Squares have all equal sides so 10x4=40 40 ft is the answer
Answer:
Width is 2 and Length is 6
Step-by-step explanation:
- As the data is given, the area of a playground is 12 square yards.
- The length of the playground is 3 times longer than its width.
- Let width is x, length is 3 times therefore, length = 3x
As we know the formula for area,
So by putting values in this formula,
=> 3x2 = 12
=> x2 = 12/3,
=> x2 = 4 ,
by taking square root we get x= 2,
- the width is 2 and length is 3 times hence, length is 3(2) = 6.
Here, we need to set up a proportion.
4.5 miles in 15 minutes.
In 75 minutes, how much miles can he ride?
4.5/15 = x/75
Cross multiply
4.5 * 75 = 337.5
15*x = 15x
15x = 337.5
15x/15 = 337.5/15
x= 22.5
Final answer:- Tommy can ride 22.5 miles in 75 minutes.
3x - y = 0 . . . (1)
5x + 2y = 22 . . . (2)
From (1), y = 3x . . . (3)
Putting (3) into (2) gives:
5x + 2(3x) = 22
5x + 6x = 22
11x = 22
x = 2
From (3), y = 3(11) = 33
x = 11, y = 33.
D because divide both sides by nine
