We need to do a system of equations here.
x + y = 275 (if you travel <em>x</em> km by bike and <em>y </em>km by bus, then you travel 275 km as given in the problem)
y = x + 55 (the problem stated that they were bussed (y) the amount they biked plus 55 more km (x + 55))
The second equation is already solved for y. So, we can plug it in to the first equation.
x + (x + 55) = 275
2x + 55 = 275 [combine x terms]
2x = 220 [subtract 55 from both sides]
x = 110 [divide by 2 to isolate x and solve for it]
Now we know that x is 110, the distance they traveled by bike.
And that's what we needed to answer the problem!
Hey You!
You know 27 is closer to 30 because the number is above 25, and it would take 7 blocks to get closer to 20 and only 3 to 30.
Answer:
Answers below
Step-by-step explanation:
7. Area of shape - area of small shape
A(s) = 5*5 = 25 - A(ss) = 3 = 25-3 = 22
8. Area of shape - area of small shape
A(s) = 4*2 = 8 - A(ss) = 1 = 8-1 = 7
3x^7
I hope this helps. I usually good with math so you can ask me whenever
Answer:
When you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. f(x) = x2 and f(x + h) = (x + h)2 Therefore, the slope of the secant line between any two points on this function is 2x + h.
