Separate the figure into the two shapes: a square and a trapezoid.

The sides of a square are all equal.
Therefore the square has a perimeter of 30 inches (because only three of its sides make up the whole shape)

An isosceles trapezoid has two sides that are equal: the two sides that are opposite each with length 5.

This means that 5 + 5 + 4 = 14.

Add the two perimeters up and you get 44inches.

What is 45=m(25)+b solving for m

STatiana [176]

Answer:

$\frac{45-b}{25}$

Step-by-step explanation:

given

45 = 25m + b ( isolate the term in m by subtracting b from both sides )

45 - b = 25m ← divide both sides by 25

Alfonso is 8 years older than Ashley. Five years ago Alfonso was three times as old as Ashley. How old is Ashley now?

Pavel [41]

Answer: 9 years

Step-by-step explanation:

Let the present age of Ashley be x.

Then the present age of Alfonso =x+8

Five years ago,

Ashley's age = x-5

Alfonso's age = x+8-5 = x+3

According to the question,

$x+3=3(x-5)\\\Rightarrow\ x+3=3x-15\\\Rightarrow\ 3x-x=3+15\\\Rightarrow\ 2x=18\\\Rightarrow\ x=\frac{18}{2}\\\Rightarrow\ x=9$

Hence, the present age of Ashley =9 years
