Help me pls also the answer must be a mixed number
Answer:
2 wholes and 5/26
Step-by-step explanation:
convert the mixed number to improper fraction
= -19/6 / -13/9
since there is 2 negatives and (-)/ (-) means your answer is positve
to divide by a fraction multiply by the reciprocal of that fraction.
19/6 x 9/13
reduce 6 and 9 to 3 and 2 becuase both have a GCF of 3.
19/2 x 3/13
multiply 19/2 x 3/13
= 57/26
= 2 wholes and 5/26

Jan spends part of her year as a member of a gym. She then finds a better deal at another gym, so she cancels her membership with the first gym after x months and spends the rest of the year, y months, with the second gym. The membership to the first gym costs $85 per month, while the membership for the second gym costs $50 per month. If she ended up spending a total of $705 over the course of the year, how much time did she spend at each gym?
Answer:
Jan spent 3 months at the first gym and 9 months at the second gym.
Step-by-step explanation:
Given that:
1 year = 12 months
x = months at gym one
y = months at other gym
According to given statement;
x+y=12 Eqn 1
85x+50y=705 Eqn 2
Multiplying Eqn 1 by 50
50(x+y=12)
50x+50y=600 Eqn 3
Subtracting Eqn 3 from Eqn 2
(85x+50y)-(50x+50y)=705-600
85x+50y-50x-50y=105
35x=105
Dividing both sides by 35
[tex]\frac{35x}{35}=\frac{105}{35}\\x=3[/tex]
Putting x=3 in Eqn 1
3+y=12
y=12-3
y=9
Hence,
Jan spent 3 months at the first gym and 9 months at the second gym.

Answer:
C. 58.18 mph
Step-by-step explanation:
Answer:
C. 58.18
Step-by-step explanation:
The average speed means we will do miles per hour (mph). So if there are 640 miles for 11 hours the fraction would look like this:
640/11
We want to find the value for 1 hour so we need the bottom number(denominator) to be 1
Therefore we divide by 11 on the numerator and denominator by 11
58.181818(repeating)/1
This means we travel 58.181818... miles per hour.
If we round to the hundredths place we get 58.18 or option C.
Keep in mind that we can do this in ratio form and still get the same answer:
miles: hours
640:11
58.181818:1

Hello!!!!
A cyclist travels 5 miles each way on a bike path. Travel in one direction is with a 4 mile per hour wind and travel back is against a 4 mile per hour wind. Part A: Write and simplify an equation for the amount of time t in hours it will take the cyclist to make the trip. Part B: What is the cyclist's total travel time, if she travels an average of 6 miles per hour without the wind?
Answer:
a. 10v/(v² - 16) b. 3 hours
Step-by-step explanation:
a. Write and simplify an equation for the amount of time t in hours it will take the cyclist to make the trip.
Let v be the speed of the cyclist without the wind. The speed of the cyclist with the 4 mile per hour wind in the direction of the wind is v' = v + 4. Since the distance travelled is 5 miles, and time, t = distance/speed, the time it takes to make this trip is t' = 5/(v + 4)
Let v be the speed of the cyclist. The speed of the cyclist with the 4 mile per hour wind against the direction of the wind is v" = v - 4. Since the distance travelled is 5 miles, and time, t = distance/speed, the time it takes to make this trip is t" = 5/(v - 4).
So, the total travel time, T = t' + t"
= 5/(v + 4) + 5/(v - 4)
= [5(v - 4) + 5(v + 4)]/[(v + 4)(v - 4)]
= [5v - 20 + 5v + 20)]/(v² - 4²)
= 10v/(v² - 16)
b. What is the cyclist's total travel time, if she travels an average of 6 miles per hour without the wind?
If v = 6 miles per hour, then
T = 10v/(v² - 16)
= 10(6)/(6² - 16)
= 60/(36 - 16)
= 60/20
= 3 hours
Explain whether each is a linear equation
y = 1 - x
Answer:
In a linear equation in x and y, x is called x is the independent variable and y depends on it. We call y the dependent variable. If the variables have other names, yet do have a dependent relationship, the independent variable is plotted along the horizontal axis
:)
Answer:
This should be considered a linear substitution because you can substitute this equation into y in another linear equation to find the answer or the solution to the linear equation

Samantha says the fraction of the group of customers who ordered raspberry topping is 1/2. Explain why samantha is correct.
Answer and explanation:
Yes Samantha is correct. Samantha is correct because a fraction 1/2 of customers who ordered raspberry toppings refers to half of the total number of customers. A fraction 1/2 is 50 percent or 50/100 of the population of customers, therefore meaning that 50% or half of the total number of group of customers ordered raspberry toppings

How would you write 0.5 Repeating as a fraction
Let x = 0.555…
Then 10x = 5.555…
Subtract one from the other to get
10x - x = 5.555… - 0.555…
Notice how the fractional parts on the right cancel. This leaves you with
9x = 5
and so
x = 5/9
Answer:
59
Step-by-step explanation:
Since this fraction repeats the same number it must have a denominator of 9 and a numerator of the repeating digit the repeating digit is 5 so the fraction is 59

x = -6

ΟΑ. Ο
B. 2
C. 3.6
D. 10
E. 18
Answer:
the answer is D. 10
Step-by-step explanation:
you get 3x -4 = 2x +6
you then subtract 2x from 3x and 2x
you get 1x - 4= 6
add 4 to both sides and you get
1x = 10 which is the same as x = 10
Answer:
x = 18
Step-by-step explanation:
3(x-4) = 2x+6
3x-12 = 2x +6
Add 12 to the -12 and the 6, giving you...
3x = 2x + 18
subtract 2 from the 3 and the 2, giving you...
1x = 18
divide the 1 and the 18 by 1, giving you...
x = 18
I hope this helps you out!
