The sum of two irrational numbers is always rational
sqrt (2) + sqrt)2) = 2sqrt(2) irrational
False
For easier notation lets use: Nn=x and Nd=y
x+y=22
5x+10y=135
Multiply the first equation by 5 to get
5x+5y=110
Now you can eliminate x by subtracting the first equation from the second
5x+10y-5x-5y=135-110
5y=25
y=5
x=17

Converting Units and Comparing Quantities:
The truck cannot pass safely under the bridge. The truck is 13 inches taller than the maximum height.
Step-by-step explanation:
Maximum height of vehicle to pass bridge, (A) = 12 feet 5 inches = (12 x 12) + 5 = 144 + 5 = 149 inches
A Truck's height (B) = 162 inches
The difference between height of Truck and maximum height of allowed vehicle = (A - B) = 13 inches (162 - 149)
Therefore, the truck is higher than the bridge by 13 inches, and cannot pass the bridge.
For the truck to pass the bridge, it must be below 149 inches.

Answer:
9/16
Step-by-step explanation:
After the first exchange the amount in dollars is ...
£320 × $1.25/£1 = $400
After the spending, the amount in dollars is ...
$400 -100 = $300
After the second exchange, the amount in pounds is ...
$300 × £0.60/$1 = £180
This amount is 180/320 = 9/16 of the original amount.
Step-by-step explanation:
A = 1/2h(b1 + b2)
2A = h(b1 + b2)
h(b1 + b2) = 2A
h = 2A/(b1 + b2)
