A you can use it because it allows you to divide the 925 easier to make the question 10 times easier than it would be
Step-by-step explanation:The answer is 2
Answer:
the girls be 12 and boys be 48 respectively
Step-by-step explanation:
The computation of the number of boys and number of girls is shown below:
Let us assume A be girls
And, b be boys
According to the question
b = 4 × a
b - 8 = 2 × (a + 8)
b - 8 = 2 × a + 16
4 × a -8 = 2 × a + 16
4 × a - 2 × a = 16 + 8
2 × a = 24
a = 12
Now
b = 4 × a
= 4 × 12
= 48
Hence, the girls be 12 and boys be 48 respectively
Two supplementary angles are in the ratio 3:7. Find the angles ?
Let the two angles be 3x and 7x.
Supplementary angles add up to 180 degrees.
Therefore:
3x + 7x = 180
10x = 180
x = 18
3x = 3 * 18 = 54
7x = 7 * 18 = 126
Answer: 20/3
So when solving this equation first distribute our 3,we will now have 3x-15=5.
Next we will Add 15 to both sides of our equation. Now we have 3x=20.Then divide our terms,and you will have 3x/3 = 20/3
<u>This will leave you with 1x=20/3. </u>
So the X is 20/3.
Hope that helped!
