Answer:
x > 22
Step-by-step explanation:
<em>Hey there!</em>
Well to solve,
52 - 3x < -14
we need to single out x
52 - 3x < -14
-52 to both sides
-3x < -66
Divide both sides by -3
x > 22
The < changes to > because the variable number is a - being divided.

She drinks 4.27 grams on calcium in 14 days at one glass of milk containing 14 mg per day
So the equation looks like this : 15*3x=78
subtract 15 from both sides: -15 -15
then divide by 3 from both sides
to isolate the variable: 3x=63
3/3x=63/3
x=21 (your mystery number is 21)
Answer:
30 000 tiles
Step-by-step explanation:
Firstly convert the dimensions into metres
Then find the total surface area for one tile...in its....;
T.Surface area = 2(0.225 × 0.1) + 2(0.1 × 0.075) + 2(0.225 × 0.075)
Total surface area of one tile = 0.09375m^2
Then divide it into the surface area that the paint can be applied to....
2812.50 ÷ 0.09375 = 30 000 tiles
