Answer:
y=3x+1
Step-by-step explanation:
3/15 = 4/16 to the nearest 1/4
5(k+4)-2k
Multiply the k and the 4 by 5
Now you have 5k+20-2k
Minus 2k from 5k
Now you have 3k+ 20 that’s the answer
2(3+d-1)
Multiply 3, d, and 1 by 2
Now you have 6+2d-2
Minus 2 from 6
Now you have 4+2d that’s the answe
Use PEMDAS form. (Parentheses, exponents, multiplication, division, addition, subtraction.) You will first solve -2-8 which is -10, then finish with 9 + (-10), or 9-10, which is -1. The answer is -1.
