William solved the equation 5 + 14a = 9a - 5, but he is not sure he solved it correctly. His work is shown below. Did he solve it correctly? If not, on which step did William make his first mistake?
Step 1: 5+ 4a = 94 - 5
Step 2. 5+ 5a=.5
Step 3: 5a = 0
Step 4: a=0
A.Step 3

C. Step 1
D. Step 4
E. William did not make a mistake.
Answer:
Yes it looks correct but that is just me
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
This is the correct solution.
5 + 14a = 9a -5
14a - 9a = -5 -5
5a = -10
a=-10/5 = -2
Therefore, a = -2
Consider the pattern:2; 5; 8; 11; ......... Write down the next two terms
Describe the rule in your own words
Write down the general rule algebraically. Use your rule to work out the position of term 119 in the pattern.
Answer:
356
Step-by-step explanation:
Next two terms = 11 + 3 = 14
14 + 3
The rule is that the number is increasing by 3 in each term.
n th term = 2 + (n - 1)3
119 term
2 + (119 - 1)3
2 + (118)3
2 + 354

Given f(x) = 3x2 − 48 and g(x) = x − 4, identify (f/g)(x).
a. 3x + 12, x ≠ 4
b. 3x − 12, x ≠ 4
c. x − 4, x ≠ 4
d. x + 4, x ≠ 4
The choose a. 3x+12
[tex]( \frac{f}{g} )(x) = \frac{3 {x}^{2} - 48 }{x - 4} = \frac{3( {x}^{2} - 16) }{x - 4} \\ \\ = \frac{3(x - 4)(x + 4)}{x -4} \\ \\ = 3(x + 4) \\ = 3x + 12[/tex]

After evaluating (f/g)(x) is equal to 3x + 12.
The correct option is (A).
What is a Function?An expression, rule, or law in mathematics that establishes the relationship between an independent variable and a dependent variable (the dependent variable). Functions may be found everywhere in mathematics, and they are essential for building physical connections in the sciences. The modern definition of function was first proposed in 1837 by the German mathematician Peter Dirichlet: A variable y is said to be a function of the independent variable x if there is a correlation between them such that a rule determines a particular value of y whenever a numerical value is assigned to x.
As per the given data:
We are given two functions, f(x) and g(x)
f(x) = 3x² - 48
g(x) = x - 4
We have to find out (f/g)(x).
For finding out [tex]\frac{f}{g}(x)[/tex]:
= f(x) / g(x)
= [tex]\frac{3x^2 - 48}{x - 4}[/tex]
= [tex]\frac{3(x^2 - 16)}{x-4}[/tex] {a² - b² = (a + b)(a - b)}
= [tex]\frac{3(x-4)(x+4)}{(x-4)}[/tex]
= 3(x+4)
= 3x + 12
Hence, after evaluating (f/g)(x) is equal to 3x + 12.

Alex bought a fan for Rs 1,400, then spent Rs 200 on its repairs and sold it for Rs 1,800. Find his gain percent.
Answer:
11.1%
Step-by-step explanation:
Total spent=1400+200
=Rs.1600
Sold price=1800
Gain=1800-1600
=Rs.200
Gain %=gain/cost*100
=200/1800*100
=11.1%

Calvin owns a toy store. He can spend at most $200 on restocking cars and dolls. A doll costs $6.50, and a car costs $8.00. Let x represent the number of cars, and let y represent the number of dolls. Identify an inequality for the number of toys he can buy. Then identify the number of dolls Calvin can buy if he buys 10 cars.
8x + 6.50y ≤ 200; no more than 19 dolls
8x + 6.50y ≤ 200; no more than 18 dolls
6.50x + 8y ≤ 200; no more than 19 dolls
6.50x + 8y ≤ 200; no more than 18 dolls
The required inequality expression is 8x + 6.50y ≤ 200
Maximum amount he can spend = $200
Cost of doll, = $6.50
Cost of car = $ 8.00
Mathematically, the maximum amount he can spend on restocking is cars and doll is :
(Cost of cars × number of cars) + (cost of doll × number of dolls) ≤ maximum amount
8x + 6.50y ≤ 200
Hence, the required inequality expression is : 8x + 6.50y ≤ 200

Answer:
1.32 = (1 * 100) + (3 * 1/101) + (2 * 1/102)
1.32 = (1 * 1) + (3 * 1/10) + (2 * 1/100)
1.32 = 1 + 3/10 + 2/100

= 12a - 10 + 2a + 2 =
= 12a + 2a - 10 + 2 = 14a - 8
Answer:
14a-8
Step-by-step explanation:
A perimeter is the sum of the length of each side. So we can find the perimeter by adding: (a+1)+(a+1)+(6a-5)+(6a-5).
Combine like terms to get: 14a+2-10 = 14a-8.
Without knowing what a is, the perimeter is 14a-8.

-0.3 is rational. 3.141441444... is not rational.
Step-by-step explanation:
Rational number is either terminal or repeating.
-0.3 is a terminal decimal because it stops. You can write the decimal without "..."
3.141441444... is an irrational number because it is not a terminal decimal (since it has "...") and it is not repeating since the digits on the right side of the decimal are not repeating. They are changing.
3.14141414... would be repeating since "14" is repeated endlessly. However 3.141441444 is "14" then "144" and adding an additional 4 to this pattern with every iteration.

Answer:
Step-by-step explanation:
Since the perimeter is 46, and opposite sides of a rectangle are equal, we know that
(x+2)+(x+2)+(2x+3)+(2x+3)=46
Combine like terms to get: 6x+10=46
Subtract 10 from both sides to get: 6x=36
Divide both sides by 6 to get: x=6.

Please help me rq!! i need help
Answer:
x = 2
Step-by-step explanation:
The volume (V) of a cuboid is calculated as
V = lbh ( l is length, b is breadth, h is height )
Here l = 10x , b = [tex]\frac{7}{4}[/tex] , h = 2 , then
V = 10x × [tex]\frac{7}{4}[/tex] × 2 = 70 , that is
20x × [tex]\frac{7}{4}[/tex] = 70
5x × 7 = 70
35x = 70 ( divide both sides by 35 )
x = 2
Answer:
[tex]x=2[/tex]
Step-by-step explanation:
Since L × W × H = V, we get
[tex]10x*\frac{7}{4}*2=70\\10x*\frac{7}{4}=35\\10x=20\\x=2[/tex]

Answer:
Step-by-step explanation:
r = 3
angle = 50
Formula: Length = (angle/360) * 2 pi * r
Length = (50/360) * 2 * 3.14 * 3
Length = 0.13889 * 2 * 3.14 * 3
Length = 0.13899 * 6 * 3.14

If the digits A, B and C are added, the sum is the two-digit number AB as shown. What is the value of C?
A
B
+ C
______
AB
Answer:
C=9
Step-by-step explanation:
If A, B, and C are all single digits the mimimum sum for AB would be 10 as it is a two-digit number (or 11 if you do not consider 0 a digit)
AB-(A+B)=C
10-(1+0)=9 or 11-(1+1)=9
therefore C=9
