Answer:
x=7
Step-by-step explanation:
Since these angles are complementary, they will add up to 90 degrees, so you can set up the equation like so:
8x+5+3x+8=90
First, combine like terms:
(8x+3x)+(5+8)=90
11x+13=90
Then, subtract 13 from both sides:
11x+13(-13)=90(-13)
11x=77
Then divide both sides by 11:
11x(/11)=77(/11)
x=7
7 is your answer
hope this helps!
All u do is divide 3 into 74 but 3 cant get into 74 so u do the number the close in that 3 times 24 in that 72 but if u do 25 times 3 that 75 in the number cant be greater so then u know it 24 times 3 then u subtract 74 from 72 in get 2 as the remainder so u have 2 as the hold number in 3 as the nemonator in 24 as the denatorator
Alright, 1, 2, and 4 are correct but 3 is not.
The error you made could be hard to notice but it was made. So let's put the equation up, 6x-(2x-9)=-31. Your error occurred when you didn;t distribute the negative sign for (2x-9), if you woud have distributed it then the equation would then be simplified into 6x-2x+9=31. You then add like terms and get 4x+9=31, subtract 9 on both sides and you'll get 4x=22. Divide 4 on both sides to isolate the variable and you get x=5.5
Answer:
6x + 1
Step-by-step explanation:
1. (10x + 3) + (-4x -2) --> sum means to add.
2. Combine like terms --> 10x - 4x = 6x; 3 - 2 = 1.
3. 6x + 1
0.012 is the answer!
I hope this helps you out! :D
