Answers + Step-by-step explanation :
a) the equation should be:
7(n + 5) = 91 since you first add 5 to n and then multiply it by 7. The answer is 91 so that is on the other side of the equal sign
b) we can solve our equation to find for n, the number jim thought of
7(n + 5) = 91
I will use the distributive property.
7n + 35 = 91
Subtract 35 on both sides
7n = 56
Now divide 7 on both sides to find n
n = 8
The number Jim was thinking of was 8! this should be correct, hope this helps!
Answer:
x=11.5
Step-by-step explanation:
You want to isolate x. The first thing you have to do is get rid of that tricky fraction. To do this, you have to multiply the fraction by its denominator to cancel the denominator out and leaving you only with the numerator. You would also have to multiply 3 by 5.5 too. (Multiplying by the denominator only gets rid of the denominator and leaves the numerator alone. However, in your case, the numerator is one, so by getting rid of the denominator you get 1x. This can just be written as x.)
Equation would look like this:
x+5=16.5
You subtract 5 from both sides, and 16.5 minus 5 is 11.5
Equation would now look like this:
x=11.5

Bar charts and histogram</h3>
From the given histogram, the data of the distribution will be given as:
- 1, 2, 3, 3, 4, 4, 4, 4, 5, 5, 5, 5, 5, 6, 6, 6,7, 8, 9,9 10
The median of the distribution is the number in the middle.
Median = n+1/2 th number
Median = 21+1/2
Median = 22/2 = 11th number
Hence the 11th number in the data is 5.
