Following bidmas/bodmas rules, you would divide, then multiply, then add and then lastly subtract
Answer:
The total of all the boxes would be $5.00.
You've got a nice 66 sitting right in the middle of that left side, so wouldn't it be nice if you could get rid of everything else? Well, with a little division and multiplication, we can!
7 7 6 6 5 5 → (7 ÷ 7) × 66 × (5 ÷ 5) = 1 × 66 × 1 = 66
As y varies inversely with x, we have a function of the form:
y = k / x
We must find the value of k:
For this we substitute y = 5 when x = 5.
We have then:
5 = k / 5
k = 5 * 5
k = 25
Then, the function is:
y = 25 / x
Answer:
the inverse variation function is:
y = 25 / x
Answer:
x > -1
Step-by-step explanation:
Divide the whole inequality by 9.
(+1)>
Subtract 1.
> - 1
> -
Multiply by 3.
x > -1
