Answer:
[tex]\frac{17}{24}[/tex]
Step-by-step explanation:
Step 1 :
4 - 1 [tex]\frac{3}{5}[/tex] = 2 [tex]\frac{2}{5}[/tex]
Step 2 :
1 ÷ 2 [tex]\frac{2}{5}[/tex] = 1 × [tex]\frac{5}{12}[/tex] = [tex]\frac{5}{12}[/tex]
Step 3:
[tex]\frac{2}{3}[/tex] + [tex]\frac{5}{12}[/tex] = [tex]\frac{8+5}{12}[/tex] = [tex]\frac{13}{12}[/tex] = 1 [tex]\frac{1}{12}[/tex]
Step 4:
3 ÷ [tex]\frac{13}{12}[/tex] = 3 × [tex]\frac{12}{13}[/tex] = [tex]\frac{36}{13}[/tex] = 2 [tex]\frac{10}{13}[/tex]
Step 5:
1 - 2 [tex]\frac{10}{13}[/tex] = - 1 [tex]\frac{10}{13}[/tex] = - [tex]\frac{23}{13}[/tex]
Step 6:
1 - [tex]\frac{16}{39}[/tex] = [tex]\frac{23}{39}[/tex]
Step 7:
[tex]\frac{23}{39}[/tex] ÷ ( - [tex]\frac{23}{13}[/tex] ) = - [tex]\frac{23}{39}[/tex] × [tex]\frac{13}{23}[/tex] = - [tex]\frac{1}{3}[/tex]
Step 8:
[tex]\frac{3}{8}[/tex] - ( - [tex]\frac{1}{3}[/tex] ) = [tex]\frac{3}{8}[/tex] + [tex]\frac{1}{3}[/tex] = [tex]\frac{9+8}{24}[/tex] = [tex]\frac{17}{24}[/tex]

The Venn diagram for given situation is as shown below.
The number of students who study exactly one subject = 56
What is set?"It is a collection of well-defined elements"
What is Venn diagram?"It is a pictorial representation that uses circles to show the relationships among sets."
For given example,
We have been given the data for 120 mathematics students at a college concerning the languages French, German, and Russian
Let set A, B and C represents the number of students who study French, German and Russian respectively.
⇒ n(A) = 65
⇒ n(B) = 45
⇒ n(C) = 42
20 study French and German
⇒ n(A ∩ B) = 20
25 study French and Russian,
⇒ n (A ∩ C) = 25
15 study German and Russian.
⇒ n(B ∩ C) = 15
8 study all three languages.
⇒ n(A ∩ B ∩ C) = 8
So, the Venn diagram for given situation is shown below.
Now, we find the number of students who study exactly one subject.
28 students study French only, 18 students study German only and 10 students study Russian only.
So, the total number of students who study exactly one subject is,
28 + 18 + 10 = 56
Therefore, 56 students study exactly one subject

what equation is equivalent to 7-2x=5
Answers
Answer:
x = 1New equation: 7 - 2 = 5Step-by-step explanation:
7 - 2x = 5=> 7 - 5 = 2x=> 2 = 2x=> x = 1Conclusion:
Since:
x = 1Our new equation will be 7 - 2 = 5
Hoped this helped.
Hey there!
7 - 2x = 5
-2x + 7 = 5
SUBTRACT 7 to BOTH SIDES
-2x + 7 - 7 = 5 - 7
CANCEL out: 7 - 7 because that gives you 0
KEEP: 5 - 7 because it helps solve for the x-value
NEW EQUATION: -2x = 5 - 7
SIMPLIFY IT!
-2x = -2
DIVIDE -2 to BOTH SIDES
-2x/-2 = -2/-2
CANCEL out: -2/-2 (on the LEFT SIDE) because that gives you 1
KEEP: -2/-2 (on the RIGHT SIDE) because it helps you solve for the x-value
NEW EQUATION: x = -2/-2
SIMPLIFY IT!
x = 1
Therefore, your answer should be: x = 1
Checking to make sure it is correct!
-2x + 7 = 5
-2(1) + 7 = 5
-2 + 7 = 5
So, this makes this statement TRUE
Good luck on your assignment and enjoy your day!

A customer purchased 3 pairs of jeans for $94.50. If each pair of jeans costs the same amount, write an equation and then solve for the amount a single pair of jeans costs
Answers
Answer:
One pair of jeans will cost $31.50
Step-by-step explanation:
To find how much one pair of jeans will cost let's write an equation
where the cost of one pair of jeans is x
∴ 3×x=94.50
to find x we will divide both sides by 3
∴3÷3×x=94.50÷3
which makes the equation
∴x=31.50
meaning that one pair of jeans costs $31.50
94.50=3*x
solve for x
94.59/3=x
31.50=x
each pair of jeans will cost $31.50

Answer:
2.3
Step-by-step explanation:
First we must get rid of the exponent, which is that little 3 at the top.
To do this, we will do:
(-2) × (-2) × (-2) = -8
Now we have -8 + 3.4, which equals -4.6
Next we will combine the numbers in the denominator, to get -2.
Now, all together, we have -4.6/-2.
Last but not least, we will divide -4.6 by -2, to get 2.3
And that's your answer, hope this helps you :)

at the beginning of year 4, only 3 years have elapsed, the 4th year hasn't started yet, since it's at the beginning, so at the beginning of year 4 we can say only 4-1 years have elapsed.

Answer:
D The value of the 2 in 12.5 is 1,000 times the value of the 2 in 0.912
Step-by-step explanation:
The value of a digit in a number can be found by setting the other digits to zero.
The value of 2 in 12.5 is 2.
The value of 2 in 0.912 is 0.002.
The ratio of values is 2.000/0.002 = 2000/2 = 1000.
The value of 2 in 12.5 is 1000 times the value of 2 in 0.912.
