Answer:
the solution is x<-2
.
Step-by-step explanation:
each time you multiply both sides with a negative number or if you divide both sides by a negative number, you need to "turn" the greater/less sign, so, transform
<
into
>
and vice versa
if you flip the sides of the equation, you also need to "turn" the greater/less sign.
11.3x + 7.2 = 86.3
11.3x + 7.2 (-7.2) = 86.3 (-7.2)
11.3x = 79.1
11.3x/11.3 = 79.1/11.3
x = 7
7 is your answer

Answer:
2
Step-by-step explanation:
5 to the power of 4 is equal to 5 x 5 x 5 x 5, which equals 625.
5 to the power of 6 is equal to 5 x 5 x 5 x 5 x 5 x 5, which equals 15625
So the value of 5 to the power of 4 over (divide) 5 to the power of 6 is the same as 625 divided by 15625, which equals 0.04.
A shorter way is you can do this is to cancel like terms:
<span> <u> 5 x 5 x 5 x 5 </u></span><u> </u>
5 x 5 x 5 x 5 x 5 x 5
You can cancel 4 fives on the top with 4 of the 5's on the bottom and you are left with
<u> 1 </u>
5 x 5
or 1/25 which is also equal to 0.04.
Hope this helps.
Have a blessed day!
