I did x - 10 =290
+10 +10
-------------
x = 300 so they took $1.00 a day
752/12 = 62.66 and since she can't sell a portion of a 12 pack, she sold 62 whole packages and had 2/3 of one remaining, 2/3 of 12 is 8 remaining.
<u><em>Answers:</em></u>
a.
miles/day
b. 14 miles
<u><em>Explanation:</em></u>
<u>Part a:</u>
We are given that they paddled a total distance of 14 miles for 3 days. To get the distance paddled each day, we will divide the total paddled distance by the number of days
<u>This is done as follows:</u>
Distance paddled each day =
miles/day
<u>Part b:</u>
<u>Now, we are given that:</u>
<u>i. They went half their daily distance:</u>
Daily distance =
miles/day
<u>ii. They extended the trip twice as many days</u>
Number of days = 2 × 3 = 6 days
The total distance paddled will be equivalent to the product of the distance paddled each day and the total number of days
<u>This means that:</u>
Total distance =
miles
Hope this helps :)
Here is the answer below:
I won't write out a formal proof; here's an outline.
H+X=180. definition of supplementary
H+F=180 crossing lines
X=F supplements of the same angle are equal, or just algebra
l || n When the alternate angles of a transverse line between two lines are congruent, the lines are parallel
