Answer: B
Explanation:
x = 3
You need to plug x into the equation
y = 3(3)+15
y = 9+15
y= 24
Answer:
12 hours
Step-by-step explanation:
15/2=7.5
90/7.5 = 12
Firstly you should add the like terms i.e. 5x + x. So The answer will be 6x + 2. If it requires you to factorise then take out the highest common factor i.e. 2. So factorised the answer will be 2(3x + 1).
The answer to this equation will be 359
