  • All angles in a triangle add up to 180°

Step-by-step explanation:

<u>Step 1: Set Up Equation</u>

3x + 2x + 60° = 180°

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Combine like terms:                    5x + 60 = 180
  2. Isolate <em>x </em>term:                              5x = 120
  3. Isolate <em>x</em>:                                       x = 24

Can someone please help me
cupoosta [38]

1a) so for this problem, I took what they gave you, 637.5 and divided it by .75 and got 850

so .75 * 850 = the gallons, so just take the number of hours and multiply it by 850 to get your gallons

0.25 x 850 = 212.5

1.5 x 850 = 1,275

2.5 x 850 = 2,125

1b) the unit rate is 850

1c) 5.5 x 850 = 4,675 gallons

1d) So 850 gallons can be filled in an hour, you only need 100 gallons

850/100 = 17/2 (simplified)

17 gallons/hour 60 minutes

------------------------- x ---------------------

2 gallons 1 hour

the gallons cancel out and the hours cancel out which leaves us with:

17 x 60 = 1,020 / 2 = 510

510 minutes

2) I don't know how to do two sorry
