Answer:

$\boxed{\sf{x=24}}$

Step-by-step explanation:

GIVEN:

To find the missing number in the proportion, you have to isolate it the term of x from one side of the equation.

$\sf{\dfrac{8}{7}=\dfrac{x}{21} }$

First, thing you do is switch sides.

$\sf{\dfrac{x}{21}=\dfrac{8}{7} }$

Multiply by 21 from both sides.

$\Longrightarrow: \sf{\dfrac{21x}{21}=\dfrac{8*21}{7} }$

Solve.

Multiply the numbers from left to right.

Use the order of operations.

PEMDAS stands for:

Parentheses
Exponents
Multiply
Divide
Add
Subtract

$\Longrightarrow: \sf{\dfrac{8*21}{7}=\dfrac{168}{7}=24 }$

$\Longrightarrow: \boxed{\sf{x=24}}$

Therefore, the final answer is x=24.

I hope this helps. Let me know if you have any questions.

What is the perimeter and area of this figure? Round to the nearest whole number.

Tpy6a [65]

Answer:

Step-by-step explanation:

This figure is quarter of a circle.

=> Perimeter = π/2r + 2r

=> 5π + 10

=> 5(3.14) + 10

=> 15.7 + 10

=> 26 units

Area = πr²/4

=> 3.14 x 100 / 4

=> 25 x 3.14

=> 79 sq. units
