Answer:
The system will be:
x - y = 12
3x + 5y = 100
Step-by-step explanation:
Let The number of three-point questions ⇒ x
And the number of five-point questions ⇒ y
The giving a test has 12 more three-point questions than five-point questions.
So, x - y = 12
The test is worth 100 points.
So, 3x + 5y = 100
So. the system which represents this information is:
x - y = 12
3x + 5y = 100
And the solution of the system is x = 20 and y = 8
The number of three-point questions ⇒ x = 20 questions.
The number of five-point questions ⇒ y = 8 questions.
Answer:
7/15 is 12 years old from Wisconsin
Step-by-step explanation:
3/5 from 7/9 were 12 years old, which means
(3/5) · (7/9) = (3 · 7)/(5 · 9) =>
When we divide the numerator and the denominator of the fraction with number 3 we get
=> 7/15
God with you!!!
The volume of cylinder formula is πr²h.
V = π(12)²(9)
V = 1296π³
So the correct answer is 1296π³
Gasoline is a homogeneous mixture.
The correct answer is b. gasoline.
