PEMDAS 1-B by Dec. 8

• 20 + (2 x 7) - 50 = C

• 20 - (2 x 7) - 50 = C

• 50 - 20 + (2 x 7) = C

• 50 - 20 - (2 x 7) = C

• (3 + 16) - 6 = C

• (3 x 16) - 6 = C

• (16 x 3) + 6 = C

• (16 x 3) - 6 = C

• (16 + 16 + 16) - 6 = C

• T = (2 x 22) + (3 x 34)

• T = (3 x 22) + (2 x 34)

• T = (34 + 22) + (2 x 3)

• T = (2 + 3) x (34 + 22)

• G = (2 x 6) + 7 - 5

• G = (2 x 5) + 5 - 6

• G = (5 x 7) + 2 + 6

• G = (2 x 7) + 6 - 5

Read the question carefully:

Jordan has 5 boxes of dinner plates for a party. There are 30 dinner plates in each box. Jordan places 45 plates on one table and 55 plates on another table. He places the rest of the plates on the counter. The bar model can be used to find the number of plates Jordan placed on the counter.

Let P be the total number of plates Jordan has. C is the number of plates on the counter.

Which equation or expression gives the number of plates in the top row of the bar model?

• C = 5 x 30 - (45 + 55)

• P = 5 + 30

• 45 + 55

• P = 5 x 30

• C = 5 x 30 + (45 + 55)

Let P be the total number of plates Jordan has. C is the number of plates on the counter.

Which equation or expression solves the total number of dinner plates on the table?

• C = 5 x 30 - (45 + 55)

• P = 5 + 30

• 45 + 55

• P = 5 x 30

• C = 5 x 30 + (45 + 55)

Let P be the total number of plates Jordan has. C is the number of plates on the counter.

Which equation or expression gives the number of leftover plates (the question mark)?

• C = 5 x 30 - (45 + 55)

• P = 5 + 30

• 45 + 55

• P = 5 x 30

• C = 5 x 30 + (45 + 55)

Which represents "5 times as many as 52 is r"?

• 52 ÷ 5 = r

• r = 52 - 5

• 52 + 5 = r

• r = 52 x 5

Read the question carefully:

Mina has 5 boxes of salad plates for the party. Each of her boxes has 10 more plates than Jordan's boxes. Mina places a salad plate on top of each of Jordan's plates at both tables. Mina also places the rest of her plates on the counter.

How would the top row of Jordan's bar model change to suit Mina's boxes of plates?

• The numbers on the top row of the model would change from 30 to 40.

• The numbers on the bottom row of the model would be 10 more.

• The number of the question mark would be 50.

• The numbers on the top row of the model would change from 30 to 20.

Mina has 5 boxes of salad plates for the party. Each of her boxes has 10 more plates than Jordan's boxes. Mina places a salad plate on top of each of Jordan's plates at both tables. Mina also places the rest of her plates on the counter.

Which equation could find the total number of salad plates Mina has?

• T = 5 x 30

• T = 45 + 55

• T = 5 x 40

• T = (5 x 30) - (45 + 55)
