Given that the perimeter is 16ft and width is 5 ft,
Distribute 2:
Take away 10 from both sides:
Evaluate the right hand side:
Divide by 2 on both sides:
If the triangle's sides are given by
<span>2x-3
x-12
7x+1
Then all you have to do is to add them up, simplify your result and compare your result to each of:
</span><span>a. -10x + 14
b. 9x- 14
c. 10x +14
d. 10x - 14
Adding together the following, we get:
</span><span> 2x-3
x-12
7x+1
---------
10x -14</span>
13)
let assume # denotes angle signs
now
as sum of 3 angels in triangle is 180
#2 +#3 +#4 = 180
also
#1 + #4 = 180
so equating both equation
#2 +#3 + #4 = #1 + #4
#4 will be cancelled from both side then
#2 + #3 = #1
proved
14)
ratio is 1:3:5
so Alma adsed it wrong. it should be 9x in 2nd line.
correction
x + 3x + 5x = 180
9x = 180
x = 180/9 = 20
so 1st angle = x = 20
2nd angle = 3x = 3×20=60
3rd angel = 5x = 5×20 = 100
So first truck transports x amount 12 times or 12x
second truck transports y amount 14 times or 14y
so difference between first and second truck=12x-14y
(note: the problem did not say that the last load of each truck was full so this might be wrong)
Answer: 1/2, 4/8...
Step-by-step explanation: because the least factor is 1/2 so all the numbers and their multiplicity of 2.
