SIMPLE

Answer 2

Hello! :)

2(3x − 5) + 5 = 5x + 13 Simplify both sides of the equation

(2)(3x) + (2)(−5) + 5 = 5x + 13 Distribute

6x + −10 + 5 = 5x + 13

(6x) + (−10 + 5) = 5x + 13 Combine like terms

6x + −5 = 5x + 13

6x − 5 = 5x + 13

6x − 5 − 5x = 5x + 13 − 5x Subtract 5x from both sides

x − 5 = 13

x − 5 + 5 = 13 + 5 Add 5 to both sides

x = 18 (ANSWER)

The work that Yi did to find the greatest common factor of 42 and 63 is shown below. Factors of 42: 1, 2, 3, 6, 7, 14, 21, 42 Factors of 63: 1, 7, 9, 63 The greatest common factor is 7. What is Yi's error? Yi did not list all the factors of 63. Yi listed multiples for each number instead of factors. Yi did not list all the factors of 42. Yi found the least common multiple.

Answers

Answer: Yi did not list all the factors of 63

Step-by-step explanation:

Given That :

Factors of 42: 1, 2, 3, 6, 7, 14, 21, 42

Factors of 63: 1, 7, 9, 63

The greatest common factor is 7

Find the error in the calculation above :

Not all factors of 63 were listed

The surf instructor has an initial fee of $12 and charges $8 per hour for lessons, which is represented by the equation y = 8x + 12, where x is the number of hours and y is the total cost. The instructor gives 32 hours of lessons a month to Sandra and 24 hours of lessons a month to Bela. What is the total amount the instructor makes in a month?

Sandra: y = 8 (32) + 12. y = 256 + 12. y = 268. The instructor receives 268 dollars a month from Sandra.

Answers

Answer:

Step-by-step explanation:

Y=8(32)+12

Y=256+12

Y=268 (Sandra)

Y=8(24)+12

Y=192+12

Y=204 (Bela)

204+268=472

Mount McKinley is Alaska is 5910 feet higher
than Mount Rainier in Washington. Together,
their heights total 34,730 feet. How high is each
mountain?

Answers

Answer:

20,320 feet

Step-by-step explanation:

Let Mt Rainer be X.

Let Mt KcKinley be X+5,910.

So,   X + (X + 5,910) = 34,730

Combine the variables and,   2X + 5,910 = 34,730

Subtract 5,910 from both sides and,    2X = 28,820

Divide both sides by 2 and,   X = 14,410

So, Mt Rainer is 14,410 and Mt McKinley is (14,410 + 5,910) = 20,320

Answer:

Mount McKinley = 34,730

Mount Rainier = 28,820

Step-by-step explanation:

Step 1:

x + 5,910 = 34,730   Equation

Step 2:

x = 34,730 - 5,910   Subtract 5,910 on both sides

Step 3:

x = 28,820

Step 4:

28,820 + 5,910

Answer:

Mount McKinley = 34,730

Mount Rainier = 28,820

77. The yearly cost of tuition (in-state) and required fees for

attending a public two-year college full time can be esti-

mated by the linear function f(x) = 64x + 2083, where x

is the number of years after 2000 and f(x) is the total cost.

(Source: The College Board)

a. Use this function to approximate the yearly cost of

attending a two-year college in the year 2016. (Hint: Find

f(16).]

b. Use the given function to predict in what year the yearly

cost of tuition and required fees will exceed $3200. [Hint:

Let f(x) = 3200, solve for x, then round your solution

up to the next whole year.]

c. Use this function to approximate the yearly cost of

attending a two-year college in the present year. If you

attend a two-year college, is this amount greater than or

less than the amount that is currently charged by the col-

lege you attend?

Answers

Answer:

a. [tex]\$3107[/tex]

b. 17 years

c. The amount that is currently charged by the college you attend is much higher than the amount charged in two-year college in the present year.

Step-by-step explanation:

a.

[tex]f(x)=64x+2083[/tex]

Here, x is a the number of years after 2000 and f(x) is the total cost.

To approximate the yearly cost of  attending a two-year college in the year 2016,  find [tex]f(16)[/tex].

[tex]f(16)=64(16)+2083\\\\=1024+2083\\\\=\$3107[/tex]

b.

To predict in what year the yearly  cost of tuition and required fees will exceed $3200, solve [tex]f(x)=3200[/tex]

[tex]64x+2083=3200\\\\64x=3200-2083\\\\=1117\\x=\frac{1117}{64}\\\\ =17.45[/tex]

So,

x is approximately equal to 17 years.

c.

The present year is 2020.

To approximate the yearly cost of  attending a two-year college in the present year, find [tex]f(20)[/tex]

[tex]f(20)=64(20)+2083\\\\=1280+2083\\\\=\$3363[/tex]

The amount that is currently charged by the college you attend is much higher than the amount charged in two-year college in the present year.

|x-4|=6x+16 solve equation please

Answers

Step-by-step explanation:

|x-4|=6x+16 To find the absolute value :

x - 4 = 6x + 16 or x - 4 = -6x - 16 for first equation

x - 4 = 6x + 16 export like terms to the same side of the equation

-4 - 16 = 6x - x (The terms chages signs from negative to positive and from positive to negative when exported to the other sideof the equation)

-20 = 5x divide by 5

-4 = x

For the second equation

x - 4 = -6x - 16 export like terms to the same side of the equation

x + 6x = -16 + 4

7x = -12

x = 1.7 approximately

Answers

Answer:

Domain: All real numbers greater than or equal to 0 and less than or equal to 50

Range: All real numbers greater than or equal to 0 and less than or equal to 100

Step-by-step explanation

The workout is at 100% at 50 mins. Anything less would be under these two numbers.  Since the percentage of workout is on the y-axis, anything between zero and 100 can be possible. The time is on the x-axis, so anything 0 to 50 can be possible.
