The ratio of the number of boys to the number of girls in a school is 5:7.If there are 600 students in the school,how many girls are there?
Answers
The secret to solving problems with ratios is to find the value of one unit.
5:7 = 12 units total
To find one unit, divide the total number of students by the total number of units.
600/12 = a
Simplify
50/1 = a
50 = a
The value of each unit is 50.
Now, multiply the units by the numbers in the ratio.
50(5) = b
250 = boys
50(7) = x
350 = x
There are 350 girls.

Mr. Murphy's calculation of the taxes they are to pay this year is wrong because a. He has calculated only federal taxes.
There are several taxes that an employed person must pay including:
- Federal income taxes
- Federal social security taxes
- State taxes
Mr. Murphy only calculated the federal taxes and did not include the state ones which are usually higher than the federal tax. Once he includes the state tax, his calculation will be correct.
In conclusion, state taxes need to be paid for as well.

Answer:
x = 20
Step-by-step explanation:
Starting equation: x - 36 + 12x = 224
Reorder: 12x + x (as there is no negative sign in front of the x) - 36 = 224
Add common terms: 13x - 36 = 224
Subtract (in this case add) common term to isolate variable: 13x + 36 = 224 + 36
Isolate variable by dividing both sides by 13: 13x = 260
Solve: x = 20
-5/6b = 30
Answers
Answer:
b = -36
Step-by-step explanation:
In other words, solve this given equation -5/6b = 30 for b.
For clarity we rewrite this as (-5/6)b = 30.
To isolate b, we multiply both sides of the above equation by (-6/5):
(-6/5)(-5/6)b = (30)(-6/5), or
b = -36

Answer:
1.6
Step-by-step explanation:
In order to find the distance all you need to do is subtract the two numbers
so you would:
-5.4-(-3.8)=-1.6 or 1.6 since distance is not negative number.
A interesting fact to note is when you are subtracting negatives you can also just add the number as a positive
Ex.
5 - (-2) =7
5+2=7
Final answer:
The distance between -5.4 and -3.8 is found by taking the absolute difference of these two numbers, which results in 1.6.
Explanation:
To find the distance between two numbers on a number line, we subtract the smaller number from the larger one and take the absolute value. Here, the smaller number is -5.4, and the larger number is -3.8. Therefore the absolute difference or distance between these two numbers would be |-5.4 - (-3.8)| which equals to |-5.4 + 3.8| = |-1.6|= 1.6. Hence, the distance between -5.4 and -3.8 is 1.6.
