Answer:
A B C
Step-by-step explanation:
Let A,B and C be the number of seats in section A,B and respectively. The situation can be represented by the following system. 1. A+B+C=49,000 2. 25A+20B+50C=1,052,000 and 3. A=B+C
6x - 11 - 2x = -7
4x - 11 - = -7
4x = 11
X= 2
12- 11 -4 -3y = -7
-3 -3y = -7
-3y = -4
Y = -1
It should be 2,-1
Answer:
x²y²+xy²+3+xy+2y²
Step-by-step explanation:
(2x²y²+x²y+xy²+3)-(x²y²+x²y²+x²y-xy-2y²)
1. remove the parentheses (when there’s - in front of an expression in parentheses change the sign of each term of the expression)
2x²y² + x²y + xy² + 3-x²y² - x²y² - x²y + xy - 2y²
2. eliminate the opposites
2x²y² + xy² + 3 -x²y² + xy +2y²
3. collect like terms
x²y² + xy² + 3 + xy + 2y²

<span>Answer:
She (Serena) made 30 grams of 33.33% sugar syrup.
Solution:
10 grams sugar + 20 grams water
As 10 grams of sugar added to 20 grams of water, total mixture became 30 grams.
Percentage of sugar in total mixture (sugar syrup) = 10 grams sugar in 30 grams syrup.
% by mass = [(mass of solute) / (mass of solute + mass of solvent)] * 100
This gives = [(10) / (10+20)] * 100 = 33.33%</span>
