Answer:
122
Step-by-step explanation:
We are finding the difference, so our equation will be
[tex]82 - (-40)[/tex]
Subtracting by a negative is basically the same as adding. (- & - = +)
[tex]82 - (-40) =82 + 40[/tex]
Now add 82 + 40
[tex]82[/tex]
+ [tex]40[/tex]__
122
Hope this helps! If you have notes try writing out the steps for how to solve. :))

Answer:
55w + 145
Step-by-step explanation:
Total = all accounts, so you have to add 10w to 45w, and 120 to 25
10w + 45w = 55w
120 + 25 = 145
So the answer is 55w + 145

Answer:
-2.5
Step-by-step explanation:
It is the answer of the first question.
10. If R is the midpoint of QS, find QS.
Statement:
R is the midpoint of QS.
To find out:
The measure of QS.
Solution:
QR + RS = QSSince R is the midpoint of QS, then QR = RS.QR = 2x + 16, RS = 5x - 17.Therefore, 2x + 16 = 5x - 17or, 2x - 5x = -17 - 16or, -3x = -33or, x = -33 ÷ -3or, x = 11Therefore, QR = 2(11) + 16= 22 + 16 = 38So, QS = 2QR = 2 × 38= 76Answer:
QS is 76.
Hope you could understand.

Benita buys 2 shirts for the same price s the taxe sale rate is 6.5%
Answer:
2s + 0.13s
2.13s
Step-by-step explanation:
One shirt costs s.
2 shirts cost 2s.
The tax rate is 6.5%, so the tax on 2s is 0.065 × 2s = 0.13s
The total cost with tax is 2s + 0.13s
You can also find the total cost by realizing that since the tax is 6.5%, the total price with tax is 1.065 times the cost, so you can write it as 1.065 × 2s = 2.13s
Answer:
2s + 0.13s
2.13s
Answer:
2.13s
and
2s+0.13s
Step-by-step explanation:
Because 2 shirts is s and 6.5 per cent would turn into 6.5 because of 2 times 1.065 is 0.13 which is the answer for part 2
Find the area and perimeter.
A^2 b 3a^2 a^2 4b
Answer: Area - 17a^2 b, Perimeter - 10a^2 + 10 b
Step-by-step explanation:
To find the area, we can divide the figure into 3 separate rectangles.
Then, we find the area of each separate rectangle and add them together.
Area = a^2b + a^2b + 15a^2b
Area = 17a^2 b
The perimeter is the sum of all sides
Perimeter = a^2 + b + 3a^2 + b + a^2 + 4b + 5a^2 + 4b
Perimeter = 10a^2 + 10 b

Please help me!!! Bsbebabnababwbabs
Step-by-step explanation:
since the other angles are equal to each other, both triangles, TQR and TSR, are identical. they are just oriented differently.
but that also means that both angles, Q and S, are identical too.
so,
2x² = 3x² - 64
64 = x²
x = 8
and therefore, both angles are 128°.
A box of bananas was bought for $50 and was sold for a 15% loss. What is the selling price of the bananas?
Answer:
$42.50
Step-by-step explanation:
when you have a percent loss you can take that number and subtracted from 100 and get your percentage
you multiply the amount by 85 percent
so this means it is 50 titimes 0.85
this gives me $42.5

Triangle QRS ~ Triange TUV. solve for x and y
Answer:
x = 20, y = 3
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are in proportion, that is
[tex]\frac{TU}{QR}[/tex] = [tex]\frac{UV}{RS}[/tex] ( substitute values )
[tex]\frac{x}{4}[/tex] = [tex]\frac{30}{6}[/tex] = 5 ( multiply both sides by 4 )
x = 20
and
[tex]\frac{QS}{TV}[/tex] = [tex]\frac{RS}{UV}[/tex] ( substitute values )
[tex]\frac{y}{15}[/tex] = [tex]\frac{6}{30}[/tex] ( cross- multiply )
30y = 90 ( divide both sides by 30 )
y = 3

10. 8 fewer than the sum of 14 and a number
Answer:
6 +x
Step-by-step explanation:
Let the number = x
Sum of 14 and a number = 14 +x
8 fewer than (14 + x )= 14 + x - 8 = 6 +x
Answer: 14 + x - 8 (can also be 6 + x)
Step-by-step explanation:
8 fewer means we're subtracting 8, which is -8
Sum of 14 and a number would be 14 + x
All of this combined would be 14 + x - 8 but if you want to simplify it, you can subtract 8 from 14 and get 6. This would be 6 + x.

Answer:
a) 0.11
b) 60
Step-by-step explanation:
a)
Probability that a 3 will be rolled = frequency of 3 / total frequency
frequency of 3 = 11
total frequency = 100; 12 + 35 + 11 + 23 + 7 + 12 = 100
= 11/100
= 0.11
Answer: 0.11
b)
Probability of getting 6 = 12/100 = 0.12
Now, the dice is rolled over 500 times:

The base of an isosceles triangle is 30” and the altitude to that base is 8”. Find the length of one of
the two equal sides of the triangle.
please help!
Answer:
17"
Step-by-step explanation:
Isosceles means there are two equal sides in this triangle.
So the height not only is perpendicular to the base, but also cuts the base in half.
Each half is 15 inches. (30÷2=15) See image.
These half triangles formed by the height, are right triangles. You can use Pythagorean theorem or if you're familiar with the pythagorean triple 8, 15, 17, you will find the length of the side is 17 inches. See image.

What is division. Please explain it very well
Answer:
Division is the separation of something (a number) into equal parts.
Step-by-step explanation:
Division is the separation of something (a number) into equal parts. In other words, it's the opposite of multiplication, which is the repeated addition of something (a number).
Probably the best way to explain division is with an example. Say I want to compute the following:
10 / 2
"10" means I have 10, and the "/ 2 means" that I want to seperate 10 into equal groups of 2. To do that, I will count how many groups of 2 I can have in 10. 2, 4, 6, 8, and 10 make 5 equal groups of 2. Therefore,
10 / 2 = 5.
Division can also result in remainders, or leftovers after division. This is because somethimes, numbers don't divide evenly. Take for instance this example:
10 / 3
I know that 3 isn't a multiple of 10, but I can still attempt to divide it. 3, 6, 9, three groups ... wait ..., I have only 1 left. What do I do with this 1? Well, it is a remainder now because it is left over:
10 / 3 = 3 and a remainder of 1 ( or 3 r1).
I'm sorry if this is a bad explanation, but I am not a big fan of using visuals online when teaching math. Yet, I have done my best to explain what division is (in abstract form no less), and I hope you can figure it out if you haven't yet in the future.
Write the equation of a line parallel to the line y = 3x+5 and passes through the point (-7, 2)
Answer:
y=3x+23
Step-by-step explanation:
Parallel lines have the same slope, so we basically keep the same equation, but we find the new y-intercept so it accounts for (-7,2):
y = 3x + b
2 = 3(-7) + b
2 = -21 + b
23 = b
Therefore, your equation would be y=3x+23
What equivalent ratios goes with 40:28
Answer:

Answer:
2.
Step-by-step explanation:
If it was 14, 24.5, or 28, that side of the trapezoid would've been much longer.
Answer:
I believe your answer would be 2
Step-by-step explanation:
Using the same method as I explained in your previous triangle question I assumed the bigger quadrilateral is an expanded version of the smaller one.
Step 1:
Divide 14 by 4
14/4=3.5
Step 2:
Divide 7 by your 3.5
7/3.5=2
This means that the side of x should be 2 because each side is squished by a factor of 3.5 and expanded by this factor to get to the big shape.
Hope this helps! :)
