Answer:
x = 10
Step-by-step explanation:
Given
14x - 7 = 133 ( add 7 to both sides )
14x = 140 ( divide both sides by 14 )
x = 10
This is a typical algebra problem pretending to be geometry. The two indicated angles are supplementary, adding to 180 degrees, precisely when the lines are parallel.
It's not really indicated, but the 8 and the 2 are in units of degrees.
6x + 8 + 4x + 2 = 180
10x = 170
x = 17 degrees
Step-by-step explanation:
1) -5n+10n
= 5n
2) -x-9+2x-10
= 2x-x-9-10
= x-19
3) -5(x-10)-x
= -5x+50-x
= -6x+50
4) 9-5(1-7x)
= 9-5+35x
= 35x+4
5) y^2-x
= 3^2-2
= 9-2
= 7
Do the remain questions by yourself, you can do it!
Answer:
Make sure the mode is on degree and not radian! Common mistake
Answer:
Simplify the problems first
Step-by-step explanation:
Before you can convert it to scientific notation, you should simplify it first.
#1 for example:
Use PEMDAS to solve the equation:
So, now we have a super big number. To write it in scientific notation, put a decimal place in the number before the zeroes start. It would be 
since there are 11 places after the decimal.
