Answer:

The part of the expression representing the amount of tax to be paid is;

0.08(507)

Step-by-step explanation:

Here, we want to select the part of the expression that represents the amount of tax Deborah has to pay

From the expression, we have ;

0.08(507) + 50h

Kindly note that we can have 0.08 as 8/100

8/100 is same as 8%

when we represent taxes, it is usually a percentage of something

In that case, the tax part would be ; 0.08(507)

1. The following system has NO SOLUTION. Explain with specific values why the system has no solutions.
vovangra [49]

Answer:

Yea that problem is a bit confusing,

2y should be double of what y is, which is 4x+5

Then 2y says 8x+15, when it should be 8x+10.

I feel bad cause I am sure the teacher is wrong on this, he/she had probably made a typo, or you made a typo, but that's ok! We all make typos!

The teacher would be extra rude if they marked you wrong on this, cause the question itself is not written "properly"

Certain items are purchased jointly. If each person pays 8 coins, the surplus is 3 coins, and if each person gives 7 coins, the
Karo-lina-s [1.5K]

Answer:

7 people purchase the items and they used 53 coins

Step-by-step explanation:

Let x represent the number of people.

Let y be the number of coins needed to purchase the items.

If each person pays 8 coins, the surplus is 3 coins. This is illustrated below:

8x = y + 3 (1)

if each person gives 7 coins, the deficiency is 4 coins. This is illustrated below:

7x = y — 4 (2)

Solving by elimination method: subtract equation(2) from equation (1). This is illustrated below:

8x = y + 3 (1)

— (7x = y — 4) (2)

x = 7.

Next, Substituting the value of x into any of the equation to obtain y. In this case I will be using equation 1 as illustrated below:

8x = y + 3 (1)

8(7) = y + 3

56 = y + 3

Collect like terms

y = 56 — 3

y = 53

Therefore, 7 people purchase the items and they used 53 coins

inn [45]
Based on the scenario, the reduced form of f(n) is : 

f(n) = n^4/4+n^3 + 5n^2/4+n/2

or, it could also be written as

n/4 (n+1) (n^2 + 3n + 2)
