Answer:$2343.28 for the turkey
Step-by-step explanation:
1,723lbs*$1.36=$2,342.28
Notice that the terms in parentheses on both sides of the equation are added to 4.
(3x + 4) + 4 = (5x - 4) + 4
So we can set the equation as.
3x + 4 = 5x - 4
Subtract 3x on both sides of equation.
4 = 2x - 4
Add 4 on both sides of equation.
8 = 2x
Divide both sides of equation by 2.
4 = x
4 is the only value that satisfies the statement.
He should tell Bill that depending on which side he wants the width or the length on, he should attach another board about 8 feet long to the 7 foot board since that is the length and he shouldnt attach anymore wood to the second board.
I first found x using the second equation :
-2x+4y=15
-2x = -4y+15
x =2y-7.5
Then, I substituted this value into the OTHER equation :
2x+5y=7
2(2y-7.5)+5y=7
4y-15+5y=7
9y=22
y=2.444
So you have you y value. Now, input this value into any one of the other equations (it doesn't matter which) to find x.
-2x+4y=15
-2x+4(2.444)=15
-2x+9.776=15
-2x=5.224
x=-2.612.
So the solution for this system of functions is (-2.612, 2.444).
