Answer:I think it's 3 7.75/20 hours

Step-by-step explanation:

Multiply 2/15 by 20 (2x20 and 15x20)

Then 13/20 by 15 (13x15 and 20x15)

Subtract (195/300 - 40/300)

And you get 155/300

Then divide by 20 because dividing by 15 gives you 10.333333

So divide 155/300 by 20 (155÷20 and 300÷20)

And you get 7.75/20

Finally subtract the 2 hours from 5 hours and get 3 hours

Your answer is 3 7.75 hours

Solve the system of equations algebraically.
lubasha [3.4K]

Answer:

Option (d) is correct.

(1, 0) is the solution of the given system of equation.

Step-by-step explanation:

Consider the given system of equation

4x - 2y = 4    ........(1)

6x - 4y = 6   ........(2)

We have to solve the system algebraically ,

We will solve it by elimination method,

Multiply equation (1) by 2, we get,

(1) ⇒ 8x - 4y = 8        ............(3)

Subtract equation (2) from (3) , we get,

8x - 4y - (6x - 4y) = 8 - 6

8x - 4y - 6x + 4y = 2

8x - 6x = 2

⇒ x = 1

Substitute x = 1 in (1) and solve for y , we get,

⇒ 4x - 2y = 4 ⇒ 4 (1) - 2y = 4 ⇒ 2y = 4 - 4  ⇒ 2y = 0 ⇒ y = 0

Thus,  (1, 0) is the solution of the given system of equation.

Option (d) is correct.

8/f = 56/105 what is f?
svetlana [45]
8/15 = 56/105

This may be solved using proportion.
a/b = c/d
ad = bc   where cross products are equal.

a = 8
b = f
c  = 56
d = 105

ad = bc
8*105 = f*56
840 = 56f
840/56 = 56f/56
f = 15

56 ÷ 7 = 8
105 ÷ 7 = 15
