Step-by-step explanation:
<u><em>13x+1+7x+19</em></u>
<u><em>Combine Like Terms:</em></u>
<u><em>=13x+1+7x+19</em></u>
<u><em>=(13x+7x)+(1+19)</em></u>
<u><em>=20x+20</em></u>
y-2 = 38
parallel side have the same length in a parallelogram
add 2 to each side
y =40
17 = x+3
parallel side have the same length in a parallelogram
subtract 3 from each side
14 =x
opposite angles are equal in a parallelogram
124 = 2u
divide by 2
u = 63
angles on the same side add to 180
124+ v-3 =180
121+v=180
v = 59

Step-by-step explanation:
Answer:
It is more convenient to fill up in the United States.
Step-by-step explanation:
We convert a US gallon to liters:
1 Gallon equals 3.78541 liters.
Therefore, 1 US Gallon costs (3.78541) x (1.29) = 4.8831789 Canadian dollars.
Now we convert the price of a US gallon in Canadian territory to US dollars:
4.8831789 * 0.79 = 3.85771133 US dollars.
Conclusion: A gallon purchased in the United States costs 2.58 US dollars, while a gallon in Canada is equivalent to 3.85771133 US dollars. This way it is more convenient to fill up in the United States.
A rock climber's elevation above sea level changed −82 1/2 feet in 2 1/4 minutes as she descended.
so the the climber's average change in elevation per minute was:
x = -82 1/2 / 2 1/4x = (-165/2) / (9/4)x = (-165/2) x (4/9)x = -18 feet per minute is his change in elevation
