So remember that parallel lines have the same slope. And since Line a's slope is 5/7, and line a and b are parallel to each other, this means that line b's slope is 5/7.

Find the least common multiple of these two expressions. 10v^6y^7 and 6w^4v^5y^3

egoroff_w [7]

10v⁶y⁷ = 2 * 5 * vvvvvv * yyyyyyy

6w⁴v⁵y³ = 2 * 3 * wwww * vvvvv * yyy

GCF: 2v⁴y³

The LCM is the GCF and everything leftover

LCM: 2v⁴y³ * (5 * v * yyyy) * (3 * wwww)

= (2 * 5 * 3) * (v⁴ * v) * (w⁴) * (y³ * y⁴)

= 30 v⁵ w⁴ y⁷

Answer: LCM = 30v⁵w⁴y⁷

Dr.Bolton was born in an interesting year. The tens digits was twice the thousands digits, the ones Digits was three times the t

kap26 [50]

Answer: Dr. Bolton was born in 1926.

Work:

Let x be the thousands digit. So, you will have the tens digit be 2x, the ones digit be 6x, and the hundreds digit be 9x. Now, let's try x as 1. Then, you will have the thousands digit be 1, the tens digit be 2, the ones digit be 6, and the hundreds digit be 9. Hope it helps!
