Answer 2

$\huge\red{\underline{ \underline{Answer :}}}$

1) (-2/3) × (1/5) = .

$\frac{ - 2}{ \: \: \: 3 } \times \frac{1}{5} \\ = \frac{ - 2 \times 1}{ \: \: 3 \times 5} \\ = \frac{ - 2}{15} \: \: \: \: \: \: \: \:$

$\boxed{B) \large \: \: \frac{ - 2}{ \: \: 15} }$

2) Reciprocal of 3/2 = .

$reciprocal \: \: of \: \: \frac{3}{2} = \frac{2}{3} .$

$\boxed{B) \large{\: \: \frac{2}{3} }}$

3)X + 3 = 7, X = _______.

$x + 3 = 7 \\ x = 7 - 3 \\ x = 4 \: \: \: \: \: \: \: \: \:$

$\boxed{C) \: \large 4}$

4) The sum of the measures of the four angles of a quadrilateral is

360°

$\boxed{D) \: \: \large360°}$

5)Square root of 49 is .

$\sqrt{49} = 7 \\ (7 \times 7 = 49)$

$\boxed{C) \: \: \large 7}$
