A gardener can trim a square lawn of side 50 metres in 4 hours. At the same rate, how long will it take him to trim a square lawn of side 25 metres?

A)1 hour
B)2 hours
C)2 hours 30 minutes
D)3 hours

Answers

Answer:

2 hours

Step-by-step explanation:

50 metres / 4 hours = 25 metres / x hours

cross multiply both sides

50x = 25(4)

50x = 100

divide 50 both side

x = 100/50

x = 2 hours

2hours because 25 is half of 50 and two is half of four

Answers

Answer:

1) 18 quarters and 30 nickels2) 8 quarters and 12 nickels

Step-by-step explanation:

1) Let quarters be x and nickels be y.

Equations based on given, 48 coins, total of $6 = 600c:

x + y = 4825x + 5y = 600

Substitute y in the second equation, y = 48 - x

25x + 5(48 - x) = 60025x + 240 - 5x = 60020x = 360x = 18

Then value of y is:

y = 48 - 18 = 30

2) Similarly to problem 1.

x + y = 2025x + 5y = 260

Substitution: y= 20 - x

25x + 5(20 - x) = 26025x + 100 - 5x = 26020x = 160x = 8

Then finding y:

y = 20 - 8 = 12

Answers

I believe a reflection in the x-axis.

If you would to count the number of squares until you hit the y-axis, they would be the same, which means that you are looking at a reflection across the x-axis, for example F and L are 1 unit separated starting from the y-axis, and K and E are 8 units starting from the y-axis, meaning that is a reflection across the x-axis

slope =-5, y-intercept =-2

Answers

Answer:

y = -5x - 2

Step-by-step explanation:

y = mx + b

m = -5

b = -2

Step-by-step explanation:

I am not completely sure what your question is, but if you want to write an equation, you can just plug in the values for m and b to get y=-5x-2. If you wish to graph it, start at (0,-2) because that is your y-intercept. Next, move up 5 units and to the left 1 unit since the slope is negative. Now you have the point (-1,3). Connect the dots to get the graph.
