I have no clue. This is because I honestly want more points. So yea thank you for understanding.
Write an expression using multiplication and addition with a sum of 16:
2 x 6 +4
Step-by-step explanation:
h(x)=¾x +12
let h(x)=y
y=¾x +12
y=3x/4 +12
4y=3x+48
3x=48-4y
x=(48-4y)/3
replace x with h-¹
h-¹(x)=(48-4x)/3
Answer:
14/5
Step-by-step explanation:
So first i manipulated a/b= 2/5. i multiplied both sides by 5 making it 5a/b=2. Then i multiplied both sides by b making it 5a=2b. Then i substituted 2b into 5a+3b=35. Making it 2b+3b=35. then i simplified it making it 5b=35. Then i solved for b making it b=7. Then i substituted b into 5a+3b=35. So that it looked like this 5a+3*7=35. then it became 5a+21=35. Then you subtract 21 making it 5a=14. You then divide by 5 making it a=14/5
So it would be 12 minutes and $5 per 12 minutes.
