Answer:
16, 74
Step-by-step explanation:
3x +10 + 12x +50 = 90
15x + 60 = 90
15x = 90 -60
15x = 30
x = 30/15
x = 2
3x + 10 = 3*2 +10 = 6 +10 = 16
12x + 50 = 12*2 +50 = 24 + 50 = 74
How fast the distance between them decrease is 16mph
<h3>How to calculate the speed of an object?</h3>
Given the following parameters
Speed of the hiker = 6mph
If is it 3/11 the rate of a cyclist, then the rate of the cyclist will be:
6 = 3x/11
3x = 66
x = 22mph
Distance between them = 22 - 6
Distance between them = 16mph
Hence how fast the distance between them decreases is 16mph

Answer:
√5 + π = 537766063.1 ×
Step-by-step explanation:
given data
√5 ≈ 2.2360679775
π ≈ 3.1415926535
to find out
√5 + π
solution
√5 + π = 2.2360679775 + 3.1415926535
√5 + π = 5.3776606310
√5 + π = 5.3776606310 × 
√5 + π = 537766063.1 ×
To transform a mixed number to an improper fraction, we must multiply the denominator by the large number, and add the numerator.
So for
: 
But we also put this over the denominator in the mixed number, so we get:
.
Then we do the same for
:

Then we must find a common denominator. Let's use 21 (multiply 3 and 7):


Now that we have a common denominator, we can subtract across:

Since
cannot be reduced any further, we are going to leave this as our answer.
So the answer is
.
