X+20+x+48=180 can someone plz answer

Answers

Answer 1

Answer:

x = 56

Step-by-step explanation:

Step 1: Write out equation

x + 20 + x + 48 = 180

Step 2: Combine like terms (x)

2x + 20 + 48 = 180

Step 3: Combine like terms (constants)

2x + 68 = 180

Step 4: Subtract 68 on both sides

2x = 112

Step 5: Divide both sides by 2

x = 56

Answer 2
X = 56 you’re welcome

if
f(x)=x^2+2x-4
and
g(x)=3x+1
find
f(g(x))=__x^2+__x+__
​

Answers

Step-by-step explanation:

f(x) = x² + 2x - 4

g(x) = 3x + 1

f(g(x)) = f(3x + 1)

f(3x + 1) = [3x + 1]² + 2[3x + 1] - 4

= 9x² + 6x + 1 + 6x + 2 - 4

= 9x² + 12x -1

The current price for gasoline is $3.049 per gallon. A customer puts 7.45 gallons in her car. How much does she pay for the gas? Round your answer to the nearest cent.

Answers

Answer:

$22.72 for gas

Step-by-step explanation:

If each gallon costs $3.049, then we multiply the cost of each gallon by 7.45

3.049 x 7.45 = 22.71505

As the question asks us to round to the nearest cent in 22.71505, we would round up.

Your answer is $22.75 for gas

An astronaut is returning to earth in a spacecraft. If the spacecraft is descending at a rate of 13.81 kilometres per minute,what will be its change in height after 5 and 1/2 minutes.Round your answer to the nearest kilometer.

Answers

Answer:

-76

Step-by-step explanation:

I give credit to the other people that said it, I am not the smart one her lol

The change in height after 5 and 1/2 minutes to the nearest kilometer will be 75.955

What is the fundamental principle of multiplication?

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

we have been given that the spacecraft is descending at a rate of 13.81 kilometres per minute, then  change in height after 5 and 1/2 minutes will be;

WE can see that the astronaut is descending 13.81 km each minute, so multiply that by 5 and a half minutes .

Then multiply 5 and 1/2 minutes by 13.81,

Speed = distance / times

Rate = 11/2 x 13.81

Rate = 75.955

Therefore, The change in height after 5 and 1/2 minutes to the nearest kilometer will be 75.955

Which statement describes g(x) as a transformation of
f(x) and identifies an equation for g(x)?
Vertical stretch followed by a translation 1 unit left, so
g(x) = f*(x + 1)).
O Vertical stretch followed by a translation 1 unit right,
so g(x) = 1 + x = 1)).
O Horizontal stretch followed by a translation 1 unit left,
so g(x) = (3x + 2).
O Horizontal stretch followed by a translation 1 unit
right, so g(x) = (4 x - 1)

Answers

Answer:

The correct option is;

Horizontal stretch followed by a translation 1 unit left  so g(x) = (3·x + 2)

Step-by-step explanation:

In geometric transformation, a dilation involves the increase in the dimension of the distances between points by a given scale factor.

Therefore, with regards to the question, a dilation can be represented by the product of the initial dimension, x, by a variable, such as an integer

A translation right is represented by an addition to the x value, while a translation left is represented by subtraction from the x value

Therefore, whereby f(x) = x + 1

An horizontal stretch of 3 will be 3 × (x + 1) = 3·x + 3

Followed by an a translation 1 unit left will be;

3·x + 3 - 1 = 3·x + 2;

Therefore;

g(x) = (3·x + 2).

x = 7 + 3y
5x + 6y = 14
Which ordered pair (x,y) is the solution to the system of equations above?

Answers

Given Equation:

x = 7 + 3y

or, x - 3y - 7 = 0 ........ (i)

5x + 6y = 14

or, 5x + 6y - 14 = 0 .........(ii)

To Find:

The value of x and y.

Solution:

By dividing eq. ii by 2, we get

5/2x + 3y - 7 = 0 ........ (iii)

By adding eq. i and eq. iii, we get

15/2x = 0

or, x = 0 ........(iv)

By putting eq.(iv) in eq. (i), we get

0 - 3y - 7 = 0

or, -3y = 7

or, y = -7/3

Answer: ( 0, -7/3 )

The value of x and y is 0 and -7/3 respectively.
