Answer:
$11.9
Step-by-step explanation:
We are given;
The cost of the cell phone is $170
Tax rate is 7%
We are required to find how much tax is paid on the cell phone.
The tax rate is 7% of the cost of the cell phone
That is;
7% of $170
also; 7/100 of $170
Thus, tax paid = 7/100 × $170
= $11.9
Thus, the tax paid on the cell phone is $11.9

a) By Pythagoras theorem , h^2 is = a^2 + b^2 where a is the hypotenuse and a and b are the legs.
=) 15^2 = x^2 + y^2
That is the relation
b) area of triangle = 1/2 x height x base
=) 1/2 * x * y = 30
=) xy = 15cm
Let x be the unknown number
2x +7 = 39
2x+7-7 = 39-7
2x = 32
2x/2 = 32/2
x=16
You use the balance method to solve. First, you cancel the +7 by subtracting the 7 ON BOTH SIDES to balance the equation.. After that, you are left with 2x, where you will need to isolate the x by dividing by 2 ON BOTH SIDES to balance it.
Hope this helps
