Answer:

A. x=5,y=6

Step-by-step explanation:

Add y to both sides of the equation.

x=−1+y

x−3y=−13

Replace all occurrences of x with −1+y in each equation.

−1−2y=−13

x=−1+y

Solve for y in the first equation.

y=6

x=−1+y

Replace all occurrences of y with 6 in each equation.

x=5

y=6

The solution to the system is the complete set of ordered pairs that are valid solutions.

(5,6)

The result can be shown in multiple forms. Equation Form: x=5,y=6

What is the approximate volume of one refraction cup? What’s its formula ?
Marizza181 [45]

Answer:

Volume = 0.1696 L

The formula is Area of base of refraction cup × Depth of the refraction cup

Step-by-step explanation:

The dimensions of a refraction cup are;

Diameter = 120 mm

Depth = 30 mm

Therefore, volume of the refraction cup = Area of base × Depth

Volume of the refraction cup = (π×120²/4)/2 × 30 = 169646.003 mm³

1 L = 1000000 mm³

Therefore, 169646.003 mm³ = 169646.003/1000000 m³ = 0.1696 L

The formula is Area of base of refraction cup × Depth of the refraction cup.

How do you calculate the percentage of a number?
faltersainse [42]
<h2>Answer:</h2>

Percentage is related to 100 and tells us how much we have of a quantity compared to another one. Suppose you have 100 cars and want to know how much cars are in red color. If 70 cars are red, then 70 percent of the cars are red. In general, we can find the percentage of a number following the steps:

For this example, let's take number 200 and the percentage 20%:

STEP 1: Multiply the number by the percentage:

200 x 20 = 4000

STEP 2: Now divide the number by 100:

400/100 = 40

STEP 3: If necessary., round to the desired precision.
