IrinaVladis [17]

Answer:

98 x 3 = 294 or 3 x 98 = 294

Step-by-step explanation:

Since 294 divided by 3 is 98, that means 294 is 3 times 98. So, we can say:

3 x 98 = 294

We can also say that 98 x 3 = 294 since it doesn't matter in which order you multiply.

Find the value of y if the value of x is 2 for each equation and match it with the appropriate result.
Xelga [282]

9514 1404 393

Answer:

  3, 0, 2, -2

Step-by-step explanation:

Put x=2 into each equation and solve for y.

<u>2 + y = 5</u>

  y = 5 -2

  y = 3

<u>3x +2y = 6</u>

  3·2 +2y = 6

  2y = 6 -6 = 0

  y = 0

<u>2x +y = 6</u>

  2·2 +y = 6

  y = 6 -4

  y = 2

<u>5x +3y = 4</u>

  5·2 +3y = 4

  3y = 4 -10 = -6

  y = -2
