Mary has 12 marbles 3/12 of the marbles are yellow and 2/12 of the marbles are blue.The rest of the marbles are green.How many marbles are green?

Answers

3 yellow marbles + 2 blue marbles + x green marbles = 12 marbles
x green marbles = 12 marbles - 5 marbles
x green marbles = 7 green marbles
Of you take 12/12 (total number of marbles) minus 3/12 (amount of yellow marbles out of total) that leaves 9/12 and if you subtract 2/12 (amount of blue marbles from total) from that it leaves you with 7/12 (the amount of green marbles from the total.
Yellow=3
Blue=2
Green=7
Total=12

An engineer scale model shows a building that is 3 inches tall. If the scale is 1 inch = 600 feet, how tall is the actual building in feet ?

Answers

The actual height of building is 1800 feet.

Step-by-step explanation:

Given,

Height of building in model = 3 inches

Scale used by engineer;

1 inch = 600 feet

Therefore;

Actual height of building = Height in model * Scale used

Actual height of building = 3 * 600

Actual height of building = 1800 feet

The actual height of building is 1800 feet.

Answers

Answer:

Step-by-step explanation:

If m = 4, z = 9 and r = 1/6

1. 3 + m = 3 + 4 = 7

2. z - m = 9 - 4 = 5

3. 12r = 12 × 1/6 = 2

4. 60r - 4 = 60(1/6) - 4 = 10-4 = 6

5. 4m - 2 = 4(4) - 2 = 16-2 = 14
