Answer:
The mechanic who worked 5 hours charged $115 per hour, the one who worked 15 hours charged $120 per hour.
Step-by-step explanation:
x = rate of mechanic who worked 5 hours
y = rate of mechanic who worked 15 hours
Then
x + y = 235
5x + 15y = 2375
Just solve these 2 equations above for x and y.
x + y = 235 ⇒ x = 235 - y
Substitute into second equation to find y.
5(235 - y) + 15y = 2375
1175 - 5y + 15y = 2375
10y = 1200
y = 1200/10 = 120
x = 235 - y = 235 - 120 = 115

3.6 is your answer
The independent variable for this function is the number of items wrapped while the dependent variable is the cost to wrap the gifts. This is because the independent variable refers to the input to the function while the dependent variable is the output of the function. In this case, the function is expressed as:
C = 3 + 1(X)
where,
C = cost of wrapping the gifts
X = number of items wrapped
Answer:
TT , TW , TL , LT , LW , LL , WT , WW , WL
Step-by-step explanation:
They tell us that Maggie's fubtol team can can win (W), lose (L), or tie (T) each game, which means that it has 3 possible results and is two games, therefore the number of results would be :
Hence 2 Games will have 3² possible out comes.
3² = 9
In other words, there are a total of 9 possible results, distributed as follows:
T W L
T W L T W L T W L
TT TW TL WT WW WL LT LW LL
It means that the possible outcomes are:
TT , TW , TL , LT , LW , LL , WT , WW , WL
