Answer:

Day 1 =8

Day 2 = 12

Day 3 = 18

Day 4 = 27

Step-by-step explanation:

Let x be how far he rode on  the first day

He rode 1.5 times how far he rode on the first day on the second day

1.5 x is how far he rode on the second day

He rode 1.5 times how far he rode on the second day on the third day

1.5(1.5 x) is how far he rode on the third day

2.25x

He rode 1.5 times how far he rode on the third day on the fourth  day

1.5(2.25x) is how far he rode on the fourth  day

3.375x

He needs to ride a total of 65 miles

day 1 + day 2 + day3 + day 4 = 65 miles

x + 1.5x + 2.25x + 3.375x = 65

Combine like terms

8.125x = 65

Divide each side by 8.125

8.125x/8.125 = 65/8.125

x=8

He needs to start with 8 miles on the first day

x=8

1.5x = 12

2.25x =18

3.375x =27

Day 1 =8

Day 2 = 12

Day 3 = 18

Day 4 = 27

The ratio of isabellas money to shanes money is 3:11. If isabella has $33, how much money do Shane and Isabella have together?
solong [7]
The ratio of Isabella’s money to Shane’s money is 3:11

Isabella has $33.   

We can make a proportion to solve for how much money Shane has.   
A proportion is two ratios that are set equal to each other.  

Let’s call Shane’s money ‘S’   

We get this proportion:   3/11 = 33/x   

If we cross multiply we get:   
(33) * (11) = (3) * (x)   

Simplifying it, we get:
363 = (3) * (x)   

Divide both sides by 3, we get:
x = 121   

However, the question asks how much money they have together. 

Isabella + Shane = Total
33 + 121 = $154   

<span>They have $154 together.</span>

Please explain. 100 / (-5) =
svp [43]
That would be -20. a negative divided by a negative number is positive, positive divided by negative is negative bc even numbers of negatives make it positive. and ofc 20 x 5 = 100, hence the ‘20’
