Answer:
b = 8
Step-by-step explanation:
23 - 15 = 8
Answer:
Not true
Step-by-step explanation:
x + (2x + 5) = 3(x – 4)+7
Opening bracket on left and side and distributing 3 over (x-4) on right hand side
x+2x+5=3x-3 x 4 + 7
adding like terms
3x+5=3x-12+7
3x+5=3x-5
Hence
5 = -5
Which is not possible , Hence the equation given to us is false.
4/13 because the absolute value would be itself since it is positive. If it was negative then the absolute value would be positive.
