4. Is 250%, and 5. Is 500%

Explanation:
For #4, the coin is equal to $2 1/2, or $2.50. Since the question is asking the worth of each coin as a percentage of $1, $2.50 will be a percentage greater than 100%. $2.50 is 2.5x $1, so if $1 is seen as 100% in this problem, we can do 100 x 2.5. This is how you get the answer of 250%

You use the same method for question 5, except $5 is 5x $1, so we can do 100 x 5 to get 500%

There are 27 red or blue marbles in a bag. The number of red marbles is five less than three times the number of blue marbles. H
sveticcg [70]

The number of red marbles in the bag is 19 and the number of blue marbles is 8.

<u>Explanation:</u>

Let R be the number of red marbles

Let B be the number of blue marbles

According to the question,

R + B = 27 (Total number of marbles is 27 )                 -1

R = 3B - 5 (Number of red marbles is 5 less than 3 times the number of blue marbles )

Substitute the right half of the second equation for R in the first equation

3B - 5 + B = 27

Add 5 to each side and combine the Bs

4B = 32

Divide both sides by 4

B = 8

Use this value of B in the first equation

R + 8 = 27

R = 19

Therefore, number of red marbles in the bag is 19 and the number of blue marbles is 8.

puteri [66]

Answer:

y=3x-2

Step-by-step explanation:

your question didn't have any instructions so this might not be what you're looking for

set them equal to each other

-3x+4=3x-2

-3x-3x=-2-4

-6x=-6

x=1

plug in x=1

y=3(1)+4   =7

y=3(1)-2   =1

so, when x=1, y=1 in the expression y=3x-2
