x/7 +13/14 = 17/14
double the first one so all the denominators are the same
2x/14+13/14=17/14
then subtract the second fraction from the thrid
2x/14=4/14
then we can divide by two so we are back to 7 as the demoninator
x/7=2/7

Answer:
ΔABD ≅ ΔCBD by SAS Congruence Postulate (Option C)
Step-by-step explanation:
In ΔABD & ΔCBD ,
1) AD = CD = 15 units
2) ∠ADB = ∠CDB (∵ BD is angle bisector)
3) BD = BD (common side)
∴ ΔABD ≅ ΔCBD by SAS congruence postulate.
Answer:
Triangles ABD and CBD are congruent by SAS.
Step-by-step explanation:
Sides AD and CD are congruent since they both measure 15.
Angles ADB and CDB are congruent because of the angle bisector.
Side DB is congruent to itself.
By SAS, triangles ABD and CBD are congruent.
Answer: Triangles ABD and CBD are congruent by SAS.
Triangle LMN with vertices L(0, 3), M(3, 4), and N(1, 2): a) 180° rotation about the origin b) dilation with scale factor of 2 using the origin as the center
Answer:
[tex]L" = (-6,0)[/tex] [tex]M" = (-8,-6)[/tex] [tex]N" = (-4,-2)[/tex]
Step-by-step explanation:
Given
[tex]L = (0,3)[/tex]
[tex]M = (3,4)[/tex]
[tex]N = (1,2)[/tex]
Required
Determine the new coordinates of L, M and N
Applying (a): 180 degrees rotation about the origin
When [tex](x,y)[/tex] is rotated about 180 degrees, the new point becomes [tex](-y,-x)[/tex]
So:
[tex]L = (0,3)[/tex] ==> [tex]L' = (-3,0)[/tex]
[tex]M = (3,4)[/tex] ==> [tex]M' = (-4,-3)[/tex]
[tex]N = (1,2)[/tex] ==> [tex]N' = (-2,-1)[/tex]
Applying (b): Dilation of scale factor, 2
The formula to apply here is;
[tex]New = Old * Scale\ Factor[/tex]
So:
[tex]L' = (-3,0)[/tex] becomes:
[tex]L" = L' * 2[/tex]
[tex]L" = (-3,0) * 2[/tex]
[tex]L" = (-6,0)[/tex]
[tex]M' = (-4,-3)[/tex] becomes:
[tex]M" = M' * 2[/tex]
[tex]M" = (-4,-3) * 2[/tex]
[tex]M" = (-8,-6)[/tex]
[tex]N' = (-2,-1)[/tex]
[tex]N" = N' * 2[/tex]
[tex]N" = (-2,-1) * 2[/tex]
[tex]N" = (-4,-2)[/tex]
Hence;
The new coordinates are:
[tex]L" = (-6,0)[/tex]
[tex]M" = (-8,-6)[/tex]
[tex]N" = (-4,-2)[/tex]
Jackson kitten weighed 2 pounds 3 ounces a month later the kitten weighed 56 ounces. How munch weight did the kitten gain in that month. How many ounces did the kitten gain
Answer: 21 ounces
Step-by-step explanation:
From the question, we are told that Jackson kitten weighed 2 pounds 3 ounces a month. We should note that 16 ounces = 1 pound.
Therefore we'll convert 2 pounds, 3 ounces to ounces. This will be:
= (2 × 16 ounces) + 3 ounces
= 32 ounces + 3 ounces
= 35 ounces
We are further told that later the kitten weighed 56 ounces.
The amount of weight gained by the kitten in that month will be:
= 56 ounces - 35 ounces
= 21 ounces
The equation f equals 9/5 C + 32 relates temperature measured in degrees celsius C to degrees Fahrenheit f Determine whether there is a proportional relationship between C and F explain your reason
Given:
[tex]F=\dfrac{9}{5}C+32[/tex]
where, F is degree Fahrenheit and C is degree Celsius.
To find:
Whether there is a proportional relationship between C and F.
Solution:
We know that, proportional relations is defined as
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
where, k is constant of proportionality.
So, the line of proportional relationship passes through (0,0) and the equation must be true for (0,0).
If there is a proportional relationship between C and F, then the equation must be true for (0,0).
Substituting F=0 and C=0 in the given equation, we get
[tex]0=\dfrac{9}{5}(0)+32[/tex]
[tex]0=0+32[/tex]
[tex]0=32[/tex]
This statement is false because [tex]0\neq 32[/tex].
It means the line of given equation does not passes through (0,0). So, it s not a proportional relationship.
Hence, there is not a proportional relationship between C and F.

PLEASE PLEASE HELP ME ! Jerry wants to buy his grandpa's old car for $500.00. He works 10 hours a week
at $7.50 an hour. How many weeks will he need to work before he earns enough
money to buy the car? Write and equation
Answer:
Step-by-step explanation:
Needs $500 Makes 7.50 and works 10 hours week.
7.50*10= $75.00 a week
500/75= 6.6 weeks or 6 weeks and 2/3 of a week. I'd round to 7 weeks.
75(x)=500 X= weeks needed.
75x=500 if you divide 500 by 75
x=20/3 or 6.6

Answer:
It says to Graph y = 1/2x - 4
So equation y = 1/2x - 4
this corresponds to slope intercept form which is y = mx + b
M = slope = rise / run
B = y - intercept
First, start at the origin, (0,0)
Then go down 4, you should now be on the coordinate (0,4)
Now we need to use the slope.
The slope is 1 / 2, this means rise 1, run 2 (in this case 2 to the right because it is positive)
So, start at (0 , 4) and go up 1 unit then 2 to the right, then place a dot, keep repeating until you meet the end of the paper.
Then do the opposite so that you can graph the other side.
Down 1 and 2 to the left.
Answer:
Graph Points (0.-4) and (8,0) and connect the dots into a line
Step-by-step explanation:
To graph y=1/2x-4 you will need to find the y and x-intercept. To find an intercept you have to substitute the x and y variables with 0 one at a time. I first substitute the x variable with an 0 and got the equation y=-4 so my y-intercept is (0.-4). Then I substituted the y variable with 0 and got 0=1/2x-4, I added 4 on each side to get rid of it and got 4=1/2x. I then multiplied both sides by 2 to get the x by itself and got 8=x so my x-intercept is (8,0). Whenever your graphing slope-intercept form equations just find the y and x-intercepts, graph them, connect the dots.

Sally bought 124 sheets of stickers. Each sheet had 14 stickers. She gave away 204 stickers to her family and friends on Christmas. How many stickers does Sally have remaining?
Answer:
Sally has 1,532 stickers remaining.
Step-by-step explanation:
First, you have to determine the total amount of stickers Sally bought by multiplying the number of sheets she bought for the number of stickers in each sheet:
124*14=1,736
Now, you have to subtract the number of stickers Sally gave away to her family and friends from the total amount of stickers she bought:
1,736-204=1,532
According to this, the answer is that Sally has 1,532 stickers remaining.

Apples cost $1.47 per pound. Danielle buys an apple that weighs 0.62 pound. To the nearest cent, how much does Danielle’s apple cost?
Answer:
91 cents
Step-by-step explanation: Just a hunch
The amount that Danielle’s apple cost is $0.91.
Using this formula
Cost=Sales price per pound× Weight per pound
Where:
Sales price per pound=$1.47
Weight in pound=0.62 pound
Let plug in the formula
Cost=$1.47×0.62
Cost=$0.91
Inconclusion the amount that Danielle’s apple cost is $0.91.

Answer:
x=3 y=-1
Step-by-step explanation:
2x+3y=3;y=8−3x
Rewrite
y=−3x+8 2x+3y=3
Step: Solvey=−3x+8 for y:
y=−3x+8
Step: Substitute−3x+8foryin2x+3y=3:
2x+3y=3
2x+3(−3x+8)=3
−7x+24=3(Simplify both sides of the equation)
−7x+24+−24=3+−24(Add -24 to both sides)
−7x=−21
−7 - 7
x=3 (Divide both sides by -7)
x=3
Step: Substitute3forxiny=−3x+8:
