Answer:
66
Step-by-step explanation:
We can write the following equation to solve

Reduce
360 = 5x + 30
5x = 330
x = 66
Answer:
Tamara incorrectly factored the whole expression.
Step-by-step explanation:
Note that
- 21x=3·7·x;
- 56xy=2·2·2·7·x·y.
Mark in bold all common factors, then GCF(21x,56xy)=7·x=7x.
Thus,
21x+56xy=7x(3+8y).
Hence, Tamara correctly found the GCF of numbers 21 and 56, but incorrectly factored the whole expression.

<h3>The linear equation of the graph</h3>
The equation of the line of best fit is given as:

When the number of pictures added is 700, we have:
y = 700
Substitute 700 for y in 

Subtract 367 from both sides of the equation

Rewrite the above equation as:

Divide both sides by 8

Remove decimal (do not approximate)

This means that:
