-7x+12-2x=23+13x
First take away 13x from the right side and put it on the left side adding taking it away from -7x
-7x(-13x)=-20x
-20x+12-2x=23
then add 2x to -20x
and move 12 to the other side, minus it off of 23
-18x=11
then divide -18x on both sides
then x=-11/18

Answer:
0.261 ohm
Step-by-step explanation:
If the radius increases by a factor of 0.7/0.4= 7/4, the square of this factor is (7/4)^2 = 49/16. The inverse of this square is 16/49, which is the factor by which the resistance changed.
The resistance of the larger wire is ...
(16/49)(0.80 ohm) ≈ 0.261 ohm
Answer:
135
Step-by-step explanation:
The equation is 135+90+x=360. x=360-(225)=135
Answer:1/2
Step-by-step explanation:
Zero is an integer but not a natural (counting) number.
Most square roots of integers are not rational numbers.
√2, √3, √5, √6, √7, and (pi) are real, irrational numbers.
