Answer:
x = 60
Step-by-step explanation:
The value of x is 60
firstly, what we have is an equilateral triangle
For an equilateral triangle, the measure of the angle is 60
Now, looking at one of the angle at the base, we can see that the measure of angle x is an alternate angle to one of the angles at the base

3x – 4y = 2; 6x – 8y = 1 .
How many solutions PLEASE
Answers
Answer:
No solution
Step-by-step explanation:
3x - 4y = 2
6x - 8y =1
Multiply the first equation by -2 so you can eliminate the x's.
-2(3x-4y =2)
6x - 8y = 1
-6x + 8y = 2
6x - 8y = 1
Add the equations so they cancel.

This is an incredibly beautiful problem! It is solved mostly by algebra. r = 1 and the height will therefore be 2
Equations
l^2 + r^2 = l^2
l is the slant height.
Solution
SA = π * l * r + π r² = π(1 + √5) Divide both sides by π
Find l
l * r + r^2 = 1 + √5
l^2 = r^2 + h^2
l^2 = r^2 + (2r)^2
l^2 = 5r^2
l = √5 * r
Now go back to this equation to find r
l * r + r^2 = 1 + √5 Substitute the value for l
√5 r * r + r^2 = 1 + √5 On the left pull out r^2
r^2 (1 + √5) = 1 + √5 Divide by 1 + √5
r^2 = 1 Take the square root on both sides
sqrt(r^2) = sqrt(1)
r =1
Therefore h = 2

Table 1 and table 3 are represent linear functions of x.
What is a linear function?A linear function is a function which forms a straight line in a graph. It is generally a polynomial function whose degree is utmost 1 or 0. Although the linear functions are also represented in terms of calculus as well as linear algebra.
Given are four tables, we need to find that which of them shows linear functions of x,
Linear functions will have the ratios of x and y coordinates, constant.
In table 1 :-
x/y = -1/2
-2/4 = -1/2
-3/6 = -1/2
Since the x and y coordinates are constant, therefore, the function is linear.
In table 2 :-
x/y = 1/1 = 1
2/4 = 1/2
3/9 = 1/3
Since the x and y coordinates are not constant, therefore, the function is not linear.
In table 3 :-
x/y = 1/5
2/10 = 1/5
3/15 = 1/5
Since the x and y coordinates are constant, therefore, the function is linear.
In table 4 :-
x/y = 1/1 = 1
2/8 = 1/4
3/27 = 1/9
Since the x and y coordinates are not constant, therefore, the function is not linear.
Hence, table 1 and table 3 are represent linear functions of x.

A seed company planted a floral mosaic of a national flag. The perimeter of the
rectangular planting area is 420 feet. The length of the area is 110 feet longer
than the width.
a.) Write a system of equations to relate the
length and width of the planting area.
b.) Use the system of equations to
determine the length and width of
the planting area.
Answers
9514 1404 393
Answer:
a) 2(L+W)=420; L-W=110
b) length: 160 ft; width: 50 ft
Step-by-step explanation:
The formula for the perimeter (P) in terms of length (L) and width (W) is ...
P = 2(L+W)
We can use this as one of the equations. The other will relate the length and width according to their difference:
L -110 = W
Substituting the given perimeter in the above equation, our system of equations is ...
420 = 2(L+W)L-110 = WSubstituting for W in the first equation gives ...
420 = 2(L +(L -110))
210 = 2L -110
320 = 2L
160 = L
160 -110 = W = 50
The planting area is 160 feet long by 50 feet wide.

Comment on the question
Most national flags have a length/width ratio of 1.5 or 2. The flags of Vatican City and Switzerland are square (1.0). The longest flag is that of Qatar, with an aspect ratio of width:length = 11:28, about 2.545. The "national flag" described here has an aspect ratio of width:length = 5:16, or 3.2. Apparently, it is not to scale, or not from Earth. (The US flag aspect ratio is 1.9.)

Aisha wants to paint the four walls of her living room.
Each wall is 2.4 m high and 3.7 m long.
One wall has a door of 2 m by 0.7 m.
Tins of paint cost £12 per 1.5 L tin.
Each litre of paint can cover 8 m2 of wall.
There is an offer of: Buy 2 tins get the 3rd at half price.
How much will Aisha pay to paint her living room?
Answers
9514 1404 393
Answer:
£30
Step-by-step explanation:
The total area of the four walls is ...
A = 4 × LW
A = 4 × (2.4 m)(3.7 m) = 35.52 m²
Subtracting the area of the door, we find the painted area to be ...
35.52 m² -(2 m)(0.7 m) = 34.12 m²
Painting this area will require ...
(34.12 m²)/(8 m²/L × 1.5 L/tin) = 2.8433... tins
Aisha will need to buy 3 tins of paint, for which she pays 2.5 times the price of 1 tin:
2.5 × £12 = £30 . . . . Aisha's cost to paint her living room
£25 or £20.10
Step-by-step explanation:
calculate the area to be painted:
2.1x4.5= 9.45m^2 for each wall
x4= 37.8m^2
area of door= 1.8x0.9= 1.62m^2
subtract the area of the door from the wall area
37.8-1.62= 36.18m^2 to be painted
divide the area by the area that 1L of paint can cover
16.18/12= 3.015 L needed
if 1.5L= £10 then, 3L= £20. she needs 2 cans + an extra 0.015 L- so another can (3 cans total) add price up.
£30- but buy 2 get 3rd 1/2 price, so take £5 off. price is £25
or
calculate price for 0.015L
1.5=£10
divide both sides by 100
0.015= £ 0.10
if 1.5L= £10 then, 3L= £20. she needs 2 cans + an extra 0.015 L
£20+£0.10= £20.10

Given
<UVS = 5x + 38
<UTS = 12x - 28
Since the sum of opposite angle of a quadrilateral is 180 degrees, hence;
5x + 38 + 12x - 28 = 180
Collect like terms
5x + 12x - 28 + 38 = 180
17x + 10 = 180
17x = 180-1-
17x = 170
x = 170/17
x = 10
hence the value of x is 10

All numbers on numerator and denominator;

Can someone please explain slope in a way that might make sense.
Answers
The slope of an equation or graph is the rate of change.
In order to find slope, we use the formula m=rise/run or m=y2-y1/x2-x1
“m” is equal to the slope
“rise” or “y2-y1” is the difference (subtraction) of the two y coordinates
“run” or “x2-x1” is the difference (subtraction) of the two x coordinates
Remember, the points we are using for this example are (4, 1) and (-2, 7)
m = y2-y1/x2-x1
m = 7-1/-2-4
1 and 7 are your y coordinates so you plug them in an find the difference (subtraction)
4 and -2 are your x coordinates so you plug them in an find the difference (subtraction)
It doesn’t matter whether you do “m=7-1/-2-4” or “m=1-7/4-(-2)” both will have the same answer
The only thing you can’t do is something like “m=7-1/4-(-2)” or “m=1-7/-2-4”
The bottom can’t be solved in the opposite way of how it was solved on top and vice versa of that makes sense
Also, keep in mind that if you see two negatives as in the “m=1-7/4-(-2)” example, you turn it into an addition symbol
Like this:
“m=1-7/4+2)”
Because two negatives are equal to a positive
m = y2-y1/x2-x1
m = 7-1/-2-4
m = 6/-6
m = 6/-6
m = -1
Remember that a negative divided by a positive is always a negative so it doesn’t matter where you place the negative sign
For example, if your slope was 2/-5, that would be the same as -2/5
And when you divide two negatives, it always equals to a positive
For example -2/-5 would simplify to 2/5
I hope that helped and made sense :)
