Answer:
10a+b+9c
Step-by-step explanation:
first you have to join the like terms then you add them then you write the answer, I hope you understood
9c+5a+5a+b
9c+10a+b
10a+b+9c
Ok, to solve an algebraic equation we need to get the unknown by itself on one side of the equals sign. To do that, basically we just have to cancel everything else out... but whatever we do to cancel out what we don't want, we also have to do on the other side of the equals sign...
3x + 1/10 = x - 1/7
Let's start by getting the x on the right over to the left side. To cancel it from the right side we have to subtract it (x-x = 0). Don't forget to subtract it on the left also.
3x -x + 1/10 = x - x - 1/7
Now combine like terms
2x + 1/10 = -1/7
Now let's bring the 1/10 over to the right of the equals sign to get x by itself by subtracting it.
2x + 1/10 - 1/10 = -1/7 - 1/10
Combine like terms
2x = -1/7 - 1/10
Let's get a common denominator so we can combine the fractions
2x = -10/70 - 7/70
2x = -17/70
Now divide both sides by 2 to finish getting x by itself. To divide fractions, multiply the reciprocal.
x = -17/70 x 1/2
x = -17/140
Answer:
x = 4
y = 6
z = 8
Step-by-step explanation:
keep in mind I'm not doing that well with geometry so this might all be wrong lol
x is part of a 30 60 90 triangle.
so x is 4
next, this is a right angle triangle so you can follow the a^2 + b^2 = c^2 formula.
4 + 6 = 10
10^2 = 100
100 = a^2 + b^2
y = 6 and z = 8 bc 36 + 64 = 100
