Download photo-math on ur phone and take a picture of the equation. it should tell u the answer.
Area of 2 triangles = 2*(1/2)*6*8
= 48 square ft
Area of 1 rectangle = 10*5
= 50 square ft.
Area of 2nd rectangle = 5*6
= 30 square ft.
Area of 3rd rectangle = 5*8
= 40 square ft.
Surface area of figure = 40+30+50+48
= 168 square ft.
-5/3 divided by -11/5
Flip the second fraction so
-5/3 x -5/11
25/33
Answer:
See the first 3 problems solved below.
I added the next 3 problems.
Step-by-step explanation:
1.
2x + 4x = 180
6x = 180
x = 30
2x = 2(30) = 60
4x = 4(30) = 120
2.
3x + 6x = 180
9x = 180
x = 20
3x = 3(20) = 60
6x = 6(20) = 120
3.
8x + 10x = 180
18x = 180
x = 10
8x = 8(10) = 80
10x = 10(10) = 100
4.
7x + 8x = 180
15x = 180
x = 12
7x = 7(12) = 84
8x = 8(12) = 96
5.
2x + x = 180
3x = 180
x = 60
2x = 120
6.
2x + 2x = 180
4x = 180
x = 45
2x = 2(45) = 90
Answer:
In your equations, there is only one variable you're using: y. I do not know what you mean by 2 variables, but probably you copied the wrong equations.
......Anyways......
To solve it, you must know that the sum of all 3 angles of a triangle is 180°.
To set up the equation, add all three angle measures on one side of the equation, and then 180 on the other side. It should be like this:
(6y+1)+(4y-7)+(9y+3) = 180
Now that you're done with the set-up, I assume you know what to do next. We can't always do the work for you. ^_~
> Add up the measures of each angle.
> Isolate the equation with only variable on one side and only number on the other side.
> Substitute each variable y for each angle measure and solve it.
Hope this helps a lot. ^_^
