Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1....Complete the multiplication and the equation becomes ....The two fractions now have like denominators so you can subtract the numerators. This fraction cannot be reduced.....and that's how i got the answer

Technology affected American lifestyles in two main ways. First, it gave Americans more leisure time. By the 1920s, there were many more labor saving devices, particularly ones that reduced the difficulty of housework. These gave Americans more time to do things other than simply working.
Tech has influenced american lives in two ways. For starters, it offered more leisure time for americans. Even by the 1920s, there were far more technological solutions for employment, especially those that made housekeeping easier.
This provided Americans with extra time to do things other than work.The vehicle, plane, washer and dryer, radio, moving assembly, refrigerator, garbage disposal, electric razor, instant picture, nightclub, and radio were among the technologies that helped transform America in the 1920s.Labor-saving gadgets allowed people more free leisure time as the new technologies of the 1920s transformed people's lives.Therefore, the final answer is "Option A".

Solve for x.
Answer:
x = 9
Step-by-step explanation:
Theorem:
The measure of an exterior angle of triangle equals the sum of the measures of its two remote interior angles.
The angle measuring 12x + 14 is an exterior angle of the triangle.
The angles measuring 76 deg and 1 + 5x are its remote interior angles.
12x + 14 = 1 + 5x + 76
12x + 14 = 5x + 77
7x = 63
x = 9
Ms. Carter runs 7.3 miles a day
for 14 days. How many miles
did she run in all?
Answer: 102.2
Step-by-step explanation:
Pretty sure
I dunno how to solve this
Answer:
9
Step-by-step explanation:
First off you need to find the interval that four falls in.
Four is not less than three so you can rule out the first one, four is not greater than 10 so you can rule out the last one. But four is greater than three and less than ten, so it falls in the second interval.
So, now you can substitute four in for x for the second equation
4^2-7
16-7
=9

Step-by-step explanation:
Answer: 0.5
a) boys: 14

what is the answer to this?
Answer:
y = 3, TU = 6
Step-by-step explanation:
SU is an angle bisector and divides the opposite side into segments that are proportional to the other 2 sides, that is
[tex]\frac{SV}{ST}[/tex] = [tex]\frac{VU}{TU}[/tex] , substitute values
[tex]\frac{24}{4y-2}[/tex] = [tex]\frac{14.4}{2y}[/tex] ( cross- multiply )
14.4(4y - 2) = 48y
57.6y - 28.8 = 48y ( subtract 48y from both sides )
9.6y - 28.8 = 0 ( add 28.8 to both sides )
9.6y = 28.8 ( divide both sides by 9.6 )
y = 3
Then
TU = 2y = 2 × 3 = 6
If a machine that prints designs on T-shirts prints 500 shirts in 3 hours, how many hours will it take to print designs on 1,800 shirts?
500 shirts / 3 hours = 166 2/3 shirts per hour.
Divide total shirts by shirts per hour:
1800 / 166 2/3 = 10.8 hours.
Question 695271
{{{500/3=1800/x}}}
Cross multiply:
{{{(3*1800)/500}}}
=10.8 hours

[tex] - 2 \sqrt{7} [/tex]
Answer:
A. -2[tex]\sqrt{7}[/tex]
Step-by-step explanation:
3 - 5 = -2
The [tex]\sqrt{7}[/tex] is just like an x variable at this point because they are both the same. If it was [tex]\sqrt{7}[/tex] and [tex]\sqrt{14}[/tex] for example, then you wouldn't be able to subtract them so easily. Kinda like how you can't subtract 3x-5y because they're two different variables.

Solve the equation 2x2 + 14x – 6 = x2 + 7x to the nearest tenth.
(x2+4x+8)+ (2x2 +5x+9)
Answer:
[tex]\left(x^2+4x+8\right)+\left(2x^2+5x+9\right)=3x^2+9x+17[/tex]
Step-by-step explanation:
Given the expression
[tex]\left(x^2+4x+8\right)+\:\left(2x^2\:+5x+9\right)[/tex]
solving the expression
[tex]\left(x^2+4x+8\right)+\:\left(2x^2\:+5x+9\right)[/tex]
remove the parentheses
[tex]\left(x^2+4x+8\right)+\:\left(2x^2\:+5x+9\right)=x^2+4x+8+2x^2+5x+9[/tex]
Group like terms
[tex]=x^2+2x^2+4x+5x+8+9[/tex]
Add similar elements: x² + 2x² = 3x²
[tex]=3x^2+4x+5x+8+9[/tex]
Add similar elements: 4x + 5x = 9x
[tex]=3x^2+9x+8+9[/tex]
[tex]=3x^2+9x+17[/tex]
Therefore, we conclude that:
[tex]\left(x^2+4x+8\right)+\left(2x^2+5x+9\right)=3x^2+9x+17[/tex]

B)-2
C)1
D)4
Answer:
[tex]y = \frac{-1}{2}[/tex]
Step-by-step explanation:
Explanation:-
Given the function
[tex]y = \frac{1}{2x +6}[/tex]
Put x =-4 in given function
[tex]y = \frac{1}{2(-4) +6} = \frac{1}{-8+6} = \frac{-1}{2}[/tex]

You have a bag of 15 marbles. 8 are red. 5 are blue. 2 are green. What is the probability of randomly pulling out a blue marble on the first try?
a. Because it is random, you can't calculate the probability
b.33%
c.3.3%
d.0.3 %
Answer:
33%
Step-by-step explanation:
to find the percentage of the probability you have to divide the number of diff ways of pulling out a blue marble to all the diff ways of pulling a random marble. the blue ones are 5 in total and that many are the diff ways of pulling out one, while all the diff ways of pulling a rando are equal to the total number of marbles, which is 15. so you just have to divide 5/15=1/3, whish is 33.(3)%
