which added by two is 90.
| 7x-2 | +3 = -1 solve for x
Answer:
x = -2/7 or
x = 6/7
Step-by-step explanation:
|7x-2| + 3 = -1 subtract 3 from both sides
|7x-2| = -4 now there are two probabilities
7x-2 = -4 or
7x-2 = 4 if first probability the value of x would be:
7x-2 = -4 add 2 to both sides
7x = -2 divide both sides by 7
x = -2/7 for the second probability the value of x would be:
7x-2 = 4 add 2 to both sides
7x = 6 divide both sides by 7
x = 6/7
Find the value of 9w + 1 given that -5w -5 = 5
Answer:
-17
Step-by-step explanation:
First, let's see what the value of w is, by solving -5w - 5 = 5.
-5w - 5 = 5 Add 5 on both sides.
-5w = 10 Divide -5 on both sides.
w = -2
Now, we know that w is equal to -2, let's plug it in to find the value.
9(-2) + 1 Distribute.
-18 + 1 Add.
