47
Step-by-step explanation:
x-5=42
x=42+5
x=47
Answer:
I think that it should be

Step-by-step explanation:
Here,
we take , a - b = A,b-c = B , c - a= C
A+B+C = 0
we know that,

Here , A+B+C = 0
so,
A^3 +B^3 + C^3 = 3 ABC
now we put the values

I am done .
To find how many bottles are plastic just divide 12 by 3. 12/3=4 so 4 is one third of 12.
1500$/750tickets=2$
(2.50$+1.50$)/2=4/2=2$ <span>weighted average
this mean 50 50
750/2=375
</span>375 adult tickets and 375 children's tickets
Y = ax + b;
0.89 = a * 2 + b and 2.09 = a * 5 + b =>
=> 2.09 - 0.89 = a * 5 + a * 2 + b - b => 1.20 = 3 * a => a = 1.20 / 3 => a = 0.40;
b = 0.89 - 0.40 * 2 => b = 0.89 - 0.80 => b = 0.09;
y = 0.40x + 0.09 => 0.40x - y + 0.09 = 0 is the linear equation.
