Which equation represents the sentence? the sum of 14 and a number is 8 times the number a.14+n=8n b.14n=8+n c.14n+8=n d.14(n+8)=n

A. 14 + n = 8n

Step-by-step explanation:

The sum of 14 and a number (n) is 14 + n

8 times the number (n) is 8n

The sum of 14 and a number is 8 times the number would be represented as;

14 + n = 8n

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
