Answer:
The measure of the angle “B” is (d) 70*
Step-by-step explanation:
Let t = # of tricycles; let b = # of bikes.
# of trike wheels is 3t; # of bike wheels is 2b. Total number of wheels is 79, which equals 3t + 2b. t+b = 28, so t=28-b.
Subst. 28-b for t in the first equation:
3(28-b) + 2b = 79. Then 84-3b + 2b = 79, or 5 = b (answer)
There were (28-5) = 23 trikes, 5 bikes, and 28 seats.

Numbers are 5 and 7
Step-by-step explanation:
- Step 1: Let the two consecutive odd integers be x and x + 2. Their sum = 12
x + x + 2 = 12
2x + 2 = 12
2x = 10
x = 5
and x + 2 = 7
