Jaclyn gets a hit 40% of the time while playing softball. She is going to use colored tiles to simulate her chances of getting a
azamat

Answer:

18 red tiles

Step-by-step explanation:

One way to look at this problem would be to take the number of tiles that Jaclyn used to get a possibility of 40% hits.

Jaclyn put 12 green tiles, this represents the 40% of the hits that she could get.

Now we know that 12 = 40%

We need to find how many red tiles she should put to still keep the 12 green tiles as 40%. We can also assume that 12 red tiles would be another 40%.

So we have 12 red tiles currently.

Now we still have another 20% left.

Since 12 red tiles = 40%, we can assume that:

6 red tiles = 20% of the total.

So if we add both the 40% red tiles to the 20% red tiles we get:

12 + 6 = 18 red tiles.

So Jaclyn will have to put 18 red tiles and 12 green tiles to simulate her chances of getting a hit.

spin [16.1K]

Answer:

(1,3)

y= 3

x= 1

Step-by-step explanation:

7x+y=10

3x-2y= -3

solve the equation

y=10-7x

3x-2y= -3

substitute the value of y into an equation

3x-2(10-7x)= -3

distribute

3x-20-14x= -3

add 14x from both sides

17x-20= -3

add 20 from both sides

17x=17

divide both sides by 17

x=1

substitute the value of x into an equation

y=10-7•1

multiply 7 to 1

y=10-7

subtract

y=3
