Answer:
n = 18
Step-by-step explanation:
2n - 5 = 31
Add 5 to each side
2n - 5+5 = 31+5
2n = 36
Divide each side by 2
2n/2 = 36/2
n = 18

Multiply simplified answer and give as a mixed number
6 3/5 multiply by 2 1/4
Answer:
[tex]14\frac{17}{20}[/tex]
Step-by-step explanation:
[tex]6\frac{3}{5} (2\frac{1}{4})\\\\\frac{33}{5} (\frac{9}{4} )\\\\\frac{297}{20} = 14\frac{17}{20}[/tex]
Answer:
14 17/20
Step-by-step explanation:
Convert the mixed numbers to improper fractions first.
So 6 3/5 =33/5 and 2 1/4 =9/4
Then multiply 33/5 x 9/4
33 x 9=297
5 x 4 =20
Then convert 297/20 back to a mixed number by dividing
14 x20 =280
you have 17/20 left
Is 2(x-y) and 2x-2y equivalent
Answer:
Yes
Step-by-step explanation:
Start with the 2(x-y) and distribute the 2 to each term
2(x)-2(y)
This would equal
2x-2y
Which matches the second equation making the answer yes.
The pairs of expressions that are equivalent are:
- [tex]\( 2(x-y) \)[/tex] and [tex]\( 2x-2y \)[/tex]
- [tex]\( 4(x+y) \)[/tex] and [tex]\( 4y+4x \)[/tex]
- [tex]\( 21q-7p \)[/tex] and [tex]\( (3q-p)(7) \)[/tex]
Let's simplify each expression to see if they are equivalent.
Step 1
1. [tex]\( 2(x-y) \)[/tex] and [tex]\( 2x-2y \)[/tex]:

Yes, they are equivalent.
Step 3
3. [tex]\( 21q-7p \)[/tex] and [tex]\( (3q-p)(7) \)[/tex]:
Simplifying [tex]\( (3q-p)(7) \)[/tex]:
[tex]\[ (3q-p)(7) = 21q - 7p \][/tex]
Yes, they are equivalent.
Step 4
4. [tex]\( 4(2a-3v) \)[/tex] and [tex]\( 8a+6v \)[/tex]:
Simplifying [tex]\( 4(2a-3v) \)[/tex]:
[tex]\[ 4(2a-3v) = 8a - 12v \][/tex]
No, they are not equivalent.
Step 5
5. [tex]\( 8(3x+c)-1 \)[/tex] and [tex]\( 8c+24x-1 \)[/tex]:
Simplifying [tex]\( 8(3x+c)-1 \)[/tex]:
[tex]\[ 8(3x+c)-1 = 24x + 8c - 1 \][/tex]
No, they are not equivalent.
Step 6
6. [tex]\( 4p+3c \)[/tex] and [tex]\( (c+2p)(2) \)[/tex]:
Simplifying [tex]\( (c+2p)(2) \)[/tex]:
[tex]\[ (c+2p)(2) = 2c + 4p \][/tex]
No, they are not equivalent.
[tex]\( (3q-p)(7) \)[/tex]

Solve the following:
a)X + 5 = 11
b) X- 6 = 8
c) 3 + x = 7
d) 12 = x + 5
Answer:
Step-by-step explanation:
a) X + 5 = 11
Subtract 5 from both sides
X = 6
b) X - 6 = 8
Add 6 on both sides
X = 14
c) 3 + X = 7
Subtract 3 on both sides
X = 4
d) 12 = X + 5
Subtract 5 from both sides
7 = X or X = 7
Answer:
a) x=6
subtract 5 from each side.
b) x= 14
add 6 to each side
c) x=4
subtract 3 from both sides
d) x=7
subtract 5 from both sides
Step-by-step explanation:
a) subtract 5 from each side.
b) add 6 to each side
c) subtract 3 from both sides
d) subtract 5 from both sides

What is the Pythagoras theorem?Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a² + b² = c².
Given here, Sin C = x/1 and therefore Hypotenuse = 1 and perpendicular =x
thus Base=1-x² by phytogaraen theorem.
Thus Sin A=1-x² /1
Hence, Sin A= 1-x² is the correct answer.

17 35/50
Answer:
17.7
Step-by-step explanation:
First off, we do not need to do anything to the 17, it is already set up for a decimal. So we have to find out how much 1/50 is so we divide:
Divide:
1/50=0.02
Multiply by 35:
0.02 times 35= 0.7
Add the 17:

f(x)=-x^2+x
f(x)=−x
Find f(−1)
Answer:
Step 1: Set x to -1 in the first equation
[tex]f(x) = -x^2 + x[/tex]
[tex]f(-1) = -(-1)^2 + (-1)[/tex]
[tex]f(-1) = -(1) - 1[/tex]
[tex]f(-1) = -1 - 1[/tex]
[tex]f(-1) = -2[/tex]
Step 2: Set x to -1 in the second equation
[tex]f(x) = -x[/tex]
[tex]f(-1) = -(-1)[/tex]

Factor this expression: 40-100m
Answer:
10(4-10m)
Step-by-step explanation:
You have to find something that can go out of both of the numbers.
10 is the highest that i could find.
So you basically have to put the number on the outside of the racks.
Then divide it.
40-100m
÷10 ÷10
whats left is 4-10m
The variable can't be divided with it since it doesn't have another variable to go with.
The expression '40 - 100m' can be factored by finding a common number, which, for 40 and 100, is 20. On factorizing the expression we get: '-20(2 - 5m)'.
Explanation:The expression '40 - 100m' can be factored by finding a common number that both 40 and 100 can be divided by. This number is 20, but since we also have -100m, we'll use -20. Therefore, the factored form of '40 - 100m' is '-20(2 - 5m)'. Here is the step-by-step process.
Identify numbers that both 40 and 100 can be divided by evenly; in this case, 20.
Factor out the common number from the original expression, which gives '-20(2 - 5m)'.

Find the area(now I need to make this 20 words longfheieh)
Given:
Image of the figure
To find:
The area of the figure.
Solution:
The image is splitted into two shapes.
One is rectangle and the other is trapezium.
Reference image for answer is attached below.
Rectangle:
Length = 10 cm
Width = 2.8 cm
Area = length × width
= 10 × 2.8
Area = 28 cm²
Trapezium:
Top base = 6 cm
Bottom base = 10 cm
Height = 7.2 - 2.8 = 4.4 cm
Area = [tex]\frac{1}{2} \times(b_1+b_2)\times h[/tex]
[tex]$=\frac{1}{2} \times(6+10)\times 4.4[/tex]
[tex]$=\frac{1}{2} \times16\times 4.4[/tex]
Area = 35.2 cm²
Area of the figure = 28 cm² + 35.2 cm²
= 63.2 cm²
The area of the figure is 63.2 cm².

To find the percent divide the number who will vote for Candidate A over the total number of people surveyed
vote for Candidate A/total surveyed
128/240=0.53333
0.53333*100=53.3333%

the lengths of three
sides of a triangle are
in the extended ratio
3: 6: 8. the perimeter
of the triangle is 5.1m
What are the lengths
of the sides in cm?
.
Answer:
90 cm, 180 cm, 240 cm
Step-by-step explanation:
Let the lengths of sides of the triangle be 3x, 6x and 8x
[tex] \therefore \: 3x + 6x + 8x = 5.1 \: m \\ \therefore \: 17x = 510 \: cm \\ \therefore \: x = \frac{510}{17} \\ \therefore \:x = 30 \: cm \\ \implies \\ 3x = 3 \times 30 = 90 \: cm \\ 6x = 6 \times 30 = 180 \: cm \\ 8x = 8 \times 30 = 240 \: cm[/tex]
Hence, lengths of the sides of the triangle are 90 cm, 180 cm and 240 cm.
