Answer:
Step-by-step explanation:
x=7 would be horizontal and would be 7 units to the right of the origin, y= -2 would be vertical and 2 units down from the origin
Answer:
21%
Step-by-step explanation:
Since both 100 and 79 is the percentage, you need to find how much has decreased, so you have to subtract.
100-79 = 21
So, 21% was decreased.
Answer: The equations are
6x - 6y = 9
4x + 4y = 9
Step-by-step explanation:
Let x represent the speed of the row boat in still water.
Let y represent the speed of the current.
Dana can travel 9 miles in her rowboat in 6 hours against the current. This means that the total speed at which she travelled is
(x - y) miles per hour.
Distance = speed × time
Distance travelled against the current is expressed as
9 = 6(x - y)
6x - 6y = 9
With the current, it takes 4 hours to row the same distance. This means that the total speed at which she travelled is
(x + y) miles per hour.
Distance travelled with the current is expressed as
9 = 4(x + y)
4x + 4y = 9

Step-by-step explanation:
let the 1st number be x
given,
2nd number = 10 less than 1st number = x - 10
3rd number = 2 times the 1st number = 2x
their sum = 74
a/q,
x + x - 10 + 2x = 74
after solving the equation,
→ x + x - 10 + 2x = 74
→ 4x - 10 = 74
→ 4x = 74 + 10 = 84
→ 4x = 84
→ x = 84/4 = 21
therefore,
1st number = x = 21
2nd number = 10 - x = 21 - 10 = 11
3rd number = 2x = 2 × 21 = 42
