then multiply by 7)
Answer:
280
Step-by-step explanation:
160 divided by 4 is 40 then times that by 7 and u get 280
Answer:
280 miles
Step-by-step explanation:
First you have to find how many miles a car travels in 1 hour. (160 ÷ 4 = 40).
Then, once you find that, you multiply 40 by 7. (280)

f(x)/g(x)
(x2-1)/(x-1)
x cannot equal 1 because this would render the denominator, also known as the divisor, as zero.
x can be greater than 1.
If you would like, we can factor the numerator...
x2-1
(x+1)(x-1)
FIRST...(x)(x)=x2
OUTER...(x)(-1)=-1x=-x
INNER...(1)(x)=1x=x
LAST...(1)(-1)=-1
x2-x+x-1
x2-1
So...
f(x)/g(x)=[(x+1)(x-1)]/(x-1)
(x-1) is in the numerator and denominator. It cancels...
f(x)/g(x)=(x+1)
What is the slope of a line parallel to the following line: 5x + 8y = 50
Answer:
-5/8
Step-by-step explanation:
Convert standard form to slope-intercept form to find the slope.
5x + 8y = 50
8y = -5x + 50
y = -5/8x + 50/8
Slope: -5/8
Answer:
-5/8x
Step-by-step explanation:
First you need to find the slope of the given line.
Do this by converting it to slope intercept form (y=mx+b)
Divide the whole equation by 8 to isolate the y variable.
After dividing by 8 you should now have 5/8x + y = 6.25
Now you need to subtract y and 6.25 to isolate y
5/8x - 6.25 = -y
Now you have to divide the whole equation by negative 1 to make y positive. You end up with: y = -5/8 + 6.25
We know that the slopes of parallel lines are equal. Therefore the answer is -5/8x
-8+ 12x + 7x+12=

2) Gas mileage is the number of miles you can drive on a a gallon of gasoline.
A test of a new car results in 510 miles on 10 gallons of gas. How far could
you drive on 55 gallons of gas? What is the car's gas mileage?
Help me please!!
This is my last question ..
Answer:
You could drive 2805 miles on 55 gallons of gas
The car's gas mileage is 51 miles per gallon
Step-by-step explanation:
First, find the gas mileage by dividing the given number of miles by the number of gallons:
510/10
= 51
The car's gas mileage is 51 miles.
Find how far you can drive on 55 gallons of gas by multiplying 51 by 55
51(55)
= 2805
So, you can drive 2805 miles.
find the value of x
Answer:

Answer:
6. $44,506.92
7. $20,197.88
8. $8,132.84
9. $20,137.53
Step-by-step explanation:
The formula for future value is ...
FV = P(1 +r/n)^(nt)
for principal P at annual interest rate r compounded n times per year for t years.
This formula is built in to most spreadsheet programs, which can be usefully used to calculate its value for different values of the variables. The spreadsheet function needs the interest rate per period (r/n) and the number of periods (nt).
Continuous compounding can be reasonably approximated by compounding 100 million times per year. Or the continuous compounding formula can be used:
FV = Pe^(rt)
The attached spreadsheet shows the values for these problems, and it shows the formula used to obtain them.
_____
Additional comment
Spreadsheet functions often work in terms of cash flow. A payment has one sign, and a value received has the opposite sign. Here, we have shown -FV( ) in the spreadsheet, because the given arguments would otherwise show the FV as negative. (More properly, the last function input would be the opposite of the principal value, as it is a payment being made.)
-2x+y=-8 and 4x-6y=-24 I need help :(
Answer: 2x+y=-8 = x=-1/2y-4
4x-6y=-24 = x =3/2y-6
Step-by-step explanation:
2x+y=-8 -- Step 1: Add -y to both sides.
2x+y+−y=−8+−y
2x=−y−8
Step 2: Divide both sides by 2.
2x/2=-y-8/2
4x-6y=-24 -- Step 1: Add 6y to both sides.
4x−6y+6y=−24+6y
4x=6y−24
Step 2: Divide both sides by 4.
4x/4=6y-24/4

-7n + 10 = -24
step by step please this is algebra and it’s hard to me Lol
Answer:
n = -34/7
Step-by-step explanation:
So what you want to do is find n, which means you have to get n by itself. So first you want to subtract 10 from both sides.
-7n + 10 = -24
- 10 - 10
-7n = -34
We got a negitive 34 because a negitive - negitive = a negitive
Now, you want to divide -7 from both sides.
-7n = -34
--- ----
-7 -7
n = -34/7
This cannot be simplified so you will keep it as a fraction.

Answer:
The lengths of DF and HI
Step-by-step explanation:
SSS
This means Side Side Side
So to prove this triangle is similar we have to use only true information about the sides.
We can already cross off the second and last answer choices because they are talking about angles.
The first answer choice is about the sides but first we have to determine if its true or not.
Side DF is on the left opposite of angle G
HI is also on the left, opposite of angle I
We can assume those sides are the same but to really know we can check if the other sides match up
We know this constriction has a scale factor of: 1.66666667
If you divide 3.5 by our scale factor you get 2.1
If you divide 5 by our scale factor you get 3
This proves that DG and HJ and FG and IJ would be the matching constricted side
This means that DF and HI would be matching as well making the first answer choice correct.
I hope this helps, don't be afraid to reach out with any further questions! Have a nice day!
On a number line, the coordinates of j, k, l, m, n are −10.5, −4, −1, 1.5, 4 respectively. Find the lengths of the two segments. Are they congruent? Jl¯¯¯¯¯¯ and kn ¯¯¯¯¯¯¯
Answer and Step-by-step explanation: A Line Segment is a part of a line with two endpoints and fixed length.
The length of segment JL is
JL = [tex]-1-(-10.5)[/tex]
JL = 9.5 units
And of KN:
KN = [tex]4-(-4)[/tex]
KN = 8 units
The term congruent refers to an object, form or figure that have the same shape and size.
Both segments have the same shape (a line), however not the same size. So, segments JL and KN are not congruent.
(a) Reflect the point (5 3) across the x-axis:
(b) Reflect the point(5 3) across the y-axis:
Answer:
(5, -3)
(-5, 3)
Step-by-step explanation:
Reflecting across the x-axis makes the y coordinate change from a positive to a negative and reflecting across the y axis makes the x value negative.
