No 4 is easy you get 2/3
My explanation is just make the denominator the same which is 13/6 - 9/7
13 x 7/6x7 - 9x6/7x6
The answer it its 91/42 - 63/42
=28/42
If you simply it it would be 2/3

Answer:

Step-by-step explanation:
why you may ask?
subtracted=being taken away from
13 is *being taken away from* x
so if using numbers, 13 is being taken away from 20
or 13 is being subtracted from 20 would be 7, so x-13 would be your expression

Answer:
area = 120√2 ft² or 169.71 ft²
Step-by-step explanation:
x² = 9² - 3² = 81 - 9 = 72
x = √72 = √(36 x 2) = 6√2 ft or 8.49 ft
area = 1/2(5 + 8)(6√2) = 120√2 ft² or 169.71 ft²
Kay is using cone-shaped party hats as popcorn holders. The party hats have a diameter of 10 inches and a height of 9 inches. How many cubic inches of popcorn will they hold? Use 3.14 for pi. Round your answer to the nearest Cubic inch.
Answers
Answer:
B 236in³
Step-by-step explanation:
you use the equation
V=πr²h/3
π=PI r=Radius h=height
Sense in this problem they give you diameter instead of radius you want to divide it by 2 to get one half.
so the equation used looks like this:
3.14•5²•9/3=235.5
rounded up is 236in³
Hannah buys 3 pairs of shoes for $x each. She uses a $10 off coupon. She
spent a total of $35. Write an equation that can be used to find the cost of each pair of shoes.
Answers
Answer:
$15 per pair
Step-by-step explanation:
We know that the total amount of money she spent on the shoes (without discount) is 3x. Since she used a $10 off coupon, the money she spent is 3x - 10, since $10 off means - 10. And this amount equals $35:
[tex]3x - 10 = 35\\3x = 45\\x = 45/3 \\x = 15[/tex]

Jack and his friends are going hiking next week. There are four trails they can hike: Grayson Pass, Giant’s Ridge, Three Summits, and Elderberry. To make a decision, they use a spinner divided into four colors. They spin it 60 times to check the fairness of their model and record the results in this table.
The relative frequency of the spinner landing on green is
The relative frequency of the spinner landing on blue is
The relative frequency of the spinner landing on yellow is
The relative frequency of the spinner landing on red is
Answers
Answer:
Step-by-step explanation:
The theoretical frequency would be 1/4, and if spun 60 times, 15/60.
The relative frequency is how many times it actually landed on each color.
So green is 6/60
Blue is 24/60
Yellow is 9/60
Red is 21/60
I don't know if they want these in their simplest form (sometimes the test says one way or the other), but here they are, reduced:
Green: 1/10
Blue: 4/10
Yellow: 3/20
Red: 7/20

Answer:
Length = 13 in
Width = 10 in
Step-by-step explanation:
Let L be the length.
Let W be te width.
From the question given above, the Lenght is 3 more that the width i.e
L = 3 + W
Next, we shall determine the width (W). This can be obtained as follow:
Length (L) = 3 + W
Width (W) = W
Area (A) = 130 in²
A = L × W
130 = (3 + W) × W
Clear bracket
130 = 3W + W²
Rearrange
W² + 3W – 130 = 0
Solving by formula method
W = –b ± √(b² – 4ac) / 2a
a = 1
b = 3
c = –130
W = –3 ± √(3² – 4 × 1 × –130) / 2 × 1
W = –3 ± √(9 + 520) / 2
W = –3 ± √(529) / 2
W = –3 ± 23 / 2
W = –3 + 23 / 2 or –3 – 23 / 2
W = 20/2 or –26/2
W = 10 or –13
Since measurement can not be negative, the width is 10 in.
Finally, we shall determine the length. This can be obtained as follow:
L = 3 + W
W = 10
L = 3 + 10
L = 13 in
SUMMARY
Length = 13 in
Width = 10 in

If you count all of the dots, you see that the total amount of math books is 12.
Then, look at the column between 2 and 2 2/8. You see that there are 2 books that weigh 2 1/8 pounds.
Therefore, there are 2 out of the 12 books that weigh 2 1/8 pounds.
2/12 can also be simplified down to 1/6.
Tell whether the angles are complementary or supplementary. Then find the value of x.
Answers
the angles are complementary because they add up to 90° because of the red square. x=20
Step-by-step explanation:
4x-5+15=90
4x+10=90 subtract 10 from each side
then you get left with 4x=80
divide 4 from each side then you get left with x=20 and to check just substitute 20 where x is so 4(20)-5= 80-5=75 +15=90.

She can expect to hit the bullseye 5 times.
Answer:
A. 5
Step-by-step explanation:
Regina throws 25 darts and hits the bullseye 20% of the time. So we would set up the equation as 0.20*25 (as we are looking for 20% of 25 and of means multiplication and 20% is 0.20). 0.20*5=5 so she can expect to hit the bullseye 5 times. Therefore, A is the correct answer choice.

Why might the method used be biased?
Asking every twentieth student does not accurately represent the student population.

Step-by-step explanation:
Area of a parallelogram is base x height
1st parallelogram:
The base is 8yd and the height is 12yd so ->
A = bh
A = 8 x 12
A = 96yd
2nd parallelogram:
The base is 7in and the height is 6in so ->
A = bh
A = 7 x 6
A = 42in
8*12= 96
7*6= 42
A triangle has angles measuring 43° and 62°. What is the measure of the triangle's third angle?
Answers
Answer:
75 degrees
Step-by-step explanation:
I know the measure of the triangle's third angle is 75 degrees because all the angles of a triangle add up to 180 degrees. So, I did 180-62-43 and got 75. So, in order for this triangle to be true, the third triangle would have to be 75 degrees.
To check: 43 degrees+ 62 degrees+ 75 degrees = 180 degrees.
