Let's check. 6 one-dollars = $6 15 five-dollars = $75 9 ten-dollars = $90 Add them all up to get $171, so that is correct. Add the number of one-dollar bills and the number of ten-dollar bills together. 6 + 9 = 15, which is the number of five-dollar bills, so that is correct as well. Add all the numbers of bills together, 6 + 9 + 15 = 15 + 15 = 30, so that is correct
$4.00 is my answer.
3x + 5(3) = 27
3x = 27 - 15
3x = 12
x = 12÷3
x = 4
Answer:
(±√3,±√+1)
Step-by-step explanation:
Answer:
100
Step-by-step explanation:
Hello! to calculate the number of tiles needed for the floor you need two things
1. number of tiles that fit across the width, this is achieved by dividing the total width by the width of each tile
Width=20ft=240in

2.number of tiles that fit in the logitude, this is achieved by dividing the total length by the length of each tile.
leght=30ft=360in

Finally, you multiply the number of tiles that fit in width by the number of tiles that fit in length.
N=10X10=100
First step: Find out the prime numbers that make up the radical, for example, 120 would be 2x2x2x5x3
Second step: If there is 2 of the same number that repeats just put that number in the front of the resulting radical
Third: Just multiply the remaining radicals together and put the number in front of it.
Now you have
