Leah ran 5/7 of a lap and Ryan ran 2/3 of a lap. Who ran farther and by how much?
Goryan [66]
Leah, she ran farther by 1/21

How you get the answer:

5/7
Multiply 7x3 to get the denominator and do the same to the numerator 5x3! Which is 15/21
To get 21 from 2/3 is to multiply 3x7 (denominator) and 2x7 (numerator) to get 14/21

15/21 > 14/21 so Leah ran farther by 1/21

josie cast a shadow of 6ft and she is 5 ft 6 in tall. A building cast a shadow of 18 ft at the same time that josie measured her
Debora [2.8K]
Josie's height = 5 ft 6 in. = 5 1/2 ft = 11/2 ft.
Josie's shadow = 6 ft.

Ratio of shadow to height = 6 / 11/2 = 12/11
So, It would be equal to ratio of building's shadow to building's height.

18/x = 12/11
x = 18*11 /12
x = 3*11 / 2
x = 16.5

In short, Your Answer would be 16.5 Feet

Hope this helps!

Y=2x y=7x + 15 substitution
sergejj [24]

y = 2x \\ y = 7x + 15

Substitute the given value of y into the equation y=7x+15

2x = 7x + 15

Move the variable to the left-hand side and change its sign

2x - 7x = 15

Collect like terms

- 5x = 15

Divide both sides of the equation by -5

x =  - 3

Substitute the given value of x into the equation y=2x

y = 2 \times ( - 3)

Solve the equation for y

y =  - 6

The possible solution of the system is the ordered pair (x,y)

(x,y) = ( - 3, - 6)
