Answer:
2.5
Step-by-step explanation:
In this equation x is equal to 2.5. I got this answer by dividing both sides of the equation by 2, since we do the opposite operation of how the equation is set up. Have a great day! :)

Thomas has constant speeds for both running and walking. When a down-escalator is moving, Thomas can run down it in 15seconds or walk down it in
30seconds. One day, when the escalator was broken (and stationary), it took Thomas
20seconds to run down it.
How long, in seconds, would it take Thomas to walk down the broken escalator?

Tim's pay increased by 5% to £880
a fortnight.
What was his pay before the
increase?
Answer:
£838.10Step-by-step explanation:
Let the previous salary be x
Increase = 5%
New salary = £880
x + 5% = 880x*1.05 = 880x = 880/1.05x = £838.10 (rounded)Answer:
£838.10Step-by-step explanation:
let x be past payaccording to the question
[tex]x \times \frac{105}{100} = 880[/tex]
[tex]x = 880 \times \frac{100}{105} [/tex]
[tex]x = 838.10[/tex]

PLS HELP Anna buys bananas and apples. She buys 2 more apples than twice the number
of bananas. Altogether, Anna bought 14 fruits. How many apples did she buy?
(Hint use a bar model)
Your answer
Answer:
You have to put this in a bar model yourself so convert it later
She bought 10 apples
Step-by-step explanation:
3x + 2 = 14
why i did this
because she bought 2 times the amount of bananas, it should be x + 2x = 3x
then i added two because she bought two extra apples
so 3x+2 = 14
subtract 2
3x = 12
x = 4
So now we substitute x in apples
2x +2 = # of apples
8 +2 = 10
check
10 - 2 = 8
8/2 = 4
4 = # of bananas
Answer:
Anna bought 4 bananas and 10 apples.
Step-by-step explanation:
System of Equations
Let's call the following variables:
x = number of bananas Anna buys
y = number of apples Anna buys
She buys 2 more apples than twice the number of bananas, thus:
y = 2x + 2 [1]
Anna bought 14 fruits in total, thus:
x + y = 14 [2]
Substituting [1] in [2]:
x + 2x + 2 = 14
Simplifying:
3x = 12
Dividing by 3:
x = 4
Substituting in [1]:
y = 2*4+2 = 10
Anna bought 4 bananas and 10 apples.
what is the equation of the blue line
The equation of the blue line will be
y = 4x -3
The equation of the line that passes through the points (1, 1) and (2, 5) is y = 4x - 3.
We have,
To find the equation of the line that passes through the coordinates (1, 1) and (2, 5), we can use the point-slope form of the equation of a line.
The point-slope form of the equation is:
y - y1 = m(x - x1)
Where (x1, y1) represents one of the given points on the line, and m represents the slope of the line.
First, let's calculate the slope (m) using the given coordinates:
m = (y2 - y1) / (x2 - x1) = (5 - 1) / (2 - 1) = 4 / 1 = 4
Now, we can choose either of the given points and substitute its coordinates into the point-slope form. Let's use (1, 1):
y - 1 = 4(x - 1)
Simplifying the equation:
y - 1 = 4x - 4
y = 4x - 3
Therefore,
The equation of the line that passes through the points (1, 1) and (2, 5) is y = 4x - 3.

Step-by-step explanation:
Find the missing length indicated
I WILL GIVE BRAINLIEST TO CORRECT ANSWER
Answer:
The length of the missing side is: x = 15
Thus, option A) is the correct option.
Step-by-step explanation:
Let 'x' be the missing sides.
From the given triangle, it is clear that the segment cuts the sides into proportional ratios such 9 : 12 and x : 20 respectively.
Therefore,
9 : 12 = x : 20
9/12 = x/20
cross multiplication
12 × x = 20 × 9
12x = 180
divide both sides by 12
12x/12 = 180/12
x = 15
Therefore, the length of the missing side is: x = 15
Thus, option A) is the correct option.

Step-by-step explanation:
[tex]\sqrt{5}[/tex] × [tex]\sqrt{5}[/tex] × [tex]\sqrt{2}[/tex] × [tex]\sqrt{2}[/tex] = 5×2 = 10 or [tex]\sqrt{100}[/tex]
When the same square root multiply each other, they equal to the number in the square root. E.g. [tex]\sqrt{5}[/tex] × [tex]\sqrt{5}[/tex] = 5 because [tex]\sqrt{5}[/tex] × [tex]\sqrt{5}[/tex] also equals to [tex]\sqrt{25}[/tex], which is 5.

Mode ??
Median ??
Answer:
No mode
Median 7
Step-by-step explanation:
Mode: The mode is the element that occurs most in the data set. In this case, all elements occur only once, so there is no mode.
Median: Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.
Answer:
Mode: no mode
No mode because there are no repeating numbers.
Median=7
Put in order from least to greatest- 1,6,7,42,81

x2 + 2x – 15 = 0
Answer:
x = - 5, x = 3
Step-by-step explanation:
Given
x² + 2x - 15 = 0
Consider the factors of the constant term (- 15) which sum to give the coefficient of the x- term (+ 2)
The factors are + 5 and - 3 , since
5 × - 3 = - 15 and 5 - 3 = + 2, so
x² + 2x - 15 = 0
(x + 5)(x - 3) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5
x - 3 = 0 ⇒ x = 3
