Galina-37 [17]

Answer:

Step-by-step explanation:

The area of a rectangle is A = lw. 'A', the area, is 3927, and 'w', the width, is 51. By substituting the values in, we get that 3927 = 51L. Dividing both sides by 51, we get that L, the length, is 77.

MAVERICK [17]

Answer:

the simplest form of the given expression is $-1\frac{4}{35}$

Step-by-step explanation:

Given;

$2 \times \frac{1}{7} - 1\frac{2}{5}$

The above expression can be simplified as follows;

$2 \times \frac{1}{7} - 1\frac{2}{5} \\\\=\frac{2}{7} - \frac{7}{5} \\\\= l.c.m \ of \ 7 \ and \ 5 \ is \ 35\\\\= \frac{5(2) - 7(7)}{35} \\\\= \frac{10 - 49}{35} \\\\= -\frac{39}{35} \\\\= - 1\frac{4}{35}$
