Answer:
a × 2 means 'a' multiplied by 2
a(2) also means 'a' multiplied by 2
So both mean the same.
a × 2 means 2 times the value of variable "a".
a(2) represents a function "a" with input 2.
a × 2 means the value of variable "a" multiplied by 2. In mathematical terms, it is simply "2 times a" or "2 * a."
a(2) indicates a function notation, where "a" is a function and "2" is the input to that function.
It is not multiplication but rather a way of representing the value of the function "a" when the input is 2.
Hence, a × 2 means 2 times the value of variable "a".
a(2) represents a function "a" with input 2.

Question: If a point C is inside AVB then m AVC +_______= m AVB
m∠AVC+m∠CVB=m∠AVB. Option b is correct.
Given a figure in which point C is inside ∠AVB and ∠AVB=62°.
A geometric figure formed by two lines starting from a common point or two planes starting from a common line is called an angle. The space between these lines or planes is measured in degrees.
Knowing that a point C is between ∠AVB and ∠AVC=39° and ∠CVB=23°, then
From the figure, we can see that C is inside ∠AVB, so ∠AVB is divided into two parts, namely ∠AVC and ∠CVB
m∠AVC+m∠CVB=m∠AVB
Now substitute the values we get
39°+23°=62°
62°=62°
So both sides are equal and it's proven.
Hence, a point C is between ∠AVB and ∠AVB=62° then m∠AVC+m∠CVB=m∠AVB.

Tom wins at chess 180 times in every 250.Daisy wins three quarters of the time.Jacob wins 328 times in every 400?Work out who has the best percentage score.
Answer:
Jacob has the best percentage score of 82%
Step-by-step explanation:
Tom wins at chess 180 times in every 250
Daisy wins 3/4 of 180 times
Jacob wins 328 times in every 400
Tom's percentage score = [tex]\frac{180}{250} * 100[/tex] = 72%
Daisy wins [tex]\frac{3}{4} * 180 = 135[/tex] times
Daisy's percentage score = [tex]\frac{135}{250} * 100[/tex] = 54 %
Jacob's percentage score = [tex]\frac{328}{400} * 100[/tex] = 82%
∴ Jacob has the best percentage score.

Hey there! I'm happy to help!
The equation y=0.5x simply means that Joseph is hiking 0.5 miles every hour. This is because the x value is the independent variable or the thing you change, which in this case is the time you take hiking. The distance, the y-value, is dependent on that time.
Now, let's look at Kelly's graph. This graph isn't a grid, so we will have to eyeball some of the numbers on the graph. It appears that after 10 hours, Kelly has traveled eight miles. This is because if you go up from the 10 and meet the line and then go to the left. you will be about at the line right below the 10 on the y-axis, and if you count the lines, you will see that we are counting by 2, so it has to be eight.
So, we see that Kelly takes 10 hours to go eight miles. We know that Joseph's distance is half of his time (4 hours would be 2 miles, 6 hours would be 3 hours, etc.)
So, if we say that Joseph hikes for ten hours, he will have hiked five miles as that is half of ten. We see, though, that Kelly made it eight hours in that time, so Kelly is going faster here.

rovers,United and City are football teams
rovers scored x goals
United scored 8 goals more than rovers
City scored 3 goals less than twice the number of goals scored by rovers
the three teams scored a total of 117 goals
solve to find the value of x
Based on the information given, the value of x is 28 which means that Rovers scored 28 goals.
Number of goals scored by Rovers = x
United scored 8 goals more than rovers. This will be = x + 8
City scored 3 goals less than twice the number of goals scored by rovers. This will be: = 2[x} - 3 = 2x - 3
Since the three teams scored a total of 117 goals, this will be:
x + x + 8 + 2x - 3 = 117
Collect like terms
4x = 117 - 8 + 3
4x = 112
x = 112/4
x = 28
The value of x is 28

Alexandra's family took a road trip to the Grand Canyon. Alexandra slept for the last 48 miles of the trip. If the total length of the trip was 800 miles, what percentage of the total trip had they travelled when Alexandra fell asleep
Answer:
She fell asleep for 6% of the trip.
Step-by-step explanation:
You take 48 and divide it by 800. That gives you 0.06.
0.06 equals 6%.
Answer:
6%
Step-by-step explanation:
Divide 48 and 800 together.
48/800 = 0.06
48 is the miles she's sleeping and 800 is the total miles.
So, she was asleep only 6% of the trip.

If 5x + 3 = 23 , what does 12x - 10 equal ?
Answer:
38
Step-by-step explanation:
5x+3 = 23
5x = 23-3
x = 20/5
x = 4
12x-10 = ?
12 (4) -10
48 -10
38
The value of the expression 12x - 10 will be 38.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that 5x + 3 = 23. To calculate the value of 12x -10 first calculate the value of x.
5x+3 = 23
5x = 23-3
x = 20/5
x = 4
Calculate the value of 12x - 10.
12x-10 = ?
12x-10 = 12 (4) -10
12x-10 = 48 -10
12x-10 = 38
Therefore, the value of the expression 12x - 10 will be 38.

Find the value of x in the equation below.
48 = 6x
Answer:
x=8
Step-by-step explanation:
This is a simple one-step algebraic equation. In algebra, to find x you must isolate the variable. To do this, use the property of equality. This property states that an equation is still true if you do the same thing to both sides. For example, the equation would still be true if you added 1 to both sides.
To isolate x divide both sides by 6. This equals 48/6 = 6x/6. Which simplifies to 8=x.
