Answer:
250 minutes of calling will cost same using both plans.
$53
Step-by-step explanation:
Please consider the complete question.
A phone company offers two monthly plans. Plan A costs $23 plus an additional $0.12 for each minute of calls. Plan B costs $18 plus an additional $0.14 of each minute of calls. For what amount of calling do the two plans cost the same? What is the cost when the two plans cost the same?
Let x represent the number of call minutes.
The total cost of calling for x minutes using plan A would be cost of x minutes plus fixed charge that is 
.
The total cost of calling for x minutes using plan B would be cost of x minutes plus fixed charge that is 
.
To find the number of minutes for which both plans will have same cost, we will equate total cost of x minutes for both plans and solve for x.
Therefore, calling for 250 minutes will cost same using both plans.
Upon substituting in expression , we will get:
Therefore, the cost will be $53, when the two plans cost the same.
This is the answer i supposed fot
Answer:
Terms:
<em>5, 2x, 4, 3x</em>
Coefficients:
<em>2 in 2x, and 3 in 3x</em>
Constants:
<em>5 and 4</em>
Factors:
<em>5, 2x, and 4</em>
Step-by-step explanation:
For terms, all of them are terms because they are all in the expression.
For coefficients, coefficients are ones that have a variable (think of it as a <em>copilot</em> kind of thing).
For factors, factors are terms that are multiplied together together to get a <em>product</em> (the answer).
For constants, these are terms that stand alone, by themselves. They are not attached to variables.
The answer is <em>13x + 20, </em>too, just in case you needed that.
Have a great day and hope this helps!
Answer:
Step-by-step explanation:
First, isolate the variables onto one side of the equation.
2x + 3 = x - 4
(subtract x)
x + 3 = -4
Then, remove any remaining numbers.
(subtract 3)
x = -7
I hope this helps!
Answer:
3/-1
Step-by-step explanation:
The slope is 3/-1 (Rise 3 on the y axis, run to the negatives by 1 on the x axis)
To find the slope of two points, use the formula of y2-y1/x2-x1 (For example, with this equation it would be 10-4/10-12)
I'm not sure what it means to interpret the slope, but hopefully this helped you!
