Is the percent increase from 50 to 70 equal to the percent
decrease from 70 to 50? Explain.
Answer:
No.
Summary reason:
While the positive difference is the same, the original number is not. You are comparing the following ratios 20/50 and 20/70 respectively. As we can see, these are different numbers so they represent different percentages.
Step-by-step explanation:
The question is asking is the the positive difference over the original the same in each one. While the positive difference is 20 in both, the original is different. This makes the percent changes different as 20/50 does not equal 20/70.
That is, I'm just doing
(Biggest-Smallest)/original .
So the first one we have increase of
(70-50)/50=20/50=2/5=.4=40%
So the second one we have a decrease of
(70-50)/70=20/70=2/7=approximately 28.6%.
As you can clearly see these percentages are not equal.
Answer:
Sample response: No. The amounts of change are the same, but the original amounts are different. The ratio for the percent increase from 50 to 70 is 20/50, or 40%. The ratio for the percent decrease from 70 to 50 is 20/70, or about 29%.

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
The number of small boxes in the right side of the equation = 10 boxes of 1
So , the value of A = 10
The number of small boxes in left side of the equation = 4 boxes of 1
The number of x in the equation = 3x
So , the equation is
3x + 4 = 10 be equation (1)
On simplifying the equation , we get
Subtracting 4 on both sides of the equation , we get
3x = 6
Divide by 3 on both sides of the equation , we get
x = 6/3
x = 2
Hence , the value of the equation is x = 2

How many groups of 3/4 are in each of the following quantities? 11/4, 6 1/2
There are complete 3 groups of 3/4 in 11/4.
There are complete 8 groups of 3/4 in 6 1/2.
To find the number of groups of 3/4 in 11/4, we divide it by 3/4.
[tex]\frac{\left(\frac{11}{4}\right)}{\left(\frac{3}{4}\right)}=3.67[/tex]
So there are complete 3 groups of 3/4 in 11/4.
To find the number of groups of 3/4 in 6 1/2, we divide it by 3/4.
[tex]\frac{\left(6\frac{1}{2}\right)}{\left(\frac{3}{4}\right)}=\frac{\left(\frac{13}{2}\right)}{\left(\frac{3}{4}\right)}=8.67[/tex]
So there are complete 8 groups of 3/4 in 6 1/2.

During the summer, Jody earns $10 per hour babysitting and $15 per hour doing yardwork. This week she worked 34 hours and earned $410. If x represents the number hours she babysat and y represents the number of hours she did yardwork, which system of equations models this situation?
A.
x + y = 34
10x + 15y = 410
B.
x + y = 410
10x + 15y = 34
C.
x + y = 34
15x + 10y = 410
D.
x + y = 410
15x + 10y = 34
Answer:
C! i’m sure off i hope i’m right
Step-by-step explanation:
Answer:
A. x+y=34
10x+15y=410
Step-by-step explanation:
First the question states that babysitting is represented by x and yard work is represented by y, so that eliminates C and D.
If x and y are the amount of hours put into babysitting and yard work you would make the equation, x+y=34 to find out how many hours of each were worked.
Then you would make the equation 10x+15y=410 with the known variables.
So in conclusion A is the correct answer.
