Answer:
x = 7
y = 12
Step-by-step explanation:
Here, we want to get the values of x and y
All we have to do is to evaluate what we have on the left
By indices, since the bases are same, we simply add up the powers
so we have;
1/3 + 1/4
= (4 + 3)/12 = 7/12
Thus, x = 7 and y = 12
Answer:
(x) = x + 8
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = 9(x - 8) ← divide both sides by 9
= x - 8 ( add 8 to both sides )
+ 8 = x
Change y back into terms of x with x = (x) , thus
(x) = x + 8
Answer:
Write the expression as:"
70 + 2 * 2 − 18a " ;
______________________________________________________or; write as:
______________________________________________________ "
70.32 + (2.1) * (2.7) − 18a " ;
______________________________________________________To simplify:
______________________________________________________ Using "PEDMAS" (the "order of operations") ;
the "multiplication" comes first;
So: → "(2.1) * (2.7) = 5.67 " .
And rewrite:
______________________________________________________ " 70.32 + 5.67 − 18a " .
Now: " 70.32 + 5.67 = 75.99 " ;
So, we can the final simplified expression as:
______________________________________________________ "
75.99 − 18a " ;
or; write as: "
75 − 18a " .
