Answer:
Step-by-step explanation:
I'm not really good in math but I believe its Supplementary because same side interior angles sum up to 180. So if there is an unknown same side angle and the other sameside is given then you set there sum to 180.
Answer:
Step-by-step explanation:
Let the first number = x
Let the second number = y
x + y = 24
<u>7x - y = 16 </u> Add these two equations
8x = 40 Divide by 8
8x/8 = 40/8
x = 5
The smaller number will be 5
================
5 + y = 24
y = 19
==================
Proof
7*5 - 19 = 16
35 - 19 = 16
What are the other expressions then I can help
Answer:
v = 12121 m per week.
Step-by-step explanation:
Given that,
The object is moving at a speed of 2 centimeters every 7 seconds.
We need to find the speed in m per week.
2 cm = 0.02 m
1 week = 604800 s
7 s = ![1.65\times 10^{-6}\ week](https://tex.z-dn.net/?f=1.65%5Ctimes%2010%5E%7B-6%7D%5C%20week)
Speed = distance/time
So,
![v=\dfrac{0.02\ m}{1.65\times 10^{-6}\ week}\\\\v=12121.21\ m/week \\\\or\\\\v=12121\ m/week](https://tex.z-dn.net/?f=v%3D%5Cdfrac%7B0.02%5C%20m%7D%7B1.65%5Ctimes%2010%5E%7B-6%7D%5C%20week%7D%5C%5C%5C%5Cv%3D12121.21%5C%20m%2Fweek%20%5C%5C%5C%5Cor%5C%5C%5C%5Cv%3D12121%5C%20m%2Fweek)
So, the speed of the object is 12121 m per week.
