Answer:

$x=20\°$

Step-by-step explanation:

Given:

Angles of triangle: 105° and 55°

$x$ is the missing angle of the triangle.

We know that sum of all three angles of a triangle =180°

∴ $x+105\° +55\° =180\°$

$x+160\° =180\°$

Subtracting 160° from both sides.

$x+160\°-160\° =180\°-160\°$

∴ $x=20\°$

Salvador wrote 15 letters to friends each month for p months in a row. Write an expression to show how many total letters Salvad

katovenus [111]

Answer:

15p

Step-by-step explanation:

Let's interpret the question bit by bit

Salvador wrote 15 letters to friends each month

=> 15 letters = 1 month

For p months in a row

let the total number of letters for p months be x

=> x letters = p months

Bringing the two statements together gives;

15 letters = 1 month

x letters = p months

Now, let's solve for x by cross-multiplying the above

x letters * 1 month = 15 letters * p months

x = $\frac{15 letters * p months}{1 month}$

x = 15p letters

Therefore, Salvador wrote a total of 15p letters for the p months.
