Answer:
Yes, 15 miles.
Step-by-step explanation:
You need to use proportions. For example with biking:
Using cross products:
The same is true for running:
The total distance is the sum of these two:
Step 1: Assign variable for the unknown that we need to find.
Let 'x' be the licence fee for a car that cost $9,900.
Step 2: Set up a proportion based on the given information.
Step 3: Solve for x
To get x alone we need to undo whatever is done to x. So multiply 9900 on both sides of the equation.
Simplifying fraction on both sides of the equation, we get...
Conclusion:
<u>$88.24 is the licence fee for a car that cost $9,900.</u>
Remember, you can do anything to an equation as long as you do it to both sides
and for inequalities, if you multiply or divide both sides by a negative, you have to flip the direction of the inequality sign
so
-6y+3>9-7y
add 7y to both sides
y+3>9
minus 3 both sides
y>6
Step-by-step explanation:
to know whether it is geometric progression or not, you need to find the common ratio. to find the ratio divide the (n+1)th term by n th term
so, 12/-4 = -3
also, -36/12 = -3
here u see the ratio is always same, i.e., common ratio.
thus u can say it is a geometric series with common ratio -3
There are 36 green marbles. The ratio of white to green is 5:12, and 5+12=17. 17x3=51. Multiplying the ratio by 3 gives 15:36. When added, these numbers add to 51. So, there are 15 white marbles and 36 green marbles.
