Let the cost of renting a chair be x and for renting a table be y than 5x + 3y = 31 and 2x + 6y = 52 2x+ 6y = 52 can be further simplified to x + 3y = 26 now try solving for x and y... best of luck:D
Answer:
11 miles
Step-by-step explanation:
After the first hour, they walk 3 more hours at 2 miles per hour. So, the total distance is ...
5 mi + (3 h)(2 mi/h) = 5 mi + 6 mi = 11 mi
The blue team will walk 11 miles in 4 hours.
You can use SAS since you know one pair of sides are congruent and AC splits them so those must make those sides equal. And since those sides, DC and BC, are congruent, the angles must be as well. You can use numbers to prove the angles of D and B or just use that when 2 sides and an angle are congruent, the 3rd side must be congruent.
Answer: 4 V
Step-by-step explanation:
The formula for electrical power 
is:
Where:
is the water heater electrical power
is he water heater voltage
is the electrical resistance
Isolating :
Hence:
14^2 - 9^2 = a^2
Easy enough
14^2 = 196
9^2 = 81
196 - 81 = 115
The square root of 115 = 10.72
The third side is 10.72km
