write two division equations for 15 times 2/5= 6

Answers

Two division equations:
6 divided by 2/5 = 15.
6 divided by 15 = 2/5.

Just to the opposite of multiplication.

The two division equations for 15 times 2/5 = 6 are 15÷(5/2) = 6 and

What is a fraction?

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

We know, N = DQ + R.

First type,

15×(2/5) = 6.

15÷(5/2) = 6.

Second type,

N = DQ + R.

15÷(5/2) = 6.

15 = (5/2)(6) + 0.

Answers

Answer:
LM = 33 units

Explanation:
From the drawing:
LM = NP
41 - 2x = 7x + 5
41 - 5 = 7x + 2x
36 = 9x
x = 9

This means that:
LM = 41 - 2x
LM = 41 - 2(4)

Write and solve an equation to answer the question. 83% of 20 is what number a

Answers

Of means multiply
(83/100) * 20
166 / 100
16.6 <<<<answer.

Final answer:

83% of 20 is 16.6.

Explanation:

To find 83% of 20, we need to understand that percent means per hundred.

So, to calculate 83% of a number, we can convert the percentage to a decimal by dividing by 100 and then multiply by the number.

In this case, the equation to find 83% of 20 is:

(83 ÷ 100) × 20 = x

Which simplifies to:

0.83 × 20 = x

Now, we do the multiplication:

0.83 × 20 = 16.6

Therefore, 83% of 20 is 16.6.

what the answer subtitution of x=6+y and ×-4y=21

Answers

x= 6 + y
x - 4y= 21

The first equation is already solved for x. Take the value of x (6 + y) and substitute it for the x value in the second equation.

x - 4y= 21
(6 + y) - 4y= 21
combine like terms
6 - 3y= 21
subtract 6 from both sides
-3y= 15
divide both sides by -3
y= -5

Substitute the -5 for y in the equation to solve for x

x - 4y= 21
x - 4(-5)= 21
x + 20= 21
subtract 20 from both sides
x= 1

CHECK:
x= 1
y= -5

x= 6 + y
1= 6 + (-5)
1= 1

ANSWER: x= 1 and y= -5

The area of the base of a rectangular prism is 18 cm2. The height of the prism is 9 1 2 cm. What is the volume of the prism?

Answers

The volume of the rectangular prism with a base area of 18 cm2 and height of 9 1/2 cm is calculated to be 171 cm3, using the formula Volume = area of base x height.

The volume of a rectangular prism is calculated by multiplying the area of the base by the height of the prism. In this case, the area of the base is given as 18 cm2, and the height is 9 1/2 cm, which can also be written as 9.5 cm for easier multiplication.

To find the volume, we use the formula: Volume = area of base * height. Substituting the known values, we get:

Volume = 18 cm2 * 9.5 cm

Volume = 171 cm3

Therefore, the volume of the rectangular prism is 171 cm3.

Frank averages 3 strikes for every 10 frames that he bowls. If he bowled 42 strikes in a season, how many frames did frank bowl?

A. 126 frames
B. 140 frames

Answers

For this case we can make the following rule of three:
3 strikes ---------> 10 frames
42 strikes -------> x
From here, we clear the value of x.
We have then:

We have,

Two natural numbers a and b.

a and b are prime numbers.

The greatest common divisor of a and b:

The prime numbers have 1 and the number itself as its factors.

So,
a x 1 = a

b x 1 = b

1 is the GCD of a and b.

The lowest common multiple of a and b:

a x b = ab

ab is the lowest common multiple of a and b.

Thus,

The greatest common divisor of a and b is 1.

The GCD of two different prime numbers is 1, and the LCM is the product of the two primes.

GCD(a,b) is the Greatest Common Divisor, which is the largest positive integer that divides both numbers without a remainder. For two different prime numbers a and b, their GCD will be 1 because there are no common factors other than 1. LCM(a,b) is the Least Common Multiple, which is the smallest multiple that is divisible by both numbers. For prime numbers a and b, their LCM will be the product of the two primes.
