Answer:

Step-by-step explanation:

Exterior angle of a triangle is equal to the sum of opposite interior angles

13b - 48 = (9b - 47) + (b + 44)

Add the like terms

13b - 48 = 10b - 3

Add 48 to both the sides

13b - 48 +48 = 10b - 3 +48

13b = 10b + 45

Subtract 10b from both sides

13b - 10b = 10b + 45 - 10b

3b = 45

Divide both sides by 3

3b/3 = 45/3

b = 15

Answer:

b=15

Step-by-step explanation:

Since the angle with measurement is the exterior angle than the the two other angles added up are equal to it. When you add it up it becomes a simple equation where b=15.

Question is Incomplete, Complete question is given below,

Murphy loves pistachio nuts. Every Saturday morning, she walks to the market and buys some. Last week, she bought two pounds and paid $7.96, and this week she bought only one-half pound and paid $1.99. What the unit rate for pistachio nuts?

Answer:

The unit rate for pistachio nuts is $3.98.

Step-by-step explanation:

Given;

Price of 2 pounds of pistachio nuts = $7.96

We need to find the price of 1 pound of pistachio nuts.

To find the same we will use the unitary method,

Hence ,

Price of 1 pound of pistachio nuts = $\frac{\$7.96}{2} = \$3.98$
