The resistance, R(in ohms), of a wire varies directly with the length, L(in cm), of the wire, and inversely with the cross sectional are, A(in cm^2). A 500cm piece of wire with a radius of 0.2cm has a resistance of 0.025 ohm. Find an equation that relates these variables.

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70

7000

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas
