Answer:
Avery needs to pay $14.84
Step-by-step explanation:
When there's a tax we need to sum the original value of the product with the tax's value. To find the amount of money Avery needs to pay in taxes we can apply a rule of three as shown below:
Where "x" is the tax value, and $14 represents 100%, since it's the value used to calculate the tax. We have:
The value to be paid is the product value plus the tax, therefore:
Avery needs to pay $14.84
Answer: x = -7
Concept:
From the given graph, we can see that it is an isosceles triangle since the two base angles are congruent.
In geometry, an isosceles triangle is a triangle that has two sides of equal length.
If you are still confused, you may refer to the attachment below for a graphical explanation or tell me.
Solve:
<u>Given information</u>
First Side = 7
Second Side = x + 14
<u>Given expression deducted from the definition of an isosceles triangle</u>
Second Side = First Side
<u>Substitute values into the expression</u>
x + 14 = 7
<u>Subtract 14 on both sides</u>
x + 14 - 14 = 7 - 14
