Hello!
To find the total cost, we will need to multiply the cost per square meter, by the total area. To find the area we will use the formula A=<span>πr</span>². We will use 3.14 for pi.
We know that 2.1 is our radius. We will square it and then multiply it by 3.14.
2.1²=4.41
4.41(3.14)≈13.85
Our area is about 13.85. Now we will multiply by $1.70 to find the total cost. This gives us about $23.55.
The total cost of the glass would be about $23.55.
I hope this helps!
X + Y + Z = 8
2x = Z - 2
X + Z = 5
X = 1
1 + Y + Z = 8
Y + Z = 6
1 + Z = 5
Z = 4
1 + Y + 4 = 8
5 + Y = 8
Y = 3
The variables are 1, 3, 4.

Answer:
x= -1/3
Step-by-step explanation:
First, we can combine like terms on each side:
-4-18x=3x+3
Then, we move all of the variables onto one side and the constant onto the other:
-18x-3x=3+4
-21x=7
x=-7/21
x= -1/3
Hope this helps!
