Answer:
65; 117; 143.
Step-by-step explanation:
1. if the ratio is 5/9/11 and the perimeter is a+b+c=325, then it is possible to write (for the perimeter):
5x+9x+11x=325;
2. to calculate the value of 'x':
x=13;
3. the required sides are:
5x=65; 9x=117; 11x=143.

Esther works for a marketing company. She earns $12 per hour, and she gets a $50 travel allowance every month. Which linear equation could be used to find her monthly pay rate?
Pls help! Write an equation of the line that passes through the points (1, 2) and (4, 8)
Answer (assuming it can be in slope-intercept form):
[tex]y =2x[/tex]
Step-by-step explanation:
1) First, find the slope of the line. Use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of the given points into the formula and solve:
[tex]m = \frac{(8)-(2)}{(4)-(1)} \\m = \frac{8-2}{4-1} \\m = \frac{6}{3} \\m = 2[/tex]
So, the slope is 2.
2) Now, use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] to write the equation of the line in point-slope form. Substitute real values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex].
Since [tex]m[/tex] represents the slope, substitute 2 in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects, choose one of the given points (it doesn't matter which one, the results will equal the same thing) and substitute its x and y values into the formula as well. (I chose (1,2), as seen below.) Then, isolate y to put the equation in slope-intercept form ([tex]y = mx + b[/tex] format) and find the following answer:
[tex]y-(2) = 2 (x-(1))\\y-2 = 2(x-1)\\y -2 = 2x-2\\y = 2x+0\\y = 2x[/tex]

Distribute and Combine Like Terms. 2(x + 7) - 2x
Answer:
14
Step-by-step explanation:
You just multiply 2 to (x + 7) which gets you 2x + 14 and then subtract 2x from 2x seeing as they are like terms and you end up with 14.

A square room has a tiled floor with 225 square tiles. How many tiles are along an edge of the room?
Tiled floor with 225 square tiles means the area of the square room is 225.
Formula needed: A = (side)^2 or in short
A = s^2.
We need to find s.
225 = r^2
sqrt{225} = sqrt{r^2}
15 = r
There are 15 tiles are along an edge of the room.

Find the value of x.
What theorems would/could you use to find x?
Thank you in advance
Answer:
a. Linear pair theorem
b. x = 40
Step-by-step explanation:
a. x° and (4x - 20)° are angles on a straight line, so, they are a linear pair. Therefore, we would apply the linear pair theorem, which says the sum of a linear pair gives us 180°.
b. x° + (4x - 20)° = 180° (linear pair theorem)
Solve for x
x + 4x - 20 = 180
5x - 20 + 20 = 180 + 20
5x = 200
5x/5 = 200/5
x = 40

A chef is going to use a mixture of two brands of Italian dressing. The first brand contains 6% vinegar, and the second brand contains 11% vinegar. The chef
wants to make 200 milliliters of a dressing that is 9% vinegar. How much of each brand should she use?
Answer:
The chef will use 120 milliliters of 11% vinegar, and 80 milliliters of 6% vinegar.
Step-by-step explanation:
Since a chef is going to use a mixture of two brands of Italian dressing, and the first brand contains 6% vinegar, and the second brand contains 11% vinegar, and the chef wants to make 200 milliliters of a dressing that is 9% vinegar, to determine how much of each brand should she use the following calculation must be performed:
100 x 0.11 + 0 x 0.06 = 11
90 x 0.11 + 10 x 0.06 = 10.5
80 x 0.11 + 20 x 0.06 = 10
70 x 0.11 + 30 x 0.06 = 9.5
60 x 0.11 + 40 x 0.06 = 9
200 x 0.6 = 120
200 x 0.4 = 80
Thus, the chef will use 120 milliliters of 11% vinegar, and 80 milliliters of 6% vinegar.

A company uses this formula to work out the cost, £A, of a taxi ride.
A = 5 + 1.9m + b
£5 is a fixed charge
m is the number of miles travelled
£b is a charge for booking online
a) Harry books a taxi online and travels 12 miles.
He pays £29.48 altogether.
How much is the charge for booking online?
b) If Sue books online and travels 20 miles, what will be
Answer:
£b = £1.68
A = £44.68
Step-by-step explanation:
Given:
A = 5 + 1.9m + b
Where,
A = total cost
m = number of miles travelled
£b = charge for booking online
£5 = fixed charge
A. Harry
A = £29.48
m = 12 miles
£b = ?
A = 5 + 1.9m + b
29.48 = 5 + 1.9(12) + b
29.48 = 5 + 22.8 + b
29.48 = 27.8 + b
29.48 - 27.8 = b
b = 1.68
£b = £1.68
b) If Sue books online and travels 20 miles, what will be
A = 5 + 1.9m + b
= 5 + 1.9(20) + 1.68
= 5 + 38 + 1.68
= 44.68
A = £44.68

Answer:
1
0.8
0.4
Step-by-step explanation:
y = 5x
Substituting '5':
5 = 5x
x = 5/5
x = 1
Substituting 4:
4 = 5x
x = 4/5
x = 0.8
Substituting 2:
2 = 5x
x = 2/5
x = 0.4
Answer:
1) x = 1
2) x = 4/5
3) x = 2/5
Step-by-step explanation:
1) 5= 5x
x = 1
2) 4 = 5x
x = 4/5
3) 2 = 5x
x = 2/5
