Answer:
x=−4 and y=1
Step-by-step explanation:
Rewrite equations:
y=−2x−7;−3x+4y=16
Step: Solvey=−2x−7for y:
y=−2x−7
Step: Substitute−2x−7foryin−3x+4y=16:
−3x+4y=16
−3x+4(−2x−7)=16
−11x−28=16(Simplify both sides of the equation)
−11x−28+28=16+28(Add 28 to both sides)
−11x=44
-11x/-11=44/-11
x=−4
Step: Substitute−4forxiny=−2x−7:
y=−2x−7
y=(−2)(−4)−7
y=1(Simplify both sides of the equation)
x=−4 and y=1

Step-by-step explanation:
<u><em>The complete question is</em></u>
Jessica has 84.5 yards of fabric to make curtains. She makes 6 identical curtains and has 19.7 of fabric remaining. How many yards of fabric does Jessica use per curtain?
Let
x-------> amount of yards of fabric that Jessica used per curtain
we know that
The length of 6 identical curtains plus the length of the fabric remaining, must be equal to the total yards of fabric'
so
The linear equation that represent this situation is
Solve for x
Answer:4/3 is what I got
Step-by-step explanation:
a = Lw
Lw = 1/2
w = (1/2)/L
L = 3/8
w = (1/2)/L
w = (1/2)/(3/8)
w = (1/2)*(8/3)
w = (1/1)*(4/3)
answer:w = 4/3 inch
