5000 meter because there is 1000 meters in 1 kilometer
7d = 56 minus the x in the middle
X: earn per hour during the week
y: earn per hour during the weekend
13x + 14y = 250.90
15x + 8y = 204.70
Multiply the first equation by 4 and the second equation by 7
52x + 56y = 1003.6
105x + 56y = 1432.90
Subtract the first equation from the second:
53x = 429.30
x = 429.30/ 53
x = 8.10
Solve any of the equation for y:
15x + 8y = 204.70
y = [204.70 - 15(8.10)]/8 = 10.40
y - x = 10.40 -8.10 = 2.30
Answer: she earns $2.30 per hour more during the weekend than during the week.
Answer:
= 85
Step-by-step explanation:
given m = - 2, and n = -4
Substitute the given values into the polynomial expression:
![[(-2)^{4} + 5] - (-4)^{3}](https://tex.z-dn.net/?f=%5B%28-2%29%5E%7B4%7D%20%2B%205%5D%20-%20%28-4%29%5E%7B3%7D)
= (16 + 5) - (-64)
= 21 + 64
= 85
Therefore, the correct answer is 85.
Answer:
7.406
Step-by-step explanation:
It is 7.406 because 7x1 is 7, 4/10 is 0.4, and 6/1000 is 0.006. If you add those together, you will get 7.406.
