Answer:
Step-by-step explanation:
a spinner with the colors orange, yellow, purple, and green.....so this spinner only has 4 spaces....and 1 of those spaces is purple...so the ratio of stopping on purple is 1/4 or 0.25
The range is the interval of y values.
Smallest y values is -9 and the highest y values is 9.
So the range is
Answer:
the solution is (-4, -3)
Step-by-step explanation:
Multiply the first equation by 2. This produces 4x + 2y = -14.
Now combine this result with the second equation:
4x + 2y = -14
-3x - 2y = 10
------------------
x = -4
Subbing -4 for x in the first equation yields 2x - 4 = -7, or 2x = -3.
Then x = -3/2, and the solution is (-4, -3)
<em>The question has missing details. However, general questions that could be asked is as follows:</em>
<em>(1) The number of miles traveled after using (say) 5 gallons</em>
<em>(2) The number of gallons used after traveling for (say) 36 miles</em>
Answer:
See Explanation
Step-by-step explanation:
Given

A linear equation is represented as:

Where
and

c, in this question represents the initial capacity of the tank.
So, the initial capacity is 120 liters
Solving (a): r = 5




<em>60 miles traveled</em>
Solving (b): s = 36


Collect like terms


Solve for r

<em>42 gallons used</em>
For this case we can make the following rule of three to solve the problem:
8 planets -------------------> 100%
6 planets -------------------> x
From here, we clear the value of x.
We have then:

Answer:
the percentage of the planets that have moons is 75%
