Your answer will be c.
because if 10 is y and 20 is x and equation is : y = 0.50x
= 0.50 X 20
= 10
which means <span>brad will get $10 for selling 20 cups of lemonade.

Answer:
Get rid of distractions that makes you procrastinate.
Step-by-step explanation:
Focus doing your practices. To focus, you need to get rid of any distractions that make you procrastinate.
As an example, if it's your phone/social media. Try to make it silent/put it away from you when you're going to do your practices. (recommended to give to parents or put in other room until you finish your works)
This is just my suggestion. It works for some people.
Let's try to do this with a little guess and check.
We'll use numbers easily divided by 3 for the older brother's age.
If the older brother is 30, the younger brother is 16. (30 + 16 = 46)
Now, we check that with the 10 + 1/3 the older brother's age.
30 ÷ 3 = 10
10 + 10 = 20
20 > 16
That one doesn't work.
Let's try 24 for the older brother's age.
That means the younger brother would be 22, because 24 + 22 = 46.
24 ÷ 3 = 8
8 + 10 = 18
18 < 22
That one doesn't work, either.
We'll try one more. If the older brother is 27, the younger brother would be 19. (27 + 19 = 46)
27 ÷ 3 = 9
9 + 10 = 19
19 = 19
This one fits all the requirements of the problem.
That means that the answer to the question of "how old is the younger brother?" is
The younger brother is 19 years old.

Step-by-step explanation:
Answer: There are 100 three-bedroom units .
There are 101 four-bedroom units.
Step-by-step explanation:
Let x denotes the number of condominiums having three bedrooms and y denotes the condominiums with four-bedrooms.
Then according to the given description, we have
Multiply 3 on both sides of eqn (1), we get
Subtract equation (3) from (2), we gte
Put y= 101 in (1), we get
Hence, there are 100 three-bedroom units and 101 four-bedroom units.
