Answer:
x=40
Step-by-step explanation:
80°+(2x+20)°= 180°... (co-interior angles are supplementary)
2x=180 - 80 - 20
2x=80
(divide both sides by the coefficient of x which is 2)
x=80÷2
x=40
Check:
(2x+20) must be equal to 100
Let x=40
Therefore :
2X40+20
=100
Answer:
So, I'm assuming false
Step-by-step explanation:
1. Determine the number by which to increase the smaller exponent by so it is equal to the larger exponent.
2. Increase the smaller exponent by this number and move the decimal point of the number with the smaller exponent to the left the same number of places. .
3. Add or subtract the new coefficients.
Answer:
Step-by-step explanation:
I think this question is about simplifying,so:
For simplify --- you must sum same things together.
2x+3x+5+8+8c+4c+7+6+5+0+9=
(2x+3x)+(8c+4c)+(5+8+7+6+5+0+9)=
5x+12c+41
