A is x=7.5 and B) is x=1
sergeinik [125]2 years ago
5 0

Step-by-step explanation:

a⟩. (4x - 1)/2 = x + 7

⇛(4x - 1)/2 = (x+7)/1

By doing cross multiplication, we get

⇛1(4x - 1) = 2(x + 7)

⇛4x - 1 = 2x + 7

⇛4x - 2x = 7-1

⇛2x = 6

⇛x = 6÷2 = 6/2

∴ x = 3 Ans.

b⟩. 3x + 2 = (2x + 13)/3

⇛(3x + 2)/1 = (2x + 13)/3

⇛3(3x + 2) = 1(2x + 13)

⇛9x + 6 = 2x + 13

⇛9x - 2x = 13-6

⇛7x = 7

⇛x = 7÷7 = 7/7

∴ x = 0 = 1 Ans.

If you have any doubt, then you can ask me in the comments.

If the total number of books checked out of the library at your high school is 14,400 and the student population is about 2400.
Whitepunk [10]

The number of books taken by each student is 6.

<h3>What is an average?</h3>

Average is defined as the ratio of the sum of the number of the data sets to the total number of the data. The average actually determines the middle value of the data.

Given that the total number of books checked out of the library at your high school is 14,400 and the student population is about 2400.

The average is calculated by dividing the sum of the total number of items by the total counts of the items.

Average = 14400 / 2400

Average = 6

Therefore, the number of books taken by each student is 6.

Find the length of the leg of the right triangle leave your answer in simplest radical form
erastova [34]

Answer:

a =12*sqrt(2)

Step-by-step explanation:

3.  The Pythagorean theorem states

a^2 + b^2 = c^2  where a  and b are the legs and c is the hypotenuse

a^2 +21^2 = 27^2

a^2 +441 =729

Subtract 441 from each side

a^2 +441-441 = 729 -441

a^2 =288

Take the square root of each side

sqrt(a^2) = sqrt(288)

sqrt(xy) = sqrt(x)sqrt(y)

a = sqrt(144)sqrt(2)

a =12*sqrt(2)

Question 1 (10 points)
Irina18 [472]

Answer:

Q1 d, Q2 c, Q3 d

Step-by-step explanation:

Q1

g(x)=-3x+1

g(x)=16 means that

-3x+1=16 subtract 1 from both sides

-3x=16-1 combine like terms and divide both sides by -3

x=-15/3=-5

Q2

g(x)=3x²+4x-1

g(2) means that x=2 so substitute

g(2)=3*2²+4*2-1=12+8-1=19

Q3

domain are the x values

range are the y values

Write the corresponding sides ad equal ratios
Marta_Voda [28]
Notice the corners; the corner on each triangle with one line is equivalent, and the same goes for the corner on each triangle with two lines, and the corner on each triangle with three lines. this is just a way to know which angles match up!

this means the answer would be:
