Answers
(a) The value of 9 + (1/2) /4 * 48
We have:
[tex]9 + (1/2) /4 * 48[/tex]
Evaluate the quotients
[tex]9 + (1/2) /4 * 48 = 9 + 1/8 * 48[/tex]
Evaluate the products
[tex]9 + (1/2) /4 * 48 = 9 + 6[/tex]
[tex]9 + (1/2) /4 * 48 = 15[/tex]
Hence, the value of the expression 9 + (1/2) /4 * 48 is 15
(b) If x = 2.7, 5x =
The value of x is given as 2.7.
So, we have:
[tex]5x = 5 * 2.7[/tex]
[tex]5x = 13.5[/tex]
Hence, the value of 5x is 13.5
(c) Equivalent expression of 12x - 8x + 3
The expression is given as: 12x - 8x + 3
So, we have:
12x - 8x + 3 = 4x + 3
Hence, the equivalent expression of 12x - 8x + 3 is 4x + 3
(d) Equivalent expression of 3(x + 3y + 2x - y)
The expression is given as: 3(x + 3y + 2x - y)
So, we have:
3(x + 3y + 2x - y) = 3(3x + 2y)
Also, we have:
3(x + 3y + 2x - y) = 9x + 6y
Hence, the equivalent expressions are 3(3x + 2y) and 9x + 6y
(e) The value of 1/2x^3 + 5.2y when x = 2 and y = 3
We have: 1/2x^3 + 5.2y
So, the expression becomes
[tex]1/2x^3 + 5.2y = 1/2 * 2^3 + 5.2 * 3[/tex]
[tex]1/2x^3 + 5.2y = 19.6[/tex]
Hence, the value of 1/2x^3 + 5.2y is 19.6
(f) The commutative property of addition of 8 + 3m
The commutative property of addition of 8 + 3m is 3m + 8
(g) The algebraic expression for "5 times the sum of 2 and y?
The algebraic expression is 5(2 + y)
(h) The error of the student
The student's first error is in step 2: 4(2) + 4x(2)
(i) The statement that describes the expression 3 + y ÷ 2
The correct statement is (d) the sum of 3 and the quotient of y and 2
(j) The value of an expression
We have:
22 + 62 ÷ 22
Evaluate
22 + 62 ÷ 22 = 24.8
Hence, the value of the expression 22 + 62 ÷ 22 is 24.8
(k) Complete the blanks
We have: 34 + 2 ⋅ 5 = ____
Represent the blank with x
34 + 2 ⋅ 5 = x
Evaluate
44 = x
Hence, the blank is 44
(l) The algebraic property is used to rewrite 2(4y + 1) as (4y + 1)(2)?
The algebraic property is used to rewrite 2(4y + 1) as (4y + 1)(2) is the (c) commutative property of multiplication
(m) The statement that best describes the expression 4y ÷ 9
The statement is: (c) 4 times y divided by 9
(n) The expression is equal to 5p
The expression is equal to 5p is (a) p + p + p + p + p

If f(x) = x2, which equation represents function g?
A. G(x)=1/3f(x)
B. G(x)=3f(x)
C. G(x)=f(1/3x)
D. G(x)=f(3x)
Answers
Answer: B. G(x)=3f(x)
Step-by-step explanation: hope this helped :)
The equation that represents the graph of the function g(x) is g(x) = 3f(x)
How to determine the function g(x)?The equation of the function f(x) is given as:
f(x) = x^2
The function g(x) is compressed horizontally by a factor of 3, to get the function g(x)
This means that:
g(x) = kf(x)
Where k = 3.
So, we have:
g(x) = 3f(x)
Hence, the equation that represents the function g(x) is g(x) = 3f(x)

If a circle has a diameter of 7 inches, what is its circumference in terms of
Answers
Explanation: Formular for circumference is 2πr. Since the diameter of the circle is 7 inches and you need the radius, you have to divide the 7 by 2. Once you have the radius, plug it in to the formula.
r = 7/2 = 3.5
(2)(3.5)π
= 7π
The Circumferance of the circle would be 22 inches.
What is a circle?A circle is a locus of a point whose distance always remains constant from a given specific point. The general equation is -
x² + y² = r² (for circle centered at origin)
Given is a circle that has a diameter of 7 inches,
We have -
Diameter [d] = 7 inches
Then, radius [r] = 7/2 = 3.5 inches.
Circumferance = 2 x 22/7 x 3.5 = 22 inches
Therefore, the Circumferance of the circle would be 22 inches.

were 175 adult tickets sold and 103 child tickets sold. There was a total of $13796 in ticket sales. The
Jones family bought two adult tickets and two child tickets and spent a total of $184. How much does an
adult ticket cost and how much does a child ticket cost?
Answers
Answer:
Adult ticket is $60
Child ticket is $32
Step-by-step explanation:
Let x = price of adult ticket
y = price of child ticket
(1) 175x + 103y = 13796 (2) 2x + 2y = 184
x + y = 92
y = 92 - x
175x + 103(92 - x) = 13796
175x + 9476 - 103x = 13796
72x = 4320
x = 60 y = 92 - 60
