X+15=3. And if you don’t mind, please look at my recent mathematics question because I am very desperate for an answer
Answer:
93 is your answer.
Step-by-step explanation:
What you want to do is PEMDAS.
<em>3 · 32 + 8 ÷ 2 − (4 + 3)</em>
<em>96 + 8 ÷ 2 - 7</em>
<em>96 + 4 - 7 </em>
<em>100 - 7</em>
93 is your answer.
Ok, find change then divide by years elapsed
change=310-280 million=30 million
number of years elapsed=10
30mil/10=3mil
3million per year was the population growth rate
Answer:
the slope or gradient is 8/2=4
Answer:
m = 1 and b = 5/7
Step-by-step explanation:
Take two of the points. The first two. (7, 5) and (8, 6).
We can find the slope using:
y2-y1/x2-x1
We can sub in the values:
6-5/8-7 = 1/1 = 1
So the slope is 1
now, putting this into y=mx+b, and using one of the coordinates from earlier, we can solve for b:
5 = (1)(7) + b
b = 5/7
Therefore, m = 1 and b = 5/7
Hope this helps!
