X = smaller number
y = bigger number

y = 3x

x+y = 20
x+3x = 20
4x = 20
x = 5

The smaller number is 5.

Ima houseseller earns a 3% commision for selling a house. if he sells a house for $120000, what is his commision
Masja [62]

Commission is earning a certain percentage of the total sold price.

To figure this out we need to find what is 3% of $120,000

We can do this by multiplying 3% and $120,000

First let's change 3% into a decimal.

3% = 0.03

Now lets multiply.

0.03 x $120,000 = $3,600

So this person earned $3,600 in commission.

Good Luck! :)

The sum of Sasha’s and Natalie’s ages is 31. Twice Natalie’s age is 11 years more than Sasha’s age. Find each of their ages
ZanzabumX [31]

Answer:

Natalie's age is 14

Sasha's age is 17

Step-by-step explanation:

Let

Sasha's age be "s", and

Natalie's age be "n"

<u>Sum of Sasha and Natalie is 31:</u>

s + n = 31

<u>Twice Natalie is 11 more than Sasha:</u>

2n = s + 11

We ca solve this equation for s first:

s = 2n - 11

We put this into first equation and solve for n first:

s + n = 31

2n - 11 + n = 31

3n = 31 + 11

3n = 42

n = 42/3 = 14

Natalie's age is 14

Also, s = 2n - 11

s = 2(14) - 11

s = 28 - 11

s = 17

Sasha's age is 17
