What is the missing numerator? blank over five plus eighteen over twenty equals thirty over twenty 8 5 3 2

Oliga [24]

Given:

$\dfrac{?}{5}+\dfrac{18}{20}=\dfrac{30}{20}$

To find:

The missing value.

Solution:

Let x be the missing value.

We have,

$\dfrac{x}{5}+\dfrac{18}{20}=\dfrac{30}{20}$

$\dfrac{x}{5}+\dfrac{9}{10}=\dfrac{3}{2}$

Subtract $\dfrac{9}{10}$ from both sides.

$\dfrac{x}{5}=\dfrac{3}{2}-\dfrac{9}{10}$

$\dfrac{x}{5}=\dfrac{15-9}{10}$

$\dfrac{x}{5}=\dfrac{6}{10}$

$\dfrac{x}{5}=\dfrac{3}{5}$

Multiplying both sides by 5, we get

$x=3$

So, the missing value is 3.

Therefore, the correct option is C.

The area of the figure. Use 3.14 for pie

balu736 [363]

Answer:

54.5 $ft^{2}$

Step-by-step explanation:

divide it to one rectangle and two different triangles.

Rectangles area: (8+3)*4 = 44 $ft^{2}$

triangle top: 4*3/2 = 6 $ft^{2}$

triangle bottom: 3*3/2= 4.5 $ft^{2}$

sum the all up: 44+6+4.5 = 54.5 $ft^{2}$

don't know how to do it with π though if that's obligatory
