Answer: there are eight bicycles and 7 tricycles.
Step-by-step explanation:
Let x represent the number of bicycles that are there.
Let y represent the number of tricycles that are there.
There are a total of 15 bicycles and tricycles. This means that
x + y = 15
A bicycle has 2 wheels and a tricycle has 3 wheels. There are 37 wheels all together if we count them up. This means that
2x + 3y = 37- - - - - - - - - - - - - 1
Substituting x = 15 - y into equation 1, it becomes
2(15 - y) + 3y = 37
30 - 2y + 3y = 37
- 2y + 3y = 37 - 30
y = 7
x = 15 - y = 15 - 7
x = 8
Answer:
3 with a remainder of 4 beads
Step-by-step explanation:
if you want to put 10 beads on each bracelet but you only have 34 beads you are going to do subtraction (this is division but subtraction is the easiest way to explain it) so you have 34 bead and that’s more than 10 so you can make a bracelet so subtract 10 from 34, so now you have 24 beads and one bracelet, now 24 is greater than 10 so subtract again, 24-10 which is 14 so now you have 14 beads and 2 bracelets and 14 is greater than 10 so we can make another, 14-10 is 4 so now you have 4 beads and 3 bracelets now 4 is less than 10 so you can’t make another (hope this helps)
