Solve for x.
3(x - 4) = 2x + 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!

Step-by-step explanation:
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
= 2.1923076

Lena told her mother that the jeans that she bought were on sale for 10 percent off and she had saved $8.25 on them.
Answer:
$82.5
Step-by-step explanation:
Step one:
Given that the percent of which is 10% amount to $8.25
We can estimate the of the Jeans as
Step two
Let the cost be x
10 percent of x= 8.25
10/100*x=8.25
0.1x=8.25
Divide both sides by 0.1 to get the value of x
x=8.25/0.1
x=$82.5
The cost of the jeans is
$82.5
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

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

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
can someone help with this??

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
The product of two positive consecutive integers is 12. Find the
integers. *
Answer:
3, 4
Step-by-step explanation:
The choices for the consecutive integers are: 6, 7, 4, 5 or 3, 4
Test the products of these integers.
6 x 7 = 42
4 x 5 = 20
3 x 4 = 12
The only pair of consecutive integers with 12 as their products is 3 and 4.

5x+4y = -10
x = 3y+17
Answer:
x=3.4
y=-6.75
Step-by-step explanation:
5x+4y=-10 (equation 1 )
-5x+3y=-17 (equation 2)
7y=-27
y=-6.75
substitution (equation 1 ) y=-6.75
5x-27=-10
5x=17
x=3.4

Step-by-step explanation:
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.
