We are dealing with an equilateral triangle which has 3 equal sides.
length of a side = 3 ft
Since the three sides of an equilateral triangle are equal and we are given two sides to have lengths of 3x - 9 and 23 - 5x , it means that;
3x - 9 = 23 - 5x
Rearranging this gives;
3x + 5x = 23 + 9
8x = 32
x = 32/8
x = 4
putting 4 for x in 3x - 9, we have;
3(4) - 9 = 3 ft
Thus,
length of a side = 3 ft

Solve
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
Write a situation to represent the equation

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]

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
Find the one in the middle- 7
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?

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:
[tex]\sqrt{5}[/tex] × [tex]\sqrt{5}[/tex] × [tex]\sqrt{2}[/tex] × [tex]\sqrt{2}[/tex] = 5×2 = 10 or [tex]\sqrt{100}[/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.

David and his 2 children are going to the zoo.
The administration price is
Adult:£60
Children:£67
FAMILY DISCOUND CARD GIVES
1/5 off adults price
60% off child price
Work out the total price David pays after using his discount card.
Answer:
£92.40
Step-by-step explanation:
Discount price for David =1/5 of 60
= 1/5 × 60/1
= £12 (5 multiplied by 12 is 60)
Price for one child = £67
Price for 2 children= £67 × 2
= 134
Therefore discount price for the children,
134 × 60/100
= 134 × 6/10
= 134 × 3/5
= 26.8 × 3
= 80.4
= £80.40
Therefore total Price David pays,
£80.40 + £12
= £92.40

Find the equation of the line: which passes through (1,-7) and is perpendicular to (-4,6) and (5,-3)
Answer:
-9 6 that is because the line has to be perpenducular to the other line
Step-by-step explanation:
Slope of line between points (-4, 6) and (5, -3)
=> Rise / Run
=> [6 - (-3)] / [(-4) - 5]
= 9 / (-9)
= -1.
Thus slope of perpendicular line
= -1 / (-1) = 1.
We have y = x + c.
When x = 1, y = -7.
=> (-7) = (1) + c, c = -8.
Hence y = x - 8.
