since length multiplied by the width equals area,
so since the length is given, the width is needed
Answer:
x = 2, y = 9 or (2,9)
Step-by-step explanation:
Hello!
The first equation "y = 5x - 1" is telling us that y is equal to 5x - 1
We can plug in the first equation into the second like this:
2x + y = 13 (we know y so we can plug it in)
2x + (5x - 1) = 13
2x + 5x - 1 = 13
7x - 1 = 13
Now we add 1 to both sides
7x - 1 + 1 = 13 + 1
7x = 14
x = 2
Now we plug in x to find y:
y = 5x - 1
y = 5(2) - 1
y = 10 - 1
y = 9
Answer:
A = 28 in²
Step-by-step explanation:
Equation for the area of a parallelogram: <em>A = b * h</em>
Plug in: A = 7 in * 4 in
Solve: A = 28 in²
