Answer:-55
Step-by-step explanation:-300 + 245 = -55
Easy
y=2x-7
sub 2x-7 for every y you se inother equation
x+2(2x-7)=1
x+4x-14=1
5x-14=1
add 14 both sides
5x=15
divide 5
x=3
sub back
y=2x-7
y=2(3)-7
y=6-7
y=-1
(3,-1) is solution

Answer:
1/6 squared feet or 0.17 squared feet
Step-by-step explanation:
Since it's a paper, we assume it is a rectangle.
Use the formula for area of a rectangle. A= lw
l is the length and w is the width.
The width is 2/3 feet and the length is 1/4 feet.
Substitute w = 2/3 and l=1/4 into the equation for area of a rectangle.
A = lw
A = (1/4)(2/3) Multiply both numerators, then both denominators
A = 2/12 Simplify. Top and bottom are divisible by 2
A = 1/6
A ≈ 0.17 Rounded to two decimal places
When you multiply two numbers with units, the answer's unit becomes the squared unit.
Therefore the area of her paper is 1/6 squared feet, or 0.17 squared feet.
