Answers

Answer 1

Answer:

x=5

Step-by-step explanation:

If 4x=20 then all we need to do is to divide both sides by 4 and we get x=5. Also, if replace x with 5 within any of the equations it works.

Hope this helps!

Answer 2

The solution is: The value of x is: x=5

Here, we have,

given that,

the expression is: 4x - 8 = 12

we get,

4x - 8 = 12

or, 4x - 8 + 8 = 12 + 8

or, 4x = 20

now, we have,

If 4x=20 then all we need to do is to divide both sides by 4 and we get x=5.

i.e. 4x/4  = 20/4

or, x = 5

Also, if replace x with 5 within any of the equations it works.

Hence, The solution is: The value of x is: x=5

Step-by-step explanation:

[tex]f(n)=2n+1\\\\g(n)=3n\\\\f(n)+g(n)=?\\\\\longrightarrow (2n+1)\longleftarrow\\\\+\longrightarrow (3n)\longleftarrow\\\\f(n)+g(n)=2n+1+3n\\\\=(2n+3n)+1\\\\=(2+3)n+1\\\\=5n+1\longleftarrow \\\\\dagger[/tex]

Answer:

[tex]\boxed {\tt f(n)+g(n)=5n+1}[/tex]

Step-by-step explanation:

We want to find f(n) + g(n) . Basically, we have to find the sum of f(n) and g(n).

[tex]f(n)+g(n)[/tex]

We know that:

[tex]f(n)=2n+1\\g(n)=3n[/tex]

Therefore, we can substitute 2n+1 in for f(n) and 3n in for g(n)

[tex](2n+1)+(3n)[/tex]

Combine like terms. The terms 3n and 2n both have a "n" so they can be combined.

[tex](2n+3n)+(1)[/tex]

[tex](5n)+1[/tex]

[tex]5n+1[/tex]

f(n)+g(n) is equal to 5n+1

Gavin likes biking. This week his goal is to bike about 65 total miles over four days. Each day he wants to ride 1.5 times as far as he rode the day before. How far should he ride on each of the four days. Write the expressions for the distance Gavin needs to bike each day. Then relate these expressions to create an equation that represents Gavin's situation.

Answers

Step-by-step explanation:

let the first-day ride be x

Then the second-day ride will be =1.5 x

The third-day ride will be=1.5(1.5x)      

The Fourth-day ride will be=1.5*1.5(1.5x)  

hence for the four days the distance covered is

65=x+1.5x+1.5*1.5x+1.5*1.5*1.5x

65=x+1.5x+2.25x+3.375x

65=8.125x

divide both sides by 8.125 we have

x=65/8.125

x=8mile

the first-day ride be x=8miles

the second-day ride will be =1.5 x =1.5*8= 12miles

The third-day ride will be=1.5(1.5x) = 18miles

The Fourth-day ride will be=1.5*1.5(1.5x) = 27miles

Answers

Answer:

57°

Step-by-step explanation:

A triangle's angles should all add up to 180°

So you have to add up the other two given angles, so in this case it is 60° + 63°, which equals 123°. Then you subtract 123 ° from 180°, giving you the answer of 57°.

Answer:

it's 57

Step-by-step explanation:

the 3 angles add up to 180 so add the 2 angles together to get 123 and then subtract that from 180

3x-12 = 4x+5

Subtract 3x from each side

3x-12 -3x = 4x+5-3x

-12 = x+5

Subtract 5 from each side

-12 -5 = x+5-5

-17 = x

Answer:

-17

Step-by-step explanation:

The two angles that are shown are *corresponding angles* which means they lie in the same spot, just on two different parallel lines. They are congruent angles. Therefore, you should set up an equation to solve for x. Since the two angles are congruent, you should set the expressions equal to each other. 3x-12=4x+5.

HOPEFULLY IM RIGHT!!

Have A Nice Day!!!!

:)))

Answer:
Anthony received $320 for his birthday last year.

Explanation:
What we know:
- this year, Anthony got $150
- 150=half the amount he got last year-10

We can create an equation with this information:

Let x be equal to the amount of money Anthony received last year.
150=1/2x-10

And now we solve the equation and isolate x.

150=1/2x-10
Add 10 to both sides
150+10=1/2x-10+10
160=1/2x
Divide both sides by 1/2
160/ 1/2=1/2x / 1/2
160/ 1/2=x
Dividing by a fraction is the same as multiplying its flip
160*2=x
320=x

Did you know that the selection process actually starts months before the presentation of the awards in late February? First, in January, nomination ballots are sent to members of the Academy of Motion Picture Arts and Sciences. For most award categories, five nomination are allowed. The Academy's philosophy is that only people who work in a particular part of the motion picture industry are qualified to make nominations for an award that relates to that part of the industry. So, for example, only directors can nominate their fellow directors. The Academy believes that people in the same field can make better decisions about who is best qualified for an award. Next, members return their secret nomination ballots. Protecting the secrecy of the members' ballots is an important rule behind the selection process. Then, a company called PricewaterhouseCoopers determines the nomination results. Shortly after that, at the end of January, the nomination results are announced. Early in February, final ballots are mailed to members of the Academy. Then, members vote and return their ballots to PricewaterhouseCoopers. Next, the company determines the final results, but they are kept a strict secret. Finally, the winners are revealed when their names are read from the famous envelopes opened at the Awards presentation in late February. the tense anticipation about who the winners are is over at last!
