To find out how many inches were gained, solve it with the expression 8 - x.
Answer:
2/3
Step-by-step explanation:
slope formula is ( y2 - y1 ) / ( x2 - x1)
so put in the values that are given to us
(5 - 3) / (-1-2)
= (2) / -3
= 2/3
39.37 in you would do 100 divided by 2.54
Answer:
Thank you very much LY
Step-by-step explanation:
Answer:
6 years and 15 years of age
Step-by-step explanation:
Given the ratio of their ages is 2 : 5 = 2x : 5x ( x is a multiplier )
Then in 9 years their ages are 2x + 9 and 5x + 9 in the ratio 5 : 8
By proportion
= ( cross- multiply )
5(5x + 9) = 8(2x + 9) ← distribute parenthesis on both sides
25x + 45 = 16x + 72 ( subtract 16x from both sides )
9x + 45 = 72 ( subtract 45 from both sides )
9x = 27 ( divide both sides by 9 )
x = 3
Thus
Rohit's age = 2x = 2( 3) = 6
James' age = 5x = 5(3) = 15
6 : 15 = 2 : 5
