Answer:
x = -13
Step-by-step explanation:
Distribute:
8 - 6x + 10x - 15 = 20 - 5x
Combine like terms:
4x - 7 = 20 - 5x
Isolate Variable
-x = 13
-1(-x) = -1(13)
x = -13
There is 2 figure here, a triangle and a parallelogram.
Area of parallelogram=base * height
A=9 * 5
A=45m²
Area of triangle=
![\frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20)
(base * height)
A=
![\frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20)
(9*8)
A=
![\frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20)
72
A=36m²
36+45=81m²
The area of this figure is 81m²
Answer:
Well to find 1/3 of something you have to multiply it by 1/3.
1/3 in decimal form is .33 repeating.
17.55 * .33 = 5.79
17.55 + 5.79 = $23.34
$23.34 is the total profit.
Answer:
-6 33/40
Step-by-step explanation:
![2\frac{5}{8} = 2.625\\-2\frac{3}{5} = 2.6\\\\2.625 *-2.6 = -6.825\\\\-6.825 = -6\frac{33}{40}](https://tex.z-dn.net/?f=2%5Cfrac%7B5%7D%7B8%7D%20%3D%202.625%5C%5C-2%5Cfrac%7B3%7D%7B5%7D%20%3D%202.6%5C%5C%5C%5C2.625%20%2A-2.6%20%3D%20-6.825%5C%5C%5C%5C-6.825%20%3D%20-6%5Cfrac%7B33%7D%7B40%7D)
Answer:
<em>3. x = 8</em>
<em>4. lines r and s</em>
Step-by-step explanation:
3.
The angles shown are same side interior angles, so they are supplementary. Their measures add to 180 deg.
5x + 10 + 130 = 180
5x + 140 = 180
5x = 40
x = 8
4.
Lines r and s are cut by a transversal, line l. Angles 3 and 6 are alternate interior angles. Lines r and s are parallel.
