Answer:

Option: A. The given equation is a linear expression

Solution:

The linear expression is the expression whose highest degree is 1 after combining the degrees of all the terms in the expression.

Here in the problem the expression is $5x$ + 2 which can also be written as, $(5x^{1}+2^{1})$

We can see that the degree of term $5x$ is 1 and the degree of term 2 is also 1

So, the highest degree of the given expression is =1

Hence, the equation is a linear expression.

A store charges 6% VAT on all sales. What is the total cost of a shirt marked at $30

AURORKA [14]

Answer:

$31.8

Step-by-step explanation:

Assuming the 6% tax is separate from the $30, we can use this equation:

Total = Cost + Tax (pretty self explanatory)

Method 1

Total = $30 + (6% * $30)

Total = $30 + $1.8

Total = $31.8

Method 2

Total = $30 * 1.06 (The 1 is the original cost, the .06 is the 6% tax)

Total = $31.8

Express each number in scientific notitatio 43,000= 0.0072= 0.0000901=

Maksim231197 [3]

Answer:

43,000: 4.3×10^4

0.0072: 7.2×10^-3

0.0000901: 9.01×10^-5

Step-by-step explanation:

scientific notation: a×10^b, where should be 0<a<10

Step 1. Count the zeros

Step 2. Look at the number left, and determine whether or not it fits in the range of [a]. If not, we divide or multiply 10 to get it fit

------------------------

43,000: 4.3×10^4 (since 43 does not fit, we divide by 10 to get it fit)

0.0072: 7.2×10^-3 (since 0.72 does not fit, we multiply 10 to get it fit)

0.0000901: 9.01×10^-5 (since 0.901 does not fit, we multiply 10 to get it fit)

Hope this helps!! :)

Ron's recycle shop had an old paper-shredding machine. Business was good, so he bought a new paper-shredding machine. The old ma

levacccp [35]

Answer: 1 hour 20 minutes

Step-by-step explanation:

Given : The old machine could shred a truckload of paper in 4 hours.

Rate of work done by old machine = $\dfrac{1}{4}$

The new machine could shred the same truckload in 2 hours.

Rate of work done by new machine = $\dfrac{1}{2}$

Let 't' be the time taken by both of them working together , then we have the following equation:-

$\dfrac{1}{t}=\dfrac{1}{4}+\dfrac{1}{2}\\\\\Rightarrow\dfrac{1}{t}=\dfrac{1+2}{4}\\\\\Rightarrow\dfrac{1}{t}=\dfrac{3}{4}\\\\\Rightarrow t=\dfrac{4}{3}=1\dfrac{1}{3}\ \text{ hours}$

Since 1 hour = 60 minutes

Then, $\dfrac{1}{3}\ \text{ hours}=\dfrac{1}{3}\times60=20\text{ minutes}$

Hence, it will take 1 hour 20 minutes to shred the same truckload of paper if Ron runs both shredders at the same time.
