Step-by-step explanation:
hope this helps. :)
4. You remove the brackets
Remember:
-a × -b = positive ab / +ab
a × b = positive ab / +ab
-a × b = negative ab/ -ab
a × -b = negative ab / -ab
Where ab is the product of the two numbers & - or + are the signs.
a) 5(2x+3y) -4(3x-5y)
= 10x + 15y -12x + 20y
= 10x - 12x + 15y + 20y
= -2x + 35y
= 35y - 2x [I've been told that most people prefer the positive number in front rather than the negative number]
b) x- 2(x+ 3y) -(2x+3y) -4(x+y)b
= x - 2x - 6y - 2x - 3y - 4x - 4y
= x - 2x - 2x - 4x - 6y - 3y - 4y
= -7x - 13y
c) 3(a + 2b -2) -2(2a - 5b - 1)
= 3a + 6b - 6 -4a + 10b + 2
= 3a - 4a + 6b + 10b - 6 +2
= - a + 16b - 4
= 16b - a - 4
Answer:
It is 0.
Step-by-step explanation:
The question is asking you what number represents sea level, not how higher the plane is from the airport. Sea level is represented by 0.
Answer
0.27
Step-by-step explanation:
3 divided by 11
= 0.27
this is it I believe
<span>we count parts
10 meat
9 rice
5 vegetables
sum 10 + 9 + 5 = 24 parts
10/24 meat
9/24 rice
5/24 vegetables
</span><span>Prices determine multiplying 60,000 by a fixed value of the fraction
</span><span>
60.000 *10/24 = 600 000/24 = 25 000 meat
60 000 * 9/24 = 540 000/24 = 22 500 rice
60 000 * 5 = 300 000/24 = 12 500 vegetables
check 25 000 + 22 500 + 12 500 = 60 000
