Answer:

<em><u>Answer is below</u></em>

Step-by-step explanation:

<u><em>Simplify both sides of the equation.</em></u>

3(2x+5)=3x+4x\\(3)(2x)+(3)(5)=3x+4x\\(Distribute)\\6x+15=3x+4x\\6x+15=(3x+4x)\\(CLT)\\6x+15=7x\\6x+15=7x\\

<u><em>Subtract 7x from both sides.</em></u>

6x+15-7x=7x-7x\\-x+15=0\\

<u><em>Divide both sides by -1.</em></u>

-x/-1=-15/-1\\x=15

the average person drinks 1 pint of milk a day . At this rate, how many gallons will a person drink in a leap year
Nezavi [6.7K]
Leap years have 366 days, and there are 8 pints per gallon. So we divide the 366 days by the 8 pints per 1 gallon. We end up getting:
45.75 gallons in 1 leap year.

PLEASE GIVE ME AN ANSWER QUICKLY! Hiroshi spends 30 minutes on history homework , 60 minutes on English homework, and x minutes
natka813 [3]

Answer:

A

Step-by-step explanation:

  • He spends:
  • 30 mins on History
  • 60 mins on English
  • x mins on math
  • so the total time he spends is (TotalTime)minutes=(30+60+x)minutes
  • one fourth of this is his math time, since x is math time, then we have \frac{1}{4}(TotalTime)minutes=(x)minutes
  • But we know what totaltime in minutes is so \frac{1}{4}(30+60+x)minutes=(x)minutes
  • or simply: \frac{1}{4}(30+60+x)=x
