Answer:
y = -4
Explanation:
The initial expression is:
-13 = 4y + 3
So, we need to substract 3 from both sides of the equation:
-13 - 3 = 4y + 3 - 3
-16 = 4y
Then, dividing both sides by 4, we get:
-16/4 = 4y/4
-4 = y
Therefore, the solution of the system is y = - 4.
I assume a unit rate is simply ms^-1 or whatever.
In order to determine m/s one must make the "per whatever" part equal to 1. In this case it is seconds, so we must make seconds equal to 1.
If in 17 seconds it travels 238 metres, that means in 1 second it travels 238/17m=14m
Therefore the unit rate (speed) of the car is 14m/s or 14ms^-1
0.504854369 as a percentage would be 50.4854369%
easiest way to remember: a percentage is a decimal rounded 2 decimal places to the right
rounded to the nearest tenth, the percentage will be 50.5%
if u need more help tell me
Answer:
138
Step-by-step explanation:
Hexagon total angle = 720
170+ 277 + 135 = 582
720 - 582 = 138
The first question answer is 21*10^7
The second question answer is 5*10^2
