(5x)/7 - x/14 = 9/7 solve for the unknown value this is a linear equation

Ahat [919]

Step-by-step explanation:

$\longmapsto \rm \dfrac{5x}{7} - \dfrac{x}{14} = \dfrac{9}{7} \\$

$\longmapsto \rm \dfrac{10x + x}{14} = \dfrac{9}{7} \\$

$\longmapsto \rm \dfrac{11x}{14} = \dfrac{9}{7} \\$

→ 11x(7) = 14(9)

→ 77x = 126

→ x = 126 ÷ 77

→ x = 1.63

*Find the area of the figure below. Use 3.14 for pi. Area= square inches

alex41 [277]

Answer:

100.26

Step-by-step explanation:

You would find the area of the semi circles on either side of the rectangle by plugging the diameter into the formula for the area of a circle. Then you would add that to the are of the rectangle.

This is what that would look like:

1. Divide 6 (the diameter) by 2 because $r=\frac{1}{2} d$

$r=\frac{1}{2} 6$

$r=3$

2. plug into the formula $A=\pi r^{2}$

$A=\pi 3^{2}$

3. square the 3

$A=\pi 9$

4. multiply 9 by 3.14 (pi)

$A=28.26$

This means the area of both the semi circles added together would equal 28.26

Then you would use the formula $A=lw$ to find the area of the rectangle

1. plug in the numbers given

$A= 12$ · $6$

2. solve

$A=72$

Then add the area of the semicircles to the area of the rectangle

$A=28.26+72$

to get the area of the entire figure:

$A=100.26$
