Sum of 54: X + Y = 54
Difference is 4: X - Y = 4

Solve for one variable first.

X = 4 + y (rewritten from second equation)

Now plug into the first equation for x

4 + y + y = 54
4 + 2y = 54 (subtract 4)
2y = 50 (divide by 2)
Y = 25

Now use Y to solve for X

X - 25 = 4 (add 25 on each side)
X = 29

HELP!!! <br><br> Which function shows a fabric with a price of $1.25 per square yard?
ohaa [14]

Answer:

y=1.25x

Step-by-step explanation:

Let us assume that,

x represents the number of sq. yards of fabric and

y represents price of the fabric.

As the unit price of the fabric i.e cost per sq. yard of fabric is $1.25, so for each number of sq. yard of fabric, the cost for that much of fabric will be multiple of 1.25 of that number.

i.e y=1.25x

Here, the rate of change is 1.25. So for each increase in x, the amount of increase in y is 1.25

The table along with the graph have been attached below.

Answer: 140

Step-by-step explanation: since 4 = 40 then 2 would also be 40 because they are the same angle (Keep in mind that a line is 180 degrees) 180-40=140! Good luck! :D
