The number of stamps and the cost are illustrations of unit rates
40 stamps would cost $22
The cost of 15 postage stamps is $8.25
Start by calculating the unit rate of the stamps.
So, the number of stamps for $22 is calculated by dividing $22 by the unit rate.
So, we have:

Answer:
b = 24 meter
Step-by-step explanation:
Using Pythagoras theorem:
a² + b² = c²
Here given: a = 10 m, b = ?, c = 26 m
<u>Insert values</u>
10² + b² = 26²
b² = 26² - 10²
b² = 676 - 100
b² = 576
b = √576
b = 24
Answer:
13.01 d -2.65
Step-by-step explanation:
3.26d + 9.75d - 2.65
Combine like terms
3.26d + 9.75d - 2.65
13.01 d -2.65
Answer:
j = 175
Step-by-step explanation:
Step 1: Write equation
35 = j/5
Step 2: Multiply both sides by 5
35(5) = j/5(5)
175 = j
Step 3: Rewrite
j = 175
