Answer:
420.25
Step-by-step explanation:
If the perimeter is 82, each side is 20.5. Then you do 20.5 x 20.5 to get 420.25.
The next arrival of both deliveries will be in 20 days as 20 is the LCM (lowest common multiple) of 10 and 4.
Pat has $267.21. All you had to do was subtract the 2 numbers
1. using 2 dots that are on the blue line (0,72) and (6,69)
find the slope:
slope = change in Y over change in x = 69 - 72 / 6-0 = -3 / 6 = -1/2
equation would be y = -1/2x + 72
2. y = -1/2x+72 = -1/2(30) +72 = -15 +72 = 57 beats per minute
3. replaced x in the equation with 30 to find the beats per minute for exercising 30 minutes
The system of equations that represent the situation are 1.20R + 2B = 70, and R + B = 90.
<h3>What are the system of equations?</h3>
The system of equations are sets of equations that have to be solved simultaneously in order to determine their required values. They are often referred to as simultaneous equations.
