There is no solution I believe since 2/3 and 8/10 cross multiplied are 2 times 10 and 3 times 8 which is 20 = 24 which does not equal and there is no answer
THE NUMBER WOULD BE -160. One-fourth of -160 is -40, and -40 decreased by 10 would be -150, because ( -40 - 10 = -50. ) It's quite simple. All you had to do was find a number that, when multiplied by 4, would equal a number that when decreased by 10 would be -50.
Answer:
46
Step-by-step explanation:
You need just substitute values of x and y, and calculate.
24x - 13y = 24*3 - 13*2 = 72 - 26 = 46
Remark
The idea here is to take any two successive terms and divide one by the other. which is the divisor and which the dividend will be discussed below.
Step One
Set up the ratio for the common ratio between terms that come one after another.
Mathematically this is written as
r =
So just to see how this looks
t_(n + 1) = 3
t_n = 9
r =
r = 1/3
Does this work for other examples? Let's try a more complicated looking one.
t_(n) = 1/9
t_(n+1) = 1/27
r = t_(n + 1) / t_n
r =
r =
r = 1/3
