3.10/155= 0.02 } subtract = 0.07 more
7.65/85= 0.09 }
Since 6 is greater than 5 you input it into the last equation!
2•(6^2) -7
2•(36) -7
72 -7
65
The answer is 65!
First we will find out the values of a
a/4=b/7
a=4b/7
Now
(a-b)/b
{4b/7-b}/b
(4b-7b)/7b
-3b/7b
-3/7
7x + 5 = 8x
=》 7x - 8x = - 5
=》 x = - 5 The final Answer!
