What you can do is see it like this 20x50 or take 5x2 which is 10 and then count how many zeroz there are in the original equation and add them. Since there are 2 zeros you add them to the 10, so the answer will be 1000.
Answer:
The answer is $20.21
Step-by-step explanation:
So first you find the subtotal cost of the lunches. Each lunch costs $20, so that would be $40 in total.
Now you find the total cost.
She has to pay 5% sales tax so to find the total, you have to multiply 40 by 0.05. That gives you a total of $2. Then you add that to your $40 to get $42.
Now for the tip.
It says to find 10% of 20, so you have to multiply 20 by 0.1. That equals 0.208. Then you add that to 20 to get 20.208.
If you round off, you get a total of $20.21
We have that
<span>f(x)=-x+0.5
g(x)=x</span>²+3x-4
f(x)=g(x)------------> -x+0.5=x²+3x-4-------------> x²+3x-4+x-0.5=0
x²+3x-4+x-0.5=0---------------> x²+4x-4.5=0
using a graph tool
see the attached figure
the solution are the points (-4.915,0) and (0.915,0)
