Solve the following: a) -5/4 [8/7+16/5]

Otrada [13]

Answer:

-38/7

Step-by-step explanation:

We are given $-\frac{5}{4}(\frac{8}{7}+\frac{16}{5})\\$ . First find the sum of the fractions in the parentheses. The greatest common multiple is 35 so we have $\frac{8}{7}+\frac{16}{5}=\frac{40}{35}+\frac{112}{35}$ .

The sum of $\frac{40}{35}+\frac{112}{35}$ is $\frac{152}{35}$ .

Now we multiply it by $-\frac{5}{4}$ so we have

$\\-\frac{5}{4} \cdot \frac{112}{35}\\=-\frac{1}{7}\cdot \frac{38}{1}\\=\boxed{-\frac{38}{7}}\\$

A student wants to find point C on the directed line segment from A to B on a number line such that the segment is partitioned i

olganol [36]

Answer:

Point C at (-18/7)

Step-by-step explanation:

Point A is at -6 and point B is at 2.

So, the distance between A and B = 2 - (-6) = 8

point C on the directed line segment from A to B on a number line such that the segment is partitioned in a ratio of 3:4.

Let the distance AC = x

∴ BC = 8 - x

AC : CB = 3 : 4

∴ $\frac{AC}{CB} =\frac{3}{4} = \frac{x}{8-x}$

Using cross multiplication

3 (8-x) = 4x

24 - 3x = 4x

24 = 7x

x = 24/7

So, Point C = -6 + 24/7 = -18/7

Point C at (-18/7)
