solve x for 7× + 3 = 31
Answer:
X = 4
Step-by-step explanation:
7x + 3 = 31
Step 1: Subtract 3 from both sides.
7x + 3 - 3 = 31 - 3
7x = 28
Step 2: Divide both sides by 7.
7x/7 = 28/7
Therefore, the answer is X = 4

w, the number of weeks, is b=w+6.
Which statement about this relationship is NOT true?
A.the number of weeks and total number of books increase together at a constant rate.
B.as the number of weeks increases by 1,the total number of books increases by 1.
C.the common difference between the number of weeks and total number of books is 6.
D.doubling the number of weeks also doubles the total number of books.
Answer:
The number of weeks and total number of books increase together at a constant rate.
As the number of weeks increases by 1, the total number of books increases by 1.
The common difference between the number of weeks and total number of books is 6.
Doubling the number of weeks also doubles the total number of books.

D) The price was increased by 140% and then decreased by 85%.
Answer:
B

Suppose that a certain movie earns $3,000,000 in ticket sales. If 60% goes to the movie and 40% goes to theatres: Movie studios will get $ of the total revenue Theatres will get $ of the total revenue
Answer: See explanation
Step-by-step explanation:
Amount earned by movie = $3,000,000.
Percentage that went to movie = 60%
Percentage that went to theater = 40%
Revenue gotten by movie studio = 60% × $3,000,000
= 0.6 × $3,000,000
= $1,800,000
Revenue gotten by theaters = 40% × $3,000,000
= 0.4 × $3,000,000
= $1,200,000
Find the constant of variation for the relation and use it to write an equation for the statement. Then solve the equation. If y varies inversely as the square of x, and 649-04-06-00-00
Complete question :
Find the constant of variation for the relation and use it to write an equation for the statement. Then solve the equation. If y varies inversely as the square of x, and y= 1/8 when x=1, find y when x=5
Answer:
k = 1/8
y = 1 / 200
Step-by-step explanation:
Let the constant of variation = k
y varies inversely as the square of x
y α 1/x²
y = k * 1/x²
y = k/x²
y = 1/8 ; x = 1
1/8 = k/1²
1/8 = k
K = 1/8
y ; when x = 5
y = (1/8 ÷ 5²)
y = 1/8 * 1/5²
y = 1/8 * 1/25
y = 1 / 200

The area of a rectangle is 42 m2, and the length is
8 m less than two times the width. Find the
dimensions of the rectangle.
Answer:
length = 14 m
width = 7 m
Step-by-step explanation:
l = length
w = width
l = 2w - 8
w(2w - 8) = 42
2w² - 8w - 42 = 0
you can factor out a 2 to work with smaller numbers:
w² - 4w - 21 = 0
(w - 7)(w + 3) = 0
w = 7
'w' cannot equal a negative so we discount it as an answer
find length:
l = 2(7) - 8
l = 14 - 8 or 6m

We can sue the pythagorean theorem to verify. 15^2+36^2 should equal the longest side squared or 39^2. If we plug in the numbers, it checks out!
Answer:
true
Step-by-step explanation:
we can use the Pythagorean theorem to verify if the sum of the squares built on the legs is equal to the square built on the hypotenuse
36^2 + 15^2 = 39^2
1296 + 225 = 1521
1521 = 1521
the equality is verified so the answer is true
