A certain fraction has a value of 15. the denominator is four more than three times the numerator. what is the fraction?
ra1l [238]
N/d = 15
d= 4 + 3n

d=n/15
n/15=4+3n
n=60+45n
44n=-60
n=-15/11
-15/11 / d = 15
-15/11 = 15d
d=-1/11

15/11 / 1/11. = 15

5(5t + 1) = 25t-7<br> Can someone help me with this solution??
masha68 [24]
Firstly you multiply 5 with everything in the brackets on the left side of = . and than you put t on the left side and change sign (if it was + then its going to be -) and numbers on right side and do the same with signs. then just calculate the rest

5(5t +1) = 25t - 7
25t + 5 = 25t - 7
25t - 25t = -7 + 5
0=-2
the statement is false
