12 ^3 and 11^3 haven't got the same base so the rules of exponents do not apply.
Bases have to be the same:- for example 12^3 * 12*3 = 12 ^(3+3) = 12^6
There you go... a. 10
If we add x to both sides, we get rid of the x on the right side which leaves us 1/2x + 2 = 7. (1/2=0.5)
Then if we substract 2 from both sides, we will get 1/2x = 5
If half of x = 5, then the whole of x = 10.
Answer:
4 over 5
Step-by-step explanation:
The simplist form of 8/10 is 4/5.
Answer:
y<3
Step-by-step explanation:
It is y<3 because all areas below y=3 are shaded.
In addition, the line y=3 is dotted, which means it is not part of the inequality (i.e. strict inequality).
If it had been a full line, then it would be y<=3.
