Answer:
Kendal will be 60 meters away from the library after 80 seconds and again after 100 seconds.
Step-by-step explanation:
6s -540 = 60 or 6s - 540 = -60
<u>First equation</u>
addition property of equality: 6s -540 + 540 = 60 + 540
simplify: 6s = 600
division property of equality: 6s/6 = 600/6
simplify: <em>s = 100</em>
<u>Second equation</u>
addition property of equality: 6s -540 + 540 = -60 + 540
simplify: 6s = 480
division property of equality: 6s/6 = 480/6
simplify: <em>s = 80</em>
Answer:
The solution to the system of equations is:
Step-by-step explanation:
Given the system of equations
Multiply -x+8y=22 by 5: -5x+40y=110
so adding the equations
solve 36y = 144 for y:
divide both sides by 36
Simplify
For 5x-4y=34 plug in y=4
Add 16 to both sides
Simplify
Divide both sides by 5
Simplify
Therefore, the solution to the system of equations is:
12y-2
-6p+2.5
-18+1.75r
-20b+2.4
Answer:
An expression that represents repeated multiplication of the same factor is called a power.
Step-by-step explanation:
The number 5 is called the base, and the number 2 is called the exponent. The exponent corresponds to the number of times the base is used as a factor.
