H: hours
45h + 45 = 30h + 75
15h + 45 = 75
15h = 30
h = 2 hours
45 ( 2 ) + 45 = 30 ( 2 ) + 75
90 + 45 = 60 + 75
135 = 135
Therefore the awnser is 2 hours.
Answer:
h = 16
Step-by-step explanation:
to solve this equation
we are going to take cognizance of the positive and negative sign as any misinterpretation of the sign might influence our answer wrongly. Note this
negative × negative = positive
positive × negative = negative
negative × positive = negative
positive × positive = positive
so, from the question 19 - h - h = -13
19 - h - h = -13
19 -2h = -13
collect the like terms
19 + 13 = 2h
32 = 2h
divide both sides by the coefficient of h which is 2
32/2 = 2h/2
16 = h
therefore h = 16
Answer:
19
