1/4 of the school is boys
1/2 of 1/4 is 1/8
2/3 of 3/4 is 5/12
1/4 of boys and 5/12 of girls are there
330 people are at the event
If 3/4 of the school is there, then there are 440 people in school
X=0
you use the slope formula (y2-y1) divided by (x2-x1) to get (10-0)=(5-x)
x has to be 0.
Answer:
Son's age is 25.
Step-by-step explanation:
Let the Father's age be 2x.
Let the son's age be x.
Five years ago:
Man's age will be = 2x - 5
Son's age will be = x - 5
If the ratio of their ages five years ago was 9:4, then:
2x - 5/x-5 = 9/4
⇒ 4(2x - 5) = 9(x - 5)
⇒ 8x - 20 = 9x - 45
⇒ -20 + 45 = 9x - 8x
⇒ 25 = x
∴ x = 25
Hence, the son's age = 25 years
If x = 25, the father's age (2x) will be 2 × 25 = 50 years
Answer:
Step-by-step explanation:
6/5.
You need to use y=mx+c to answer this so basically
gradient/slope (m) is 1.5 and the y-intercept (c) is -2
Hope this helps :)
