A board 65 inches long is sawed into two pieces, so that one piece is 7 inches shorter than twice the length of the other piece

Pavel [41]

Answer:

The length of the two pieces are 41 in and 24 in

Step-by-step explanation:

Let

x -----> the length of one piece

y ----> the length of the other piece

we know that

$x+y=65$ -----> equation A

$x=2y-7$ -----> equation B

Solve the system of equations by substitution

Substitute equation B in equation A and solve for y

$(2y-7)+y=65\\ 3y=65+7\\ 3y=72\\ y=24\ in$

Find the value of x

$x=2(24)-7\\ x=48-7=41\ in$

therefore

The length of the two pieces are 41 in and 24 in

Please help because I'm getting confused, and please show step by step. :(

Westkost [7]

So lets just simplify them first
1 batch = 2 3/4 so...
11/4 cups

and you need to make 3 1/2 batch so..
7/2 batch

then you just multiply it...
11/4 x 7/2
=77/8
=9 5/8

so you will need 9 5/8 cups
