38.5
step-by-step explanation:
lets say, first number = r
second number = 3r+7
total = 49
(r)+(3r+7)= 49
4r+7 = 49
4r = 42
r = 42/4
r= 10.5
3r+7 = 3(10.5)+7 = 38.5

which expression represents the approximate length of bc?
y < -3
-3y - 2 > 7
-3y -2 + 2 > 7+2
-3y > 9
-3y/-3 < 9/-3 (change the inequality sign when multiplying or dividing by a negative number)
