Step-by-step explanation:
58x.15= 8.70
8.70+58= 66.70
Answer:
2 hours, 142 miles
Step-by-step explanation:
Given;
equation of motion of car A as;
y = 55x + 32
equation of motion of car B as;
y = 42x + 58
where;
y is distance measured in miles
x is time measured in hours
When the distance of the two cars are equal, we will have the following equation;
55x + 32 = 42x + 58
collect like terms and solve for x
55x - 42x = 58 - 32
13x = 26
x = 26 /13
x = 2 hours ( x is time measured in hours)
Now substitute in the value of x into any equation of the cars;
y = 55x + 32
y = 55 (2) + 32
y = 110 + 32
y = 142 miles ( y is distance measured in miles)
Thus, the correct option is 2 hours, 142 miles
Answer:
W = -1
Step-by-step explanation:
3W - 8 + 3W = -4 + 5W - 5
combine like terms
6W - 8 = -9 + 5W
subtract 5w on both sides
W - 8 = -9
add 8 on both sides
W = -1
