Answer:
opening the brackets we have;
3t+15+5t+15=-4t-12
collect like terms
3t+5t+15+15=-4t-12
8t+30=-4t-12
8t-4t=-12+30
4t=18
t=18/4
8 pounds
2.50 - 7.75 = 5.25

Answer:
His brother gets 8 apples
His friends gets 4 apples
He gets 12 apples
Step-by-step explanation:
brother: friend himself::total
2 1 3 2+1+3 = 6
He has a total of 24 apples
24/6 = 4
Multiply each term by 4
brother: friend himself::total
2*4 1*4 3*4 6*4
8 4 12 24
His brother gets 8 apples
His friends gets 4 apples
He gets 12 apples
