Answer:
that is the solution is to the question
Hello! So the skateboard was mark up by 100%. This mean that the price of that item doubled. Let's find the new price after that. 37.10 * 2 is 74.2. That's $74.20 after markup. Ellen bought that skateboard with 5% tax. To find out the total amount she paid, multiply 74.2 by 105% (1.05). keep in mind that 100% represents the full price. 74.2 * 1.05 is 77.91. There. Ellen paid $77.91 for the skateboard.
For this case we have the following expression:

We must find the value of the expression when:

Substituting the values in the expression we have:

Thus, the value of the expression is 2.
Answer:
The value of the expression is 2
Option A
Answer:
Two angles that have the same measure are called congruent angles. Here are two angles that both measure 30°. We say that angle x is congruent to angle y.
Step-by-step explanation:
I only know (b) and 28 (c)
(b) Multiples of 120= 120,240,360,480,600
Multiples of 150= 150,300,450,600
Both numbers have 600 as their first common multiple so the ANSWER is 600
28. (a) Common factors of 24= 1,2,3,4,6,8,12,24
Common factors of 64= 1,2,4,8,16,32,64
8 is the only common factor for both 24 and 64 so 8 is the ANSWER
