![\boxed{ \bold{ \sf{m < AFD = 82}}}](https://tex.z-dn.net/?f=%20%5Cboxed%7B%20%5Cbold%7B%20%5Csf%7Bm%20%3C%20AFD%20%3D%2082%7D%7D%7D)
Step-by-step explanation:
![\sf{5x + 18 = 3x + 50}](https://tex.z-dn.net/?f=%20%5Csf%7B5x%20%2B%2018%20%3D%203x%20%2B%2050%7D)
( Being vertically opposite angles)
Vertically opposite angles are always equal.
Move variable to L.H.S and change it's sign
Similarly, Move constant to R.H.S and change it's sign
⇒![\sf{5x - 3x = 50 - 18}](https://tex.z-dn.net/?f=%20%5Csf%7B5x%20%20-%203x%20%3D%2050%20-%2018%7D)
Collect like terms
⇒![\sf{2x = 50 - 18}](https://tex.z-dn.net/?f=%20%5Csf%7B2x%20%3D%2050%20-%2018%7D)
Subtract 18 from 50
⇒![\sf{2x = 32}](https://tex.z-dn.net/?f=%20%5Csf%7B2x%20%3D%2032%7D)
Divide both sides of the equation by 2
⇒![\sf{ \frac{2x}{2} = \frac{32}{2} }](https://tex.z-dn.net/?f=%20%5Csf%7B%20%5Cfrac%7B2x%7D%7B2%7D%20%20%3D%20%20%5Cfrac%7B32%7D%7B2%7D%20%7D)
Calculate
⇒![\sf{x = 16}](https://tex.z-dn.net/?f=%20%5Csf%7Bx%20%3D%2016%7D)
The value of x is 16
Now, let's find value of m<AFD :
( sum of angle in straight line )
plug the value of x
⇒![\sf{m < AFD + 5 \times 16 + 18 = 180}](https://tex.z-dn.net/?f=%20%5Csf%7Bm%20%3C%20AFD%20%2B%205%20%5Ctimes%2016%20%2B%2018%20%3D%20180%7D)
Multiply the numbers
⇒![\sf{m < AFD + 80 + 18 = 180}](https://tex.z-dn.net/?f=%20%5Csf%7Bm%20%3C%20AFD%20%2B%2080%20%2B%2018%20%3D%20180%7D)
Add the numbers
⇒![\sf{m < AFD + 98 = 180}](https://tex.z-dn.net/?f=%20%5Csf%7Bm%20%3C%20AFD%20%2B%2098%20%3D%20180%7D)
Move constant to R.H.S and change it's sign
⇒![\sf{m < AFD = 180 - 98}](https://tex.z-dn.net/?f=%20%5Csf%7Bm%20%3C%20AFD%20%3D%20180%20-%2098%7D)
Subtract 98 from 180
⇒![\sf{m < AFD = 82}](https://tex.z-dn.net/?f=%20%5Csf%7Bm%20%3C%20AFD%20%3D%2082%7D)
Value of m<AFD = 82
Hope I helped!
Best regards!!
Answer:
P= 7/9 miles
A= (7/18) miles²
Step-by-step explanation:
Length 'l' = (1/6) mile
Width 'w'= (2/9) mile
Perimeter 'P' is given by:
'P' = 2l + 2w => 2(1/6) + 2(2/9)
P= 7/9 miles
Area 'A' is given by:
A= l x w =(1/6) x (2/9) = (7/18) miles²
Answer: $700
Step-by-step explanation:
The store is selling at 30% off.
If a mattress is $1,000, first find out what 30% of $1,000 is:
= 1,000 * 30%
= $300
The store is selling 30% off, this means that they are reducing the price by 30%:
= 1,000 - 300
= $700
2.8 = 2 + 0.8
*let's analyze the decimal 0.8 as a fraction
0.8 = 8/10
*but if we divide the numerator and denominator by the same common factor of 2, we find that the fraction can be reduced to:
(8/2)/(10/2) = (4)/(5) = 4/5
*now evaluating the whole value of 2 (from the 2.8), we know there are a total of (5) - fifths in order to make a whole, so for 2 whole, we require:
2*(5/5) = (2*5)/5 = 10/5
*Now we add the fractions together:
2 = 10/5
0.8 = 4/5
10/5 + 4/5
*add numerators only, the denominator stays as a 5
(10 + 4)/5 = 14/5
*there are no common factors between 14 & 5 (other than 1, but that won't help reduce the fraction any), so the fraction is in it's simplest form:
answer is: 14/5
