X+2y=5
x = -2y+5

-2(-2y+5) - y = -4
4y - 10 -y = -4
3y - 10 = -4
3y = 6
y = 2

x + 2(2) = 5
x + 4 = 5
x= 1

Therefore, the coordinates are (1,2).

Work out the volume of this prism.
aniked [119]

Answer:

Volume = 175 cm³

Step-by-step explanation:

We can picture this image as a whole rectangular prism, with a part that has been cut out of it.

Step 1: Volume of original prism

We are going to solve the volume of the original prism, with the dimensions of 9, 7, and 5

  • V = 9 * 7 * 5
  • V = 315

Step 2: Volume of part cut out

We are solving the volume of that part that has been cut out ( missing space)

  • V = 5 * (9-2) * (7-3)
  • V = 5 * 7 * 4
  • V = 140

Step 3: Total Volume

Now we just subtract the cutout part from the original volume

  • 315 - 140
  • V = 175

Volume = 175 cm³

Note, we could have also found the volume by splitting this shape into two prisms with dimensions (9 * 3 * 5) and (4 * 5 * 2). This way would also get us:

  • V = (9 * 3 * 5) + (4 * 5 * 2)
  • V = 135 + 40
  • V = 175

What are some equivalent fractions for 1/20
Talja [164]
Some equivalent fractions of 1/20 are:
<span>1/20 = 2/40 = 3/60 = 4/80 = 5/100 = 6/120 = 7/140 = 8/160 = 9/180 = 10/200 = 11/220 = 12/240 = 13/260 = 14/280 = 15/300 = 16/320 = 17/340 = 18/360 = 19/380 = 20/400</span>
