X - 15 + 30 - 12 = 18;
Then x - 15 + 18 = 18;
x + 3 = 18;
x = $15 ( money has Ming-Li to begin with ).

X = original amount

x - 15 + 30 - 12 = 18
x + 30 - 27 = 18
x + 3 = 18
x = 18 - 3
x = 15 <== she began with 15

What would the area of an actual pool be in the scale from the drawing is 3:1000
elena55 [62]

Answer:

If this is the complete question them the answer is 1250 m²

Step-by-step explanation:

the pool in the drawing is 15x7.5 and the scale is 3/1000 so if the size in the drawing  is 3 then the actual is 1000.

x=15*1000/3=5000cm which would be 50m

x=7.5*1000/3=2500cm which is 25m

the actual area of the pool is 50*25=1250 m²

Inessa [10]
You would add 4.40 to 55.50 to get 59.90. because the sales tax is 8% which is 0.08 cents and multiply that by 55 to get 4.40

11. Use your ruler to measure in centimetres the lengths of the lines marked P, Q<br> and R.
miv72 [106K]

Unfortunately we are unable to do this question since the question would have to be in the correct scale (meaning we need the original copy not a camera version). This question must be done by you. Just use a ruler and measure the lines

How do you solve 5/6 ×20
Alex73 [517]
Ok so remember that if you had
1/2 times 3/4 that equals (1 ties 3)/(2 times 4)
just mutply top number with top number and bottom number with bottom number so

remember that 20=20/1 so
5/6 times 20/1=
5 times 20=100
6 times 1=6

5/6 times 20/1=100/6 (can be simplified to 50/3 or 16 and 2/3)
