For solving these equation, it is important to isolate the variable to then solve it.
In this first equation,
3(4+x)=x+6
12+3x=x+6
12+2x=6
2x=-6
x=-3
to prove this, just substitute x value back into equation;
3(4-3)=-3+6
3(1)=3
3=3
Same for the next equations;
1+2x-x=x-5+x
1+x=2x-5
1=x-5
6=x
Then substitute this value back into equation;
1+2(6)-6=6-5+6
1+12-6= 12-5
7=7
Hi there! The equation is set up as x + 11 > 1. We can go ahead and solve the problem for x. subtract 11 from both sides. 11 - 11 cancels out. 1 - 11 is -10. That simplifies to x > -10. There is nothing else to do, since the x is already simplified. There. The solution is x > -10.
V = π r² h
V= π (4x+2)² (5x+4)
V = π (4x+2)(4x+2)(5x+4)
V = π (16x²+16x+4)(5x+4)
V= π(80x³+144x²+84x+16)
V= 251.33x³ +452.39x²+263.89x+50.27
Answer:
70 fl oz
Step-by-step explanation:
Find how much is added to the punch bowl.
2 containers and each holds 6 fluid ounces.
2 x 6 = 12
Now find the total amount of liquid by adding the original amount and the amount added.
58 + 12 = 70
