Answer:
x = 1
Step-by-step explanation:
1/2x - 3/4 = 3/8 - 5/8x
The LCD is 8. Lets change every fraction to a denominator of 8.
4/8x - 6/8 = 3/8 - 5/8x
Now multiply both sides by 8.
4x - 6 = 3 - 5x
Add 5x to both sides. Add 6 to both sides.
9x = 9
Divide both sides by 9.
x = 1

Answer:
39.53 ft^2
Step-by-step explanation:
We can find the area of the rectangle
A = l*w
= 12*3 = 36
And the area of the semicircle
A = 1/2 pir^2
The diameter is 3, the radius is 3/2
=1/2 pi* (3/2)^2
= 1/2 *3.14 * 9/4
3.5325
Add the two areas together
36+3.532539.5325
Rounding to the nearest hundredth

Answer:
<h2>
y= -x -10</h2>
y=mx+b
plug in -6 for y and -4 for x and - for m
-6=-(-4)+b
solve for b
b=-10
set up equation
Answer:
-1/21
Step-by-step explanation:
2/3 + -5/7
Get a common denominator of 21
2/3 *7/7 = 14/21
-5/7*3/3 = -15/21
14/21 - 15/21 = -1/21
