Answer:

Q1:

150 pages is the answer

2 hours= 60+60minutes

So 120/40 =3

Answer= 50×3= 150.

Q2:

Using Work=men×days we get

Work=20×20

Work=400

Now, work is same and number of days are to be calculated

400=25×days

days= 16

400 = 25 x 16

so it will take 16 days

Step-by-step explanation:

\begin{aligned} &y=2x +1 \\\\ &x-y=-3 \end{aligned} y=2x+1 x−y=−3 Is (2,5)(2,5)left parenthesis, 2, comma, 5, right

trapecia [35]

Answer:

Yes

Step-by-step explanation:

Given the system of equations

$\begin{aligned} &y=2x +1 \\\\ &x-y=-3 \end{aligned}$

We want to determine if (2,5) is a solution of the system.

We can do this by substitution of the given point into the equations and see if it holds.

Given (x,y)=(2,5), x=2, y=5

In the first equation

y=2x+1

5=2(2)+1

5=5

Therefore, the point (2,5) satisfies the first equation.

In the second equation

$x-y=2-5=-3$

Since our result (-3) is equal to the Right Hand Side, the point also satisfies the second equation.

Therefore, (2,5) is a solution of the system.
