Answer:

Step-by-step explanation:

Isolate the parts of the equation with the x variable

When you divide or multiply by a negative number in inequalities, you must flip the sign of the inequality.
Answer:
$225.50 (nearest cent)
Step-by-step explanation:
1 foot ≈ 0.3048 m
Width of room = 15 ft ≈ 15 x 0.3048 = 4.572 m
Length of room = 18 ft ≈ 18 x 0.3048 = 5.4864 m
Area of room = width x length = 4.572 x 5.4864 = 25.0938208... m²
Cost of carpet = $8.99 per m²
Total cost of carpet = 25.0938208 x 8.99 = $225.50 (nearest cent)
Answer:
400 red boxes were sold
Step-by-step explanation:
Step 1: Our output value is 2000.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above,2000=100%.
Step 4: Similarly, x=40%.
Step 5: This results in a pair of simple equations:
2000=100%
x=40%(2)
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
2000/x = 100%/40%
Step 7: Again, the reciprocal of both sides gives
x/2000 = 40%/100%
x=800
Therefore, 40% of 2000 is 800
and to find 50% just divide by 2
Its easy there are 6 sides that are equal so, 6 x 6 is 36 and thats the awnser, 36 your welcome!!!!! Hope this helps
Domain:

As we see in a numerator we have a square, so

is always 0 or more. Now, there are two possibilities:
1.

We divide two numbers, and first one is positive, so the result will be also positive (it canot be 0 in this case) when

. So:

2.

In this case the result wil be 0 (we have ≥ 0 in our inequality, so it will be a solution).

So the solution to this inequality is:
