Answer 1

14). 3/8 × 6/4 = 9/16

15). true

${\purple{\underline{\boxed{ \sf{part B}}}}}$

1).if you added 2 to half is p, you get 8

or

two more than half of p is 8

2).(-1,-9) and (-3,-11) are two pairs whose difference is 8. (-1,-9) and (-3,-11) are two pairs whose difference is 8. We can write infinitely many pairs

$3) \: 2 \frac{2}{3} + 3 \frac{1}{2}$

$= \frac{8}{3} + \frac{7}{2}$

$= \frac{16 + 21}{6}$

$= \frac{37}{6} \: or \: 6 \frac{1}{6}$

4)As the first five whole numbers are 0, 1, 2, 3, and 4. Mean = (Sum of observations)/(Number of observations) = (0 + 1+ 2 + 3 +4)/5 = 2.

$5) \: let \: the \: number \: be \: x$

$\frac{1}{5} x - 4 = 3$

$\frac{x}{5} = 3 + 4$

$\frac{x}{5} = 7$

$x = 7 \times 5 \\ = 35$

${\purple{\underline{\boxed{ \sf{Part C}}}}}$

$1). \: 18 \times [7 + ( - 3)] = [18 \times 7] + [18 \times ( - 3)]$

$LHS$

$18 \times [7 + (3)]$

$= 18 \times [7 - 3]$

$= 18 \times 4 \\ = 72$

$RHS$

$[18 \times 7] + [18 \times ( - 3)]$

$= 126 - 54 \\ = 72$

Answer 2

Answer:

Science is what we do to find out about the natural world. Natural sciences include, chemistry, biology, geology, astronomy, and physics. Science uses mathematics and logic, which are sometimes called "formal sciences". ... People who study and research science and try to find out everything about it are called scientists.
