Answer:
It is in the ones place and the value is 4
Step-by-step explanation:
In order to solve you must find the value of the blank angle.
Here is your first equation.
126 + x = 180
Subtract 126 from both sides.
x = 54
So now add up all the angles.
x + (2x + 6) + 54 = 180
Combine like terms.
3x + 60 = 180
Subtract 60 from both sides.
3x = 120
Divide.
x = 40
Now check your answer.
40 + 2(40) + 6 + 54 = 180
40 + 80 + 6 + 54 = 180
120 + 60 = 180
180 = 180
There is a solution. The answer is 40.
I hope this helps love! :)
Supplementary angle = 180 degrees
angle 1 = x
angle 2 = 3x (three times the supplementary)
3x + x = 180
4x = 180
x = 45 degrees
angle 1 = 45 degrees
angle 2 = 135 degrees
Well from what I know *I'm a 7th grader* this is a Unit rate problem so to find the unit rate we do 8/5 which is equal to 1.6 paintings per hour *used a calculator for this lol*
Answer:
Step-by-step explanation:
5 x + 10 y = 15 (1)
10 x + 3 y = 13
We want to use the linear combination method and addition to eliminate the x-terms, so we want in the equation (1), there will be the term -10x. Then, we have to multiple both side of (1) by -2.
And we have
-10 x - 20 y = - 30
10 x + 3 y = 13
------------------- (add)
0 - 17y = -17
or y = 1 and x = 1
