-17+ 1/4 x + 1/4 x + 31 = 24
______________________________
1.) Combine like terms:[tex]\frac{1}{4}x+\frac{1}{4}x=\frac{1}{2}x[/tex]
- We do this because we need 1 Number/Variable left over.
Equation at the end of Step 1:
[tex]-17+\frac{1}{2}x+31=24[/tex]2.) Add −17 and 31:[tex]-17+31=14[/tex]
- We do this because we can only have 1 number on each side of the equals. (This doesn't count towards the number connected to the variable.)
Equation at the end of Step 2:
[tex]14+\frac{1}{2}x=24[/tex]3.) Subtract 14 from both sides:[tex]14-14=[/tex] Cancels Out[tex]24-14=10[/tex]
- We do this because now we just need the 1 variable and the 1 number on opposite sides of the equal.
Equation at the end of Step 3:
[tex]\frac{1}{2}x=10[/tex]4.) Multiply both sides by 2:[tex]\frac{1}{2}x[/tex] × [tex]2=x[/tex][tex]10[/tex] × [tex]2=20[/tex]- We multiply by 2 since we have a fraction. In this case the reciprocal is 2 meaning we multiply by 2.

The equation y = 3.5x represents the total cost y in dollars of buying x pounds of cheddar cheese at Art’s Deli. The graph below shows the total cost y in dollars of buying x pounds of cheddar cheese at Jon’s Deli. What conclusion can you draw about the cost of cheddar cheese at these delis? Cheddar cheese costs $4 more per pound at Jon’s Deli than Art’s Deli. Cheddar cheese costs $0.50 more per pound at Jon’s Deli than Art’s Deli. Cheddar cheese costs $3.50 less per pound at Art’s Deli than Jon’s Deli. You pay the same price per pound for cheddar cheese at both delis.

Scrat the squirrel has a few nuts. When he put them in groups of 5 nuts, two nuts were left, and
when he laid them out in groups of 3 nuts, there were no nuts left. How many nuts among the
options provided below could belong to Scrat?
Answer:
The options are not shown, so i will solve this in a general way.
Let's suppose that there are N nuts
If we divide the N nuts into groups of 5, there will be a remainder of 2 nuts.
If we divide the N nuts into groups of 3, there is no remainder.
This means taht N is a multiple of 3. then we can write:
N = 3*k
where k is a random integer.
Now, we know that when we divide N by 5, there is a remainder of 2 nuts, this means that N is equal to a multiple of 5 plus 2, then we can write:
N = 5*j + 2
where j is a random integer.
Now we only need to find a pair of k and j (both positive integers) such that:
3*k = 5*j + 2
We can rewrite this as:
k = (5/3)*j + (2/3)
Now we could just input different values of j, and see if k is also an integer:
j = 2
k = (5/3)*2 + 2/3 = 10/3 + 2/3 = 12/3 = 4
Then the pair j = 2, k = 4 is a possible solution.
N = 3*k = 3*4 = 12
N = 5*j + 2 = 5*2 + 2 = 12
From this we can conclude that N = 12, so Scrat has 12 nuts.
Now with the equation
k = (5/3)*j + (2/3)
We can find other possible combinations of j and k, that will give different values for N.
for example, if j = 5:
k = (5/3)*5 + 2/3 = 25/3 + 2/3 = 27/3 = 9
Then the pair j = 5, k = 9 is also a possible solution:
N = 3*k = 3*9 = 27
N = 5*j + 2 = 5*5 + 2 = 27
In this case, Scrat has 27 nuts.

1/3 of 30 = 10
10 + 10 = 20
Jared buys 2.4 pounds of broccoli for $3.24. Which equation could Jared use to find c the
cost of each pound of broccoli?
2.4 +c= 3.24
2.4c = 3.24
3.24c = 2.4
3.24 + c = 2.4

QRINC offered new employees a starting salary of $34,862 in 2013. What would a comparable starting salary have been in 2003?
Answer:
[tex]C=27535.5881128[/tex]
Step-by-step explanation:
From the question we are told that
CPI for 2003(index)=2003-184.00
CPI for 2013(index)=2013-232.957
Starting salary in 2013 at $34,862
Generally comparable starting salary C is given as
[tex]C=\frac{starting salary}{CPI for 2013(index} *CPI for 2003(index)[/tex]
[tex]C=\frac{34,862}{232.957} *184[/tex]
Therefore C the comparable starting salary is givrn to be
[tex]C=27535.5881128[/tex]
[tex]C=27536 appro[/tex]
In parallelogram GHJK if m KGH=25° find mJKG.
H

xº
K
Answer:
Submit Answer
attempt 1 out of 3
Answer:
x = 155°
Step-by-step explanation:
Adjacent angles of a parallelogram are supplemenary angles . Supplemwntary angles are the angles whose sum is 180°. So,
KGH + JKG = 180°
=> 25° + x° = 180°
=> x = 180 - 25 = 155°

In one class, there are 2 of every 8 students in the class chewing
gum. If there are 32 students in the class, how many students are
chewing gum?
Answer:
8
Step-by-step explanation:
Answer:
8 people are chewing gum
Step-by-step explanation:
32/8=4, meaning there are 4 sets of 8 students.
If 2 students are chewing gum for every 8, and there are 32 students, that would mean that multiplying 4 by 2 to get 8 total kids chewing gum.
You could also say that 6*4=24, and 32-24=8 if you want to double check.
Hope this helps :)

The athletic departments at 10 randomly selected U.S. universities were asked by the Equal Employment Opportunity Commission to state what percentage of their nursing scholarships were presently held by women. The responses were 5, 4, 2, 1, 1, 2, 10, 2, 3, 5. what is the midrange
Answer:
5.5
Step-by-step explanation:
Given the set of data
5, 4, 2, 1, 1, 2, 10, 2, 3, 5.
The average of the least and the greatest value is known as the midrange
The formula for calculating the midrange is expressed as shown:
Midrange = (Greatest value + Least value)/2
Given
Greatest value = 10
Least value = 1
Midrange = 10+1/2
Midrange = 11/2
Midrange = 5.5
Hence the midrange of the data is 5.5
