Question

In mathematical phrase

5. Length increased by ten meters

6. Cost of a shirt less 30% of its price

7. Twenty-five percent of the original price

8. Volume of water in the container increased by 5L

9. Twice the product of
`\pi`and the radius of a circle

10. Two kph faster than the rate of Xavier​

Answer 1

Answer: Sure, here are the mathematical expressions for each phrase:

Let L be the original length, then the new length is L + 10 meters.

Let p be the original price of the shirt, then the cost after the discount is p - 0.3p = 0.7p.

Let p be the original price of the item, then 25% of the original price is 0.25p.

Let V be the original volume of water in the container, then the new volume is V + 5L.

Let r be the radius of a circle, then twice the product of x and the radius is 2xr.

Let X be Xavier's rate, then the rate that is two kph faster than Xavier's rate is X + 2 kph.
