Fiona purchased 400 m2 of plastic sheeting and needs to cut it into rectangles of area 500 cm2. This can be done with no waste.
hoa [83]

Answer:

  8000

Step-by-step explanation:

The number will be ...

  (400 m^2)/(500 cm^2) = 0.8 (m/cm)^2 = 0.8 ((100 cm)/(1 cm))^2

  = 0.8·100^2 = 8000

Fiona can cut 8000 rectangles from the plastic sheeting she bought.

What is the value of the digit 5 in the number 75
scZoUnD [109]
The value would be 5 itself because it is in the ones place. If it were in the tens place it would be 50, if it were in the hundreds place it would be 500, and so on. Hope this helps. Let me know if you need anything else or if I can clarify anything for you, and feel free to post more questions.

How do I turn 5 — 3(х+1) — 2y — 3х + 2 into an y=mx+b form​
7nadin3 [17]

Answer:

y = -3x + 2

Step-by-step explanation:

Ok so I assumed that you are setting this equal to 0 or there would be an equal sign in the equation.  So basically you just want to gather like terms on each side so the y's on the left and the x's on the right.  You then want to solve using algebra and you have your answer!  I will add a picture to show my steps.
