Step-by-step explanation:
for the perimeter...
18-6=12
that's to get the slant side
perimeter=10+6+12+12+20
=60
for the area I'm not sure how to solve it sorry!!
Length: 12
Width: 4 since 12x4=48 and length is 3 times as long as it is wide.
Hey there!
To order them from least to greatest, we can convert them each into decimals.
To convert a fraction into a decimal, simply divide the numerator by the denominator.
1)
![\frac{3}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B5%7D%20)
To convert
![\frac{3}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B5%7D%20)
into a decimal, simply divide the numerator which is 3, by the denominator which is 5.
3 ÷ 5 = 0.6
So,
![\frac{3}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B5%7D%20)
is equal to 0.6 as a decimal.
2)
![\frac{3}{7}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B7%7D%20)
To convert
![\frac{3}{7}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B7%7D%20)
into a decimal, simply divide the numerator which is 3, by the denominator which is 7.
3 ÷ 7 = 0.43 approximately
So,
![\frac{3}{7}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B7%7D%20)
is equal to 0.43 as a decimal. (approximately)
3)
![\frac{3}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B4%7D%20)
To convert
![\frac{3}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B4%7D%20)
into a decimal, simply divide the numerator which is 3, by the denominator which is 4.
3 ÷ 4 = 0.75
So,
![\frac{3}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B4%7D%20)
is equal to 0.75 as a decimal.
![\frac{3}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B5%7D%20)
⇒ 0.6
![\frac{3}{7}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B7%7D%20)
⇒ 0.43
![\frac{3}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B4%7D%20)
⇒ 0.75
So, from least to greatest, the order is:
![\frac{3}{7}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B7%7D%20)
,
![\frac{3}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B5%7D%20)
,
![\frac{3}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B4%7D%20)

I'm not sure how to solve #2.

bearing in mind that
standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient
then we'd end up with 6x + y = 19.
