36÷0.45=80
There are 80 beads altogether

Breaking down the numbers shows that if 45% is 36 beads, then 5% is 4 beads (divide by 9). Then multiply 5% by 20 (to get 100%) and 4 beads by 20 (distributive property) to have 80 beads.

write an expression that describes the number of points scored on touchdowns t and points after touchdowns p by one team in a ga
Len [333]
A touchdown is scored 6 points for each touchdown and the points made after a touchdown is scored 2 points each. We are given the following variables:

t = number of touchdowns
p = number of points after a touchdown

Total score = 6t + 2p

Where 6 times t is the total score given by the number of touchdowns multiplied by 6 points, the same goes for the expression 2p.
