Answer:
10t + D = 40
Step-by-step explanation:
y = mx + b is the equation of a line in slope intercept form. We'll be using this equation since the slope, or distance traveled, is steady (linear). In this case, the slope is 10 since Sarah's pace is 10 km/hr. m is the slope, so m = 10.
y = 10x + b. However, she needs to run 40 km. So we're going to substitute 40 in for y.
40 = 10x + b. Now, we need to use t instead of x since that's what's been asked of us. (The slope represents the distance traveled over time, so t fits.)
10t + b = 40
b needs to become D, the distance in kilometers.
So now we have 10t + D = 40
The communicative property means that multiplied numbers can be multiplied in any order.
3*2*4 is the same as 2*4*3. The answer will be the same.
So (24 * x) is the same as (x * 24).
Hope this helps! :)
Answer: its C
Step-by-step explanation: cause i did that already
Answer:
Your correct and final answer is (9+x^6) (3+x^3) (3-x^3)
Hope this helps!!!
Alright, to start the problem, we need to know what Gina makes! If Gina worked 32 hours for $24.50 per hour, all we need to do is multiply 24.50 by 32 to get 748, which means that this week, Gina made $748!
Next, we need to look at the chart to see where he falls on income tax. Because Gina made more than $218, she makes too much for line 1. Because Gina made more than $758, she makes too much for line 2.
Because Gina made less than $1762, and more than 753, it looks like Gina will fall into line 3, so your answer should be C!
