Answer:
r = 9

The error happened when -3 was multiplied by -r in the first step, negative and negative makes a positive so it should have been
-18 + 3r= 9 in the second step.
Hope this helps :)

A picnic table was originally priced at 40, but Megan waited to buy the picnic table on sale from 75% off. If she paid 10% sale
Mila [183]

<u>Answer:</u>

she spent total price of 13 on the picnic table

<u>Explanation: </u>

Original price of the table = 40

Since she paid 10% of the sale tax after the sale then the total amount she spend is  

Discount = (discount percentage – sale tax  ) × original price

=  (75% -10%) × 40

= 65 % ×40

=\frac{65}{100} \times 40

=26

Hence after the discount amount  

Original price – discount price

= 40-26 = 13

Hence she spent total price of 13 on the picnic table

What is the area of the figure?<br>​
Oksi-84 [34.3K]

Answer:

5.4 in.

Step-by-step explanation:

Figuring out the area of shapes like these are quite simple, you first have to break apart this shape to make solving this easier. If you draw a line and break off the triangle from the square you will get 2 different shapes. A square with all the sides being 2 inches, and a triangle that is 2 inches tall and 1.4 inches across (you subtract 3.4 by 2). Next you just use the equation (2 * 2) + ((1.4 * 2)/2). Multiply 2 by 2 (which is 4) and you get the area of the square (you multiply the base by the width). And for the triangle you multiple 1.4 by 2 (you get 2.8)... But because it's a triangle you have to divide that number by 2 since the triangle is half of a square. So 2.8 / 2 is going to be 1.4. After that you now have the equation 4 + 1.4 and the answer is going to be 5.4.

How do I solve The sum of a number and 3 is subtracted from 10 the result is 5
meriva

State the given in the question

Given that the sum of a number and 3 is subtracted from, the result is 5

State what is to be found in the question

We are to find the number. In other to achieve this, we would follow the steps below:

Step 1: Represent the number with an unknown

Let x represent the number

Step 2: Interpret the given statement mathematically

If x is the number, then the sum of the number and 3 would be

x+3

Then the sum of a number and 3 subtracted from 10 would be

10-(x+3)

Finally, when the sum of a number and 3 subtracted from 10, the result is 5, would be

10-(x+3)=5

Step 3: Solve for x in the mathematical interpretation of the given statement

The value of x is as calculated as shown below:

\begin{gathered} 10-(x+3)=5 \\ \text{Open the bracket or the parenthesis} \\ 10-x-3=5 \\ \text{collect like terms} \\ 10-3-5=x \\ 7-5=x \\ 2=x \\ \text{Therefore:} \\ x=2 \end{gathered}

Hence, the number is 5
