Step-by-step explanation:
4. 3x+7=37, 3x=37-7=30 x=30÷3=10
5. 31=7x-11, 7x=31+11=42 x=42÷7=6
6. 11k-84=92, 11k=92+84=176 k=176÷11=16
7. 4r+13=57, 4r=57-13=44 r=44÷4=11
8. z÷4+16=21, z÷4=21-16=5 z=5×4=20
9. 7=t÷6-3, t÷6=7+3=10 t=10×6=60
The slope/rate of change is m=2
Order of operations in a simplified version is PEMDAS, which parenthesis, exponents, multiplication/division, addition/subtraction. so in your equation, 180 + (6-2), you start with what's inside the parenthesis to get 180 + 4. then skip MD bc there's no multiplication or division and move to AS. there is addition, so do addition. so your answer would be 184. however, the associative property is applicable here, so using PEMDAS is not required.
Answer: x<-1
Step-by-step explanation:
The answer is A!
The 3rd one because the rest you would have to distribute them and for the 3rd one it’s the same
