Answer:
17
Step-by-step explanation:
Remark
In this formation, the chords cut each other so that
Equation
(3x - 1) * 3 = 12*(x -2) Remove the brackets.
Solution
9x - 3 = 12x - 24 Add 24 to both sides.
9x - 3 + 24 = 12x - 24 + 24 Combine
9x + 21 = 12x Subtract 9x from both sides
9x - 9x +21 = 12x - 9x
21 = 3x Divide by 3
21/2 = 3x/3
7 = x
Find QR
QR = 12 + x - 2
QR = 10 + 7
QR = 17
Well 361 is 19^2 so the square root of 361 is 19 and is not irrational.
Therefore, the square root of 254 is irrational.
The first blank is 3
the second blank is 5
therefore the same things cannot add up to 2 and 8 at the same time
Let's say Miles Carlos drove = x and taook time = t1
Miles <span>Maria drove = y and took time = t2
But the total mile both drove = 233 and took time = 4.4 hrs
So , x + y = 233
t1 + t2 = 4.4
However, speed = distance / time
for Carlos, 55 = x / t1
for Maria, 50 = y / t2
</span><span>x + y = 233
</span><span>55 t1 + 50 t2 = 233
</span><span>t1 + t2 = 4.4
</span>50 t1 + 50 t2 = 220
5 t1 = 13
t1 = 2.6 hrs for Carlos
t2 = 1.8 hrs
Therefore Maria drove 4.4 hrs
