Answer:
b = (c-3a)/2
Step-by-step explanation:
3a+2b =c
Subtract 3a from each side
3a-3a+2b =c-3a
2b = c -3a
Divide each side by 2
2b/2 = (c-3a)/2
b = (c-3a)/2
If it rose to 15 you should do 87+15 because it was higher
Answer:
8.66
Step-by-step explanation:
root 75 is also 5 root 3 (after simplifying)
when that is converted into a decimal we get
8.660254038...
Rounding to the nearest hundred of that number we focus on these two numbers
8.6<u><em>60</em></u>254038...
As a result to the nearest hundreth is 8.66
If width of rectangle is a, then length is 4a and area = 4a2<span> which is given as 100 m</span>2<span>. So a=5. Perimeter of rectangle= a+a+4a+4a = 10a= 50m</span>
