250 + 0.05(xx) is how much david would make if he sold xx that week
Step-by-step explanation:
i hope this helped :)
I'm not entirely sure about some of these because there could be multiple answers, i think. i'll just leave the ones i can't help you with blank.
1) Begin to (isolate) the (variable) by eliminating the (constant). To eliminate the constant, you want to make it (cancel?) because ___+___=___)
2) (Balance) your equation by doing the exact same thing in the opisite side of the (equal sign).
3) Finish (isolating) the (variable) by eliminating the (coefficient). To eliminate the coefficient, you want to make it (cancel?) because ___x___=___,
4) (Balance) your equation by doing the exact same thing on the opposite side of the (equal sign).
5) Check your answer by (plugging) it in or the _____.
honestly, i find it really amusing that they found a way to break a TWO-step equation into 5 steps ?? but i hope this helps a little!!
Answer:
x=3.50
Step-by-step explanation:
2*3.50=7
7-1=6
3+6=9
9+11=20
f(-2) = 2(-2)² - 8(-2) + 6 = 30
f(-1) = 2(-1)² - 8(-1) + 6 = 16
f(0) = 2(0)² - 8(0) + 6 = 6
f(1) = 2(1)² - 8(1) + 6 = 0
f(2) = 2(2)² - 8(2) + 6 = -2
Use distance = rate x time
Let "t" be the time it took for you to drive to your parent's house at 60mph.
So 60t would be the distance.
And "t+40" would be the time it took for you to get to your parent's house at 50 mph. And that total distance would be 50(t+40).
Since both the distances are the same, this gives us the equation:
60t = 50(t+40)
Simplify: 60t = 50t + 2000
10t = 2000
t = 200 minutes
Driving at 60 mph for 200 minutes equates to a total distance of 200 miles.
