Answer:
#13: 2.23×10⁻³ kg/cm³
#14: 10.23 ft²
Step-by-step explanation:
Good on you for thinking something wasn't right! Those conversions they gave you are correct, but the length conversions just aren't in the correct dimensions. In #13 you need cm² and in #14 you need ft³. To do this, you simply square or cube both sides of the conversions (because what you do to one side must be done to the other). Then you'll end up with conversions for two or three dimensional measurements. I have an attachment that shows my work, but I'll put an example here as well.
If 1in = 2.54 cm, then:
- (1 in)² = (2.54 cm)²
- 1² in² = 2.54² cm²
- 1 in² = 6.45 cm²
You can do this with any other conversion as well, so go wild with it!
Heres all of them including the finished one.. just in case
75x - 35 ≥ 77x + 63 + 4 Distributive property.
75x -35 ≥ 77x + 67 Combine like terms.
-2x - 35 ≥ 67 Subtraction property of equality.
-2x ≥ 102 Addition property of equality.
<span>x ≤ 51 Division property of equality.

5,120 because volume is area of base×height
I say it is 10% of 20$ and 30% of 10$ and 40% of 1$ and 20% of 5$
