7x + 1 = x + 7
7(1) + 1 = 8
1 + 7 = 8
If you substitute 1 for x, the statement is true. Therefore, x = 1.
Answer:
He pays $8.00 regardless and $1.40 for each ride. When we see for each, we typically want to multiply.
A. $8.00 + $1.40 * r
If his parents gave him $26.00, then that is the most Kolby can spend.
$8 + $1.40 * r = $26
Subtracting 8 from both sides:
$1.40 * r = $18
Dividing both sides by 1.40:
r = 12.86
B. Since you can't ride part of a ride, Kolby can only ride 12 rides.
Step-by-step explanation:
Explanation:
The sample mean is not always equal to the population mean but if we take more and more number of samples from the population then the mean of the sample would become equal to the population mean.
The Central Limit Theorem states that we can have a normal distribution of sample means even if the original population doesn't follow normal distribution, But we have to take a lot of samples.
Suppose a population doesn't follow normal distribution and is very skewed then we can still have sampling distribution that is completely normal if we take a lot of samples.
Answer: 9.1
Sqrt(81)=9
So 9.1 is larger!
Thanks!
85 > x-63
This is how you would arrange the problem,
isolate the X by adding 63 to 85 to get 148,
Flip the inequality to <
resulting in X<148.
