7 hours later.
If her rate is
6km/hour
then if we do some simple math
6/1=42/7
In 7 hours Amanda will b finished with the marathon
Answer:
b=200 and m=200
Step-by-step explanation:
There are many answers to this problem. You can replace b and n for the number 200. You need to find what two numbers, added up, will give you 400. If b=200 and m=200, when added up, it will give you 400.
2m⁴ - 18n⁶
2(m⁴) - 2(9n⁶)
2(m⁴ - 9n⁶)
2(m⁴ - 3m²n³ + 3m²n³ - 9n⁶)
2[m²(m²) - m²(3n³) + 3n³(m²) - 3n³(3n³)]
2[m²(m² - 3n³) + 3n³(m² - 3n³)]
2(m² + 3n³)(m² - 3n³)
Answer:
4 pull ups and 32 push ups
Step-by-step explanation:
Point-slope form is y1 - y2 = m(x1 - x2). We know that the slope is 2, and we have a point of (1, -1). If we plug in our numbers, we will get y -(-1) = 2(x - 1). This gives us y + 1 = 2(x - 1). Therefore, the answer is B.
