I think the answer is 16 because 16 x 3 is 48 and you're supposed to multiply the height by the width

Answer:

question 8 = 6cm

Step-by-step explanation:

$formula (perimeter)= \\ sum \: of \: all \: sides \\ \\ 3x + 3x + x + x = 48 \\ 3(6) + 3(6) + 6 + 6 = 48 \\ 18 + 18 + 6 + 6 = 48$

Subtract fractions with different denominators

Tems11 [23]

Answer:

$\frac{10}{15}-\frac{2}{5}=\frac{4}{15}$

Step-by-step explanation:

We know that

A fraction consists of two integers—one on the top, and one on the bottom.
The top one is numerator, the bottom one is denominator, and
These two numbers are separated by a line.

Let us consider two different fractions with different denominators

$\frac{10}{15}$

$\frac{2}{5}$

Lets subtract the two fractions

$\frac{10}{15}-\frac{2}{5}\:\:\:\:$

$\mathrm{Cancel\:}\frac{10}{15}:\quad \frac{2}{3}$

$=\frac{2}{3}-\frac{2}{5}$

$\mathrm{Least\:Common\:Multiplier\:of\:}3,\:5:\quad 15$

$\mathrm{Adjust\:Fractions\:based\:on\:the\:LCM}$

$\mathrm{For}\:\frac{2}{3}:\:\mathrm{multiply\:the\:denominator\:and\:numerator\:by\:}\:5$

$\frac{2}{3}=\frac{2\cdot \:5}{3\cdot \:5}=\frac{10}{15}$

$\mathrm{For}\:\frac{2}{5}:\:\mathrm{multiply\:the\:denominator\:and\:numerator\:by\:}\:3$

$\frac{2}{5}=\frac{2\cdot \:3}{5\cdot \:3}=\frac{6}{15}$

$=\frac{10}{15}-\frac{6}{15}$

$\mathrm{Since\:the\:denominators\:are\:equal,\:combine\:the\:fractions}:\quad \frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}$

$=\frac{10-6}{15}$

$\mathrm{Subtract\:the\:numbers:}\:10-6=4$

$=\frac{4}{15}$

Therefore,

$\frac{10}{15}-\frac{2}{5}=\frac{4}{15}$

Picture 1: the colonists rights had been trampled over by the British, so they renamed the coercive rights and intolerable rights.
Picture 2: the Boston tea party was not appropriate because colonists wasted so much money on that wasted tea, but they had for the motivation to stand up for their right and to risk their life for independence.

I hope this helped! :)

What is the value of x?<br><br> see attachment below

Kitty [74]

Answer:

x = 31

Step-by-step explanation:

The perimeter is the sum of the equal-length sides:

63 = (x -10) +(x -10) +(x -10)

63 = 3x -30 . . . . . . . . collect terms

21 = x -10 . . . . . . . . . . divide by 3

31 = x . . . . . . . . . . . . . add 10
