If 45% of a number is 63 and 35% of the same number is 49, find 80% of that number.
Answer:
Step-by-step explanation:
1) Let the number be y
45%of y=63
45y/100=63
Y=6300/45
Y=140
So 80%of a number =80y/100
=80×140/100
=112.
Let the number be y
35%of y=49
35y/100=49
Y=4900/35
Y=140
So 80%of a number =80y/100
=80×140/100
=112.

A town’s population of children increased from 376 to 421 during the past year.
Which equation shows how to find the percent increase?
p=421−376376
p=421−376421
p=376421−376
p=376+421376
Answer: B
Step-by-step explanation:
Answer: see explanation
Step-by-step explanation:
percent increase = × 100%
the increase = 421 - 376 = 45, hence
percent increase = × 100% ≈ 12%

Step-by-step explanation:
why wuld 8/4 be considerd a whole number
Answer:
because 8/4=2
Step-by-step explanation:
4/4=1
8/4=2
it's because the numerator is bigger if it were 6/4 it would be a mixed number but the eight goes in to 4 directly 2 time so therefore it's 2.
Given that a = -1, b=2 and c= -3 ,find the value of a(b2+c2)
Answer:
a([tex]b^{2}[/tex]+[tex]c^{2}[/tex]) = = -13
Step-by-step explanation:
Given that a = -1, b=2 and c= -3
find the value of a([tex]b^{2}[/tex]+[tex]c^{2}[/tex])
Just substitute the values given for each variable
a([tex]b^{2}[/tex]+[tex]c^{2}[/tex]) = (-1)([tex]2^{2}[/tex]+[tex](-3)^{2}[/tex]) ; do the exponents first
a([tex]b^{2}[/tex]+[tex]c^{2}[/tex]) = (-1)(4+9)=(-1)(13) ; now add inside the parenthesis;
a([tex]b^{2}[/tex]+[tex]c^{2}[/tex]) = -13 ; and multiply by -1
Tristan charges a flat rate of $16 for
each small lawn that he mows. He
decided to increase his rate to $20.
What is the new rate as a percent of
the old rate? Show your thinking.
Answer:
125%
Step-by-step explanation: because 25% of $16 is $4 and it's a $4 increase of the already 100% making 125%
Trudy bought a $20 prepaid long distance phone card. for every minute that she talks, $0.25 is deducted from her card. The function f(m)=20-0.25m represents the amount of money f(m) she has left after talking m minutes.FInd the zero and explain what it means in the context of the situation.
Answer:
Step-by-step explanation:
Given the function f(m)=20-0.25m to represent the amount of money f(m) she has left after talking m minutes, the zero of the equation can be gotten by setting f(m) to 0
f(m)=20-0.25m
0 =20-0.25m
-20 = -0.25m
m = -20/-0.25
m = 80
Hence Trudy will have talked for 80minutes if she has no money left

In arithmetic, variables look like
Answer here
SUBMIT
Answer:
In arithmetic, variables look like letters.
Step-by-step explanation:
As we know that Mathematical arithmetic deals with numbers and certain properties with them.
Some of the main properties between numbers are as follows:
AdditionSubtractionMultiplicationDivisionVariables do not remain constant, so we basically assign a number to a variable with an equal operator denoted by '='.
For example, let us assume a variable x being equal to 7. so it can written as:
[tex]x = 7[/tex]
Let suppose the value of the variable x=7 changes to x=10, then the new value will be:
[tex]x = 10[/tex]
Therefore, the correct answer is:
In arithmetic, variables look like letters.

50 points brainliest answer
Answer: x = 160
Step-by-step explanation:
540 = 100+(x-25)+(x-15)+(1/2)x+(1/2)x
540= 100-40+3x = 60+3x
480 = 3x
x = 160
Answer:
0.5x + 0.5x + (x-25) + (x-15) + 100 = 540
x + x - 25 + x - 15 + 100 = 540
3x + 60 = 540
3x = 540 - 60
3x = 480
x = 480/3
x = 160
Solve for x and y
3x + 2y = 16
7x + y = 19

Step-by-step explanation:
A flat-screen television was marked down by 35 percent, which reduced its price by $115.65. What was the original cost of the television before it was marked down?
$214.78
$330.43
$404.78
$4,047.75
Answer:
B
Step-by-step explanation:
35% of this price is :
35/100 × x = 0.35x
The price reduces by 0.35x.
This equals to 115.65
Now :
0.35x = 115.65
100/35 × 115.65 = 330.43

Rita is adding 3 + (negative 8) + 1. She rewrites the expression as 3 + (negative 1) + 8. What is Rita’s error? She used the commutative property, which cannot be used with negative numbers. In the new expression, –8 and 1 should both be negative. She used the associative property which should only be used with positive numbers.. She switched the negative signs for –8 and 1.
She used the associative property which should only be used with positive numbers (sorry if it isn't the answer you're looking for)

Is 5/6 equal to 2/3?
=====================================================
Work Shown:
For now, let's assume they are equal. We'll show a contradiction happens.
5/6 = 2/3
5*3 = 6*2 ... cross multiply
15 = 12 ... here's the contradiction
If the original equation was true, then we would get the same thing on both sides in the final step shown above. However, we get a contradiction, so that means the original equation is false.
Furthermore, the left side is larger in the third step, so the left side is larger for each of the three steps. We can then say
5/6 > 2/3
5*3 > 6*2
15 > 12
Which helps show 5/6 is larger than 2/3.
---------------------
Or you can use a calculator to see that
5/6 = 0.833 approximately
2/3 = 0.667 approximately
which shows the two fractions aren't equal and 5/6 is larger.
