Step-by-step explanation: Given in the question that Lana completed a 10-mile race in 90 minutes by running and walking both. She usually runs at a pace of 8.5 minutes per mile and walks at a pace of 12 minutes per mile. We need to find the number of minutes for which she ran and walk throughout the race.
Let, Lana runs for 'x' miles and walks for 'y' miles. Then, we have
Multiplying the first equation by 8.5 and subtracting from the second equation, we have
Therefore,
Thus, time for which Lana ran is
And, the time for which Lana walks is
Thus, the answers are
Answer:
where is the statement........
The scale is determined by dividing the respective measures of the two paintings.
Original painting mural scale factor
3 15 original / mural = 3 / 15 = 1 / 5
2 10 original / mural = 2 / 10 = 1 / 5
As you see the scale to comparing the original to the mural es 1 feet : 5 feet.
It means that the measures of the original painting must be multiplied by 5 to obtain the measures of the mural.
Answer:26 first class stamps and 28 additional.
Step-by-step explanation:
From information given,we can formulate the following equation: 47n +25(54-n ) = 1922
Now we solve for n .
47 + 1350+ 25n =1922
47n -25n =1922- 1350
22n=572
n= 26 .
Therefore 26 first class stamps and 28 additional. 54 total
G is Grant
e is Ethan
g=17
e= 17-4 = 13
17+13= 30 fishes
