75c-300=25c+200​

Answers

Answer:

10

Step-by-step explanation:

75c-300=25c+200

-25c         -25c

50c-300=200

+300         +300

50c=500

c=10

Final Answer: [tex]c = 10[/tex]

Steps/Reasons/Explanation:

Question: Solve for the given variable: [tex]75c - 300 = 25c + 200[/tex].

Step 1: Add [tex]300[/tex] to both sides.

[tex]75c = 25c + 200 + 300[/tex]

Step 2: Simplify [tex]25c + 200 + 300[/tex] to [tex]25c + 500[/tex].

[tex]75c = 25c + 500[/tex]

Step 3: Subtract [tex]25c[/tex] from both sides.

[tex]75c - 25c = 500[/tex]

Step 4: Simplify [tex]75c - 25c[/tex] to [tex]50c[/tex].

[tex]50c = 500[/tex]

Step 5: Divide both sides by [tex]50[/tex].

[tex]c = \frac{500}{50}[/tex]

Step 6: Simplify [tex]\frac{500}{50}[/tex] to [tex]10[/tex].

[tex]c = 10[/tex]

determine whether x=33 is a solution of the equation below 3= x/11

Answers

Answer:

Yes, x = 33 is a solution

Step-by-step explanation:

To see if it is a solution, plug in 33 as x

3 = x/11

3 = 33/11

3 = 3

Since this is correct, x = 33 is a solution.

Given,

The value of x is 33.

[tex] \implies \: 3 = \bf\dfrac{x}{11} [/tex]

[tex] \implies \: 3 \times 11 = \bf x[/tex]

Putting the value of x ..

[tex] \implies \: 33 = 33[/tex]

Left hand side is equal to right hand side, it means that x = 33 is a solution of given equation.

John's family visited his grandmother over the weekend. the drive to her house was 2 hours at their usual speed. the trip back took 15 min longer because traffic was bad and they had to drive 5 mph slower. how many miles away is Johns's grandmother's house?

Answers

The distance to Johns's grandmother's house is 90 miles.

Speed

Speed is the ratio of total distance to total time taken, it is given by:

Speed = distance / time

Let x represent the speed that John used and d represent the distance, hence:

x = d/2

Also when taken 15 minute longer (0.25 hours):

x - 5 = d/(2 + 0.25)

x = d/2.25 + 5

Equating:

d/2 = d/2.25 + 5

d = 90 miles

The distance to Johns's grandmother's house is 90 miles.

y∝√x If y=60 when x=36 find,y when x=16

Answers

Answer:

y = 10√16) = 40

Step-by-step explanation:

This says, "y is proportional to the square root of x."  We are told that y = 60 when x = 36.  Find the formula for this function.  Then, determine what value y will take on when x = 16.

y = k√x  becomes 60 = k√36, or 60 = 6k.  Then k must be 10, and the formula is y = 10√x.

If x = 16, y = 10√16) = 40

find the first term and the common difference of an arithmetic progression in which t5=3x-y and t11=5y

t5 refers to term 5 and t11 refers to term 11

Answers

first term: 5x-5y

common difference: -x/2 + y

The common difference is d = -0.5x + y and the first term is 5x-5y

Geometric progression

The nth term of the geometric progression is expressed as:

[tex]T_n=a+(n-1)d[/tex]

where;

a is the first termr is the common  ration is the number of terms

The fifth term of the sequence is expressed as:

[tex]T_5=a+4d=3x-y[/tex]

[tex]T_{11}=a+10d=3x-y[/tex]

Take the difference of the terms:

[tex]4d-10d=3x-y-5y\\-6d=3x-6y\\d= -0.5x+y[/tex]

Get the first term:

a = 3x - y - 4(-0.5x+y)

a = 3x - y + 2x - 4y

a = 5x - 5y

Hence the common difference is d = -0.5x + y and the first term is 5x-5y
