Answer:
b2 = 1
Step-by-step explanation:
A = h(b1 + b2)
Given:
A = 16
h = 4
b1 = 3
b2 = x
Work:
A = h(b1 + b2)
16 = 4(3 + x)
16 = 12 + 4x
4x = 16 - 12
4x = 4
x = 1
The expression 5x+3 would be three more than five times a number! More than in this case would be addition - so if you get the same problem with subtraction you just change more to less!
Basically what it's tell you is that if x stood for 2 in this case 5*2 = 10 since it's 3 MORE than 5 times a number (x is in place of a number), you're adding 3 to 10 and that gives you 13!
I hope I simplified it a little more and you understand!
Good luck, rockstar! c: I hope this helped!
