Translate to a system of equations:
omeli [17]

Answer:

m + n = 15

m - 3 = n

The numbers are 9 and 6

Step-by-step explanation:

From the question,

The sum of two numbers is fifteen; the first number is m and the second number is n. To translate to a system of equations, we can write that

m + n = 15 ..... (1)

Also, from the question,

One number is three less than the other,

Also, to translate to a system of equations, we can write that

m - 3 = n ...... (2)

If desired, we can determine m and n

From equation (1)

m + n = 15

Then,

m = 15 - n ...... (3)

Put the value of m in equation (3) into equation (2)

m - 3 = n

Then

15 - n - 3 = n

15 - 3 = n + n

12 = 2n

n = 12/2

∴ n = 6

For m, put the value of n into equation 3

m = 15 - n

m = 15 - 6

m = 9

∴ m = 9 and n = 6

Hence, the numbers are 9 and 6

You're at a clothing store that dyes your clothes while you wait. You get to pick from 4 pieces of clothing
Zielflug [23.3K]

1 / 12 is the probability that you'll end up with an  orange hat.

<u>Step-by-step explanation:</u>

Given that,

  • There are 4 piece of clothing ⇒ shirt, pants, socks, or hat
  • There are 3 possible colors ⇒ purple, blue, or orange

<u>To find the total number of outcome :</u>

Total outcomes ⇒ (number of clothes) × (number of colors)

⇒ 4 × 3 = 12

 Therefore, there will be 12 different possibilities.

<u>The 12 different outcomes are :</u>

⇒ Purple shirt, blue shirt, orange shirt

⇒ Purple pants, blue pants, orange pants

⇒ Purple socks, blue socks, orange socks

⇒ Purple hat, blue hat, and orange hat.

Now, the probability that you'll end up with an  orange hat if you choose on random of 12 possibilities ⇒ No.of orange hats / Total no.of outcomes.

∴ P(orange hat) = 1 / 12
