I'm pretty sure he saved $27. I just divided 90 by 20 to get the amount of times he would have saved 6 dollars. Then, I multiplied that number, 4.5, times 6 to get the amount he saved. Hope that helps (and that it's correct lol). <span />
Answer:
10
Step-by-step explanation:
So what we are doing in this question is simple substitution
So x = 2, y = 4
7x - y
So lets split it up first
7x
7 * (2)
We plugged in 2 for x
This is equal to 14
So the equation is looking like
14 - y
Now lets do the second part
- y
- (4)
We plugged in 4 for y
So no our equation looks like
14 - 4
= 10
Find the series of the graph. This is where the graph crosses the x axis. They are x = -5, -2, and 0.
Factored: y = x(x+2)(x+5)
The product should have a 1 significant digit.
<h3>Scientific notations</h3>
When multiplying Scientific notations, the significant figure of the final result must be approximated to the scientific notation that has the least decimal place.
From the question given, if we 4.5160 x 10^3, 2.09 x 107, and 5.8 x 10^3 are multiplied, the product should have 1 significant digits since the least decimal value that occur in question is 1dp
Hence the product should have a 1 significant digit.
