What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

From the information given, the taxi fair is equal to the initial cost of first mile added to the result of multiplying the cost per mile for the number of miles, which is:

t=2.25+3.50x, where:

t is the b

x is the number of miles

Now, you can replace t with 44.25  and solve for x to find the miles:

44.25=2.25+3.50x

42 = 3.5x

x = 42/3.5

x = 12

Therefore, the distance from the hotel to the airport was 12 miles.

Answer 2
Answer: 44.25 = 3.50x + 2.25
44 = 3.50x
12.5714285714 = x
So, about 12.6

How many solutions does the following equation have? -25z+1+35z=10z+1 Choose 1 answer: A.No solutions B.Exactly one solution C.Infinitely many solutions

Answers

Answer:

C

Step-by-step explanation:

given

- 25z + 1 + 35z = 10z + 1 ( collect like terms on left side )

10z + 1 = 10z + 1

since both sides are the same then any value of z is a solution of the equation.

the equation has infinitely many solutions

a culture initially contains 200 bacteria . if the number of bacteria doubles every 2 hours , how many bacteria will be in the culture at the end of 12 hours ?

Answers

The population of the bacteria that doubles every 2 hours and have 200 initial population within 12 hours is 12,800. This is computed by dividing 12 hours by 2 hours, which will give us 6. This means that the bacteria doubled six times. Thus, multiplying 200 by 2 six times, this will give us 12,800.
So after every 2 hours the bacteria's numbers double (or 100% is "added") so we can simplify 12 down to 6 because we only want the number after every two hours, 400+800+1600+3200+ 6400+ 12800 = 25200 total after 12 hours

In right triangle ABC with the right angle at C, sin A= 2x + .1 and cos B = 4x - .7. Determine and state the vaule of x.

Answers

Imagine \angle A at the top of the triangle and \angle B at the bottom. (or used the attached picture for reference)

\sin A= (opposite)/(hypotenuse)

\cos B = (adjacent)/(hypotenuse)

One thing to note, however, is that the side opposite \angle A is the same side as the one adjacent to \angle B! Thus \sin A=\cos B.

Substitute these values for 2x+0.1 and 4x-0.7 and solve.
