7+3x=2x+2
Send constants to one side and others to one side
3x-2x=2-7
x=-5
Since a(n)=-3(a(n-1)) the common ratio is -3, and a(1)=-3 so
a(n)=-3(-3^(n-1)) so the first four terms are:
-3, 9, -27, 81
Answer: it’s false there is no solution
Step-by-step explanation:
It has to be 30,40,50
Due to Pythagoras Theron it suggests that longer sides is a*2 and b*2 and 30 and 40 square is 2500
2500 square is 50 meaning it makes this statement true
All others are wrong
Answer:
46 1/2 miles
Step-by-step explanation:
Given that:
Bus traveled at a constant speed ;
Miles traveled = 15 1/2 miles
Time taken for the travel = 1/3 of an hour
Number of miles bus will travel in 1 hours :
Let number of miles traveled in 1 hour = n
15 1/2 miles = 1/3 hour
n miles = 1 hour
Cross multiply :
1/3 * n = 15 1/2 * 1
1/3n = 31/2
Divide both sides by 1/3
n = 31/2 ÷ 1/3
n = 31/2 * 3/ 1
n = 93/2
n = 46.5 miles = 46 1/2 miles
