Answer:
$0.59
Step-by-step explanation:
We first find the unit rate of the large water bottles after the promotion. To do this we divide 6.3 by 3 to get 2.1. Then we want to subtract 2.69 by 2.1 to get our final answer, $0.59.
mine their average rate of travel, rounded to the nearest mile per hour.
Use the given numbers and operations to complete an equation.
Answer:
Give brainliest please! The answer is 53.2 mph
Step-by-step explanation:
Mara's family travels 239.4 miles between the hours of 9:10 a.m. to 1:40 p.m.
1:40 p.m. is 13:40.
Thus, they traveled for
13 hours 40 minutes - 9 hours 10 minutes = 4 hours 30 minutes
that is hours.
Use formula:
where
D = distance
r = rate
t = time.
In your case,
D = 239.4 miles
t = 4.5 hours
4X-(9-3X)=8X-1
In the equation, if we are to solve for x, the result would be -8.
To solve for x in the expression, the first step would be to collect like terms. Thus, we would have;
4x - (9 - 3x) = 8x - 1
4x -9 + 3x = 8x - 1
Collect similar terms
4x + 3x - 8x = -1 + 9
-x = 8
Divide both sides by -1
x = -8
So, the value of x in this equation is -8.
