Answer:
z=30
Step-by-step explanation:
40-10=30
10+10+?=30
30-10-10=10
I'm sorry cuz I don't know how to explain it
Recall that the direction of a vector can be seen from its slope, namely b/a.
let's take a peek at a couple of vectors, and multiply them by a scalar of 2.
hmmm say < 3 , 7 > , it has a slope of 7/3, now if we use a scalar of 2
2<3,7> => < 6 , 14 >, now, the slope of that is 14/6 which simplifies to, yeap, you guessed it, to 7/3, no change in the slope.
and say hmmmm < 11 , -2 >, slope of -2/11, let's multiply it by 2
2<11,-2> => <22 , -4 >, slope is -4/22 which simplifies to -2/11.
so, the vector's magnitude gets blown up, but the slope remains the same.

Answer:
$4.70 + $4.75m = $18.95 which is 3 miles in total.
Step-by-step explanation:
First make the numbers without the variables on one side.
4.75m = 18.95-4.70
Then subtract.
4.75m = 14.25
Finally divide the two numbers.
14.25 ÷ 4.75 = 3 miles
Answer: m = 3 or 3 miles
