Step-by-step explanation:
x / 6 + 4 = 15
To find x ;
Subtrac4 from both sides
x / 6 + 4 - 4 = 15 - 4
x / 6 = 11

x / 6 * 6 = 11 * 6
x = 66
Value of x = 66
Answer:
solve using long division.
75/4
what is the largest whole number smaller than 75 that 4 can go into?
72.
how many times can 4 go into 72?
18.
so then subtract 72 from 75 to get 3.
the new equation is
3/4
how many times can 3 go into 4?
0.75 times.
so add the 2 answers to get
18.75
4 can go into 75 18.75 times.
10x^2-10x+20 is the answer to this
