Cell phone Plan A costs $70 per month and comes with a free $500 phone. Cell phone Plan B costs
Agata [3.3K]

Answer:

25 Months

Step-by-step explanation:

Let's make the equations first,

Plan A: 70x   Plan B: 50x+500...

Now we make it into an equivalent equation:

70x=50x+500...

Then we solve:

70x=50x+500-50x -50x20x=500...

÷20 ÷20x=25...

To check if it's correct, we just plug it in:

70(25)=50(25)+500...

1750=1750...

What is the equation of the line that is perpendicular to y = one-fifth x + 4 and that passes through (5,–4)?
Brilliant_brown [7]

Answer:

y = -5x + 21

Step-by-step explanation:

perpendicular lines have slopes that are negative reciprocals.

The given line has a slope of 1/5, so the perpendicular line will have a slope of -5.

y = -5x + B

-4 = -5(5) + B

B = -4 + 25 = 21

y = -5x + 21

Theresa Morgan a chemist has a 10% hydrochloric acid solution and a 65% hydrochloric acid solution. How many liters of each shou
prisoha [69]

<u>ANSWER: </u>

170 liters of 10% hydrochloric acid must be mixed with 1700 liters of 65% hydrochloric acid solution to obtain 1870 liters of 60% solution.

<u>SOLUTION: </u>

First, set up a table. Fill in the unknowns with variables x and y. The table is attached below

From this, we can easily set up the two equations.  

Sum of values of two acids = Value of mixture  

0.1x + 0.65y = 1122  

For convenience, we'll multiply the entire equation by 100,

10x + 65y = 112200   ------ (1)  

Now, Sum of amounts of each acid = Amount of mixture  

x + y = 1870  ---------(2)

multiply (2) with 10 for easy calculation and derive the equation into one variable.

10x + 10y = 18700  

Subtracting equation (2) from (1),  

( + ) 10x + 65y = 112200

( − ) 10x + 10y = 18700

we get the solution as,

0 + 55y = 93500

Thus, 55y = 93500

y = 1700

Substituting y = 1700 in (2),

x + 1700 = 1870  

x  = 1870 - 1700  

x  = 170  

So, we have x = 170 and y = 1700

We can conclude that 170 liters of 10% hydrochloric acid must be mixed with 1700 liters of 65% hydrochloric acid solution  to obtain 1870 liters of 60% solution.

Can you form a right triangle with the three lengths given? Why or why not? 5 cm, 12 cm, 13 cm
nordsb [41]

Yes,  I  form a right triangle with the three lengths given, because The largest side which is 13cm can be squared  and will be set to  equal to the sum of squares of smaller two side.

<h3>What is a right-angled triangle?</h3>

A  right-angled triangle serves as the  triangle having  one of its angles equal to 90 degrees.

It should be noted that the other two angles sum up to 90 degrees., hence  I  form a right triangle with the three lengths given, because The largest side which is 13cm can be squared  and will be set to  equal to the sum of squares of smaller two side.
