Answer:
$24.50
Step-by-step explanation:
9.10/2=4.55
4.55+19.95=24.50
For these kinds of problems, focus on getting one unit, and then do the other one.
Since there are 60 seconds in a minute, 39 feet per minute=39/60 or 13/20 feet per second.
Since there are 3 feet in a yard, 13/20 feet per second =13/60 yards per second.
The answer is 13/60 yards per second.
Hope this helps!

Please let me know if you have any questions
So average=(total of scores)/(number of tests)
needs at least average of 70
at least is represented as greater than or equal to or the sign (<u>></u>)
70<u>></u>(total)/(number oftests)
since we have 3 tests, we have to have 3 scores so
70<u>></u>(x+y+z)/3
he scored 85 and 60
70<u>></u>(x+85+60)/3 (doesn't matter which to subsitute)
70<u>></u>(x+145)/3
multiply obht sides by 3
210<u>></u>x+145
subtract 145 from both sides
65<u>></u>x
he needs to get at leas 65 on his third test
