Step-by-step explanation:
Case 1 : |x| > a, => x > a or x < -a
Case 2 : |x| < a, => -a < x < a
Since this question follows Case 1, we will have an "or" inequality.
Children’s tickets are $4, adult tickets are $14
Explanation:
4a+6c=80
If they made $4 more dollars on the second day than the first by selling one extra child ticket then we know a child’s ticket is $4 per ticket.
4a+6*4=80
4a+24=80
4a=56
14=a
So each adult ticket costs $14.
You can check by filling in $14 and $4 for each equation.
4*14+6*4=80
4*14+7*4=84
Answer:
Not accurate
Step-by-step explanation:
3+9+9=21
Answer: A
Step-by-step explanation:
Subtract 12 from both sides:
y + 15 - 15 < 3 - 15
Simplify:
y < -12
The table is missing, so i have attached it.
Also, the correct question is;
The surface area of the East China Sea is k times the surface area of the Baltic Sea.
Work out the value of k.
Give your answer to the nearest whole number
Answer:
k = 3
Step-by-step explanation:
From the attached table,
Surface area of east china = 1.25 × 10^(6) km²
Surface area of Baltic sea = 4.22 × 10^(5) km² = 0.422 × 10^(6) km²
We are told that the surface area of East China Sea is k times that of the surface area of the Baltic Sea.
Thus;
1.25 × 10^(6) = k × 0.422 × 10^(6)
k = 1.25/0.422
k = 2.96
Approximating to whole number gives;
k = 3
