Answer:
x = -52
y = -11
Step-by-step explanation:
Let 1st number = x
Let 2nd number = y
Hence:
x+y=-63
x-y=-41
y = x+41
(Apply Simultaneous Equations)
x+(x+41)=-63
2x+41=-63
2x=-63-41
2x=-104
x=-104/2
x=-52
Now:
y=-52+41
y=-11
I am going to use <em><u>DCVIMS.</u></em>
I would first distribute the parenthesis.
I would combine like terms.
I would put the variables on both sides.
I would do the inverse.
I would put my final answer.
Then substitute to check if it is correct! :D
6(2x−11)+15=3x+12
Simplify both sides of the equation.
6(2x−11)+15=3x+12
Simplify
6(2x−11)+15=3x+12
(6)(2x)+(6)(−11)+15=3x+12 (Distribute)
12x+−66+15=3x+12
(12x)+(−66+15)=3x+12 (Combine Like Terms)
12x+−51=3x+12
12x−51=3x+12
Subtract 3x from both sides.
12x−51−3x=3x+12−3x
9x−51=12
Add 51 to both sides.
9x−51+51=12+51
9x=63
Divide both sides by 9.
9x / 9 = 63 / 9
x=7
Plug in 7 to the orginal equation to make sure your answer is right!
Hope this helped! :D :D
There are
4 triangles that form. See the attached image.
4.35 x 3 x 10^(-3) = 13.05 x 10^(-3) = 1.305 x 10^(-2)
3/5 is it in simplest form.
Put 60 over 100 and then keep reducing until it can go any further.
