the formula m=1/5t can be used to determine how far in miles, you are from lightning when its thunder takes t seconds to reach your ears. if it takes 9 secs for the sound of thunder to reach you after you have seen the lightning how far away is the storm? will fan and medal
M = 1/5 t t = 9 So M =1/5 *9 = 1.8 miles So storm is 1.8 miles away
do you understand?
@pphalke

@Janu16
ohok
if i blow this then i cant pre test into the next module. how can a class be an hour and 50 mins not giving enough time for a test?
lol
4.2x-5.25=6.3-3.5x help @Janu16
simplfy this?
solve
ok solve for x tight?
yes
you have any chcoies?
Add 5.255.25 to both sides 4.2x=6.3−3.5x+5.25 4.2x=6.3−3.5x+5.25 2 Simplify 6.3−3.5x+5.256.3−3.5x+5.25 to −3.5x+11.55−3.5x+11.55 4.2x=−3.5x+11.55 4.2x=−3.5x+11.55 3 Add 3.5x3.5x to both sides 4.2x+3.5x=11.55 4.2x+3.5x=11.55 4 Simplify 4.2x+3.5x4.2x+3.5x to 7.7x7.7x 7.7x=11.55 7.7x=11.55 5 Divide both sides by 7.77.7 x=1.5
i got 1.5
