Answer: 35 minutes
Step-by-step explanation:
84 liters divided by 2.4 liters per minute
84/2.4=35 minutes
Those are vertical angles meaning that they are of equal measure. set the 2 measures equal and solve for x
3x - 25 = 6x - 80
55 = 3x
x = 18 1/3 - use this number to plug back in to calculate the actual angle measures
Remove all the brackets
3(7 + 2x) + 3 = 3(5 + x) − 9(x + 1)
21 + 6x + 3 = 15 + 3x - 9x - 9 Collect like terms.
24 + 6x = 6 - 6x Add 6x to both sides.
24 + 6x + 6x = 6 Subtract 24 from both sides
12x = 6 - 24
12x = - 18 Divide by 12
x = - 18 /12
x = - 1.5
Check
3(7 + 2*(-1.5)) + 3 = ? 3(5 + -(1.5) - 9(-1.5 + 1)
3(7 - 3) + 3 =? 3(3.5) - 9*(-1/2)
3*4 + 3 =? 10.5 + 4.5
12 + 3 =? 15 And it checks.
Answer:
103
Step-by-step explanation:
the line is 180 degree angle also know as a straight angle if you take the 40 and the 33 away from 180 you are left with 103 and that is angle a
