Answer:
The inequality in therms of x is 
.
Patricia had bought at least <u>4 hair clips</u> of cost $0.15 each.
Step-by-step explanation:
Given:
16 hair clips = $3
hair clips = $0.15 each
hair clips = $0.20 each
We need to find the minimum number of hair clips of $0.15 that she bought.
Solution:
Now we can say that;
hair clips multiplied by $0.15 plus hair clips multiplied by $0.2 should be less than or equal to 3.
framing in equation form we get;
Hence The inequality in therms of x is .
Combining like terms we get;
Dividing both side by -0.05 we get;
Hence Patricia had bought at least <u>4 hair clips</u> of cost $0.15 each.
30 as in 30.0 or .30? Is there more to the question?
Answer:
$890.4
Step-by-step explanation:
840 + .06(840)
840 + 50.4
890.4
Answer:
Step-by-step explanation:
Find the volume first.
V= l * w * h
l = 2 cm
w = 3 cm
h = 1 cm
V = 2 * 3 * 1 = 6 cm^3
Density = mass / volume
Density = 420 grams / 6 cm^3
Density = 70 grams / cc^3
Kind of large. Check your givens.
Answer:
use a calculator
Step-by-step explanation:
also if this is easier change 1/2 and 1/3 to 0.5 and 0.3 where it would be 8.5 x 3.3
