Answer:
The speed of River's mom drove for 10 miles distance is 0.234 mph.
The speed of River's mom drove for 25 miles is 10.234 mph.
Step-by-step explanation:
Given as :
The first distance cover by River's mom = 10 miles
The rate of speed = x mph
The second distance cover by river's mom = 25 miles
The rate of speed = x + 10 mph
The total driving time = 45 min
Now, According to question
So,
Now dividing by 5 on both side we get;
Solving this quadratic equation we get;
Since speed cannot be in negative hence we will consider x= 0.234
So, The speed for 10 miles distance = x = 0.234 mph
and The speed of 25 miles = x + 10 = 0.234 + 10 = 10.234 mph
Hence The speed of River's mom drove for 10 miles distance is 0.234 mph
and The speed of River's mom drove for 25 miles is 10.234 mph
159 green
If there are 14 baskets of apples and 36 apples in each basket then there are 504 apples in all (14*36=504)
Then you can take 504-225-120 (the red and the yellow) and whatever is left must be the green. That equals 159.
Hope that helps.

The value of x in the equation is 4.2.
<h3>How to calculate the value?</h3>
It should be noted that the equation given is:
12(-11x + 5) + 7 = 2 (x-9) - 451
This will be computed thus:
12(-11x + 5) + 7 = 2 (x-9) - 451
-132x + 60 + 7 = 2x - 28 - 451
Collect like terms
-132x - 2x = - 28 - 451 - 60 - 7
-130x = -546
Divide
x = 546/130
x = 4.2
The value of x in the equation is 4.2.
