Mathematics

Pavel [41]3 years ago

Answer:

(1, 5)

Step-by-step explanation:

The line of reflection is y = 1, which is a horizontal line with a y-intercept of 1. Each point must be the same distance away from this line, but on the other side of it. For example, X is 4 units away from y = 1, so X' must also be 4 units away, but on the other side. X' ends up at (1, 5).

Roger has $2, $1 and 50 cent pieces in the ratio of 5:4:2. If 30 of roger’s coins are 50 cent pieces, how many $2 coins and $1 c
rosijanka [135]

Answer:

Step-by-step explanation:

So the ratio is 5:4:2

there are 11 parts to this ratio (5+4+2)

the 5 is for the $2, the 4 is for the $1 and the 2 is for the 50 cents

he has 30 of the 50 cents

so you divide 30 by 2 to get one part of this ratio

1 part of this ratio is equal to 15 coins

multiply 15 by 5 to get the number of $2 coins: 75

multiply 15 by 4 to get the number of $1 coins: 60

add all of those parts together

30+60+75 = 165

If he uses a $1 coin to buy the sundae he will have 75 $2 coins and 59 $1 coins left

however, if he uses two 50 cents coins to buy the sundae he will have 75 $2 coins and 60 $1 coins left

Explain how you would solve 5x - 3 = 9. (there should be a minimum of 2<br> complete sentences). *
SpyIntel [72]
Haha, you first start off with adding 3 to both sides, cancelling the -3, and adding it to 9. you end up with 5x=12, in which you divide both sides by 5. you get 2 and 2/5 or 12/5! hope that helps :)
