First question:
Your total restaurant bill is the items you have purchased
plus the sales tax and plus the tip (if there’s any). Sales tax is added to
your purchase because this is tax imposed to the consumer and not to the buyer.
The buyer is only required to collect this tax from the buyer.
Second question:
A check is a financial instrument wherein the bank is
required to pay when presented or encashed to them. You just have to make sure
that you have account balance to that certain bank.
Third question:
The way of payment not any more common in the most modern
economies is the bartering. Both credit cards and cash are the most common way
of paying for your purchases.
Answer:
1. 20x+40
2. 6f+6g
3. 77-28x
Step-by-step explanation:
<u>Use distributive property for all</u>
1) 10(2x+9)-50
20x+90-50
20x+40
2) 6(f+g)
6f+6g
3) 77-28x
4) 3.2(5w+3)
16w + 9.6
This breaks down into a system of equations. George will equal G, Sam will equal S and Alex will equal A. G=S+2 S=A+3 G+S+A=35 since S=A+3, we can substitute S for (A+3). If we plug that into the G=S+2, we get G=(A+3)+2. This simplifies to G=A+5.
our ultimate goal is to be able to substitute for two of their ages so we can solve the last equation for one age or variable. It would be easiest to solve for A.
so far we can substitute for two variables, S=A+3. and G=A+5
Next, we can plug this into the last equation and get 35=(A+3)+(A+5)+A
if we add like terms we get 35=3A+8. Next, we solve the equation by first subtracting 8 from each side. we then get 27=3A, then we divide each side by 3 to solve for A and get A=9.
Now we have one age, we need to find the other two. We can solve this by plugging A to the other two equations. if we do that we get S=(9)+3, or S=12. If we do it to the other equation we get G=(9)+5, or G=14
So your final answer would be George is 14, Sam is 12, and Alex is 9.
<u><em>Answer:</em></u>
DE is the common side in the two triangles
<u><em>Explanation:</em></u>
The side of the triangle is named based on its start and end points
A triangle is named based on its three vertices where each two vertices would join forming a side
<u>For ΔDEC, the sides are:</u>
DE, EC and DC
<u>For ΔEDB, the sides are:</u>
ED, DB and EB
By comparing the two triangles, we would find that DE is the common side in both triangles

Answer:
The answer is D. Natural
Step-by-step explanation:
A subset, mathematically, means a category within another set. This can be shown from the picture below.
As you can see, the subset of whole numbers is, in fact, natural numbers.
