Answer:
$2000
Step-by-step explanation:
For each pound, the charge is $40. There are 50 such charges. The point of multiplication is to simplify the process of repeated addition.
... 50 × $40 = $2000
The merchandise shop sells 80 CDs for every 1 vinyl record. We have to find how many vinyl records they are likely to sell if the merchandise shop sells 760 CDs:
80 CDs -------------------- 1 vinyl record
760 CDs --------------------- x vinyl records
---------------------------------------------------------
80 : 760 = 1 : x
80 x = 760
x = 760 : 80
x = 9.5 or 9 ( we need a whole number )
Answer: They are likely to sell 9 vinyl records.
SOLUTION
Write out the equation

To solve this system of equation, the aprropriate method will be substitution
Substitute the expression for y into the second equation for y, we have

Expand the paranthesis we have

Divide both sides by 4, we have

Since the value of x has been obtained, we substitute into the first equation

Therefore
x = -3, y= -4
Hi!
When we write a number in scientific notation, we write it like this:
N × 
N = a number between one and 10
x = negative if the decimal is moved to the right. positive if moved to the left.
Okay, so
we need to move the decimal in the number <span>0.0059
to the right to make it
between one and 10.
0.0059
00.059
000.59
0005.9
5.9N = 5.95.9 </span>×

Since we moved the decimal to the right 3 times,
x = -35.9 × 
^ the answer
Hope this helps! :)
