The width of the figure below is 5 units. The perimeter of the figure is 18 units. What is the length of the figure in units?
Talja [164]
The perimeter is all sides length added together. You can make an equation:5+5+x+x where x is the length.
5+5=10    18-10=8     There is two sides so you do eight divided by two
The length is 4

Answer:

a. earned: $292.50

b. total: $2,092.50

Step-by-step explanation:

A = 1800 [1 + (0.065 * 2.5)] = 2092.5

A = $2,092.50

To find the amount is earned, subtract the total with how much to started with

2,092 - 1,800 = 292.50

9 apples and 9 bananas cost £2.43 altogether. The total cost of 2 apples and 3 bananas is £0.69. Calculate the cost of an apple
vekshin1
Answer: 0.27£

Explanation:

9 apples + 9 bananas = 2.43
9(apple + banana) = 2.43
Apple + banana = 2.43/9
Apple + banana = 0.27£

Therefore, the cost of an apple AND a banana is 0.27£

Part 1: The equation of the line is y=2x+1

Part 2: The equation of the line in slope intercept form is y=-3x-1

Explanation:

Part 1: It is given that the point A is (1,3) and the line B is y=2 x-2

To determine the line passing through the point A and parallel to line B, let us first determine the slope and y-intercept.

From the equation of line B, the slope is m=2

Substituting the point (1,3) and m=2 in slope intercept form y=mx+b, we have,

3=2(1)+b

3=2+b

1=b

Thus, the y-intercept is b=1

Let us substitute the values m=2 and b=1 in the slope intercept form y=mx+b, we get,

y=2x+1

Thus, the equation of the line passing though point A and parallel to line B is y=2x+1

Part 2: The given two coordinates are (-1,2) and (1,-4)

To determine the equation of line in slope intercept form, first we shall find the slope and y-intercept.

From the graph, we can see that the line touches the y-axis at -1.

Hence, the y-intercept is b=-1

The formula for slope is m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Substituting the coordinates (-1,2) and (1,-4), we have,

m=\frac{-4-2}{1+1} =\frac{-6}{2} =-3

Thus, the slope is m=-3

Substituting the values b=-1 and m=-3 in the slope intercept formula y=mx+b, we get,

y=-3x-1

Thus, the equation of the line in slope intercept form is y=-3x-1

PLS HELP IF YOU WANT
Nastasia [14]

Answer:45 * t = 2.5 * (1-t)...the equation will have one solution.

Step-by-step explanation:

For this case, the first thing you should know is:

d: v * t

Where,

d: distance

v: speed

t: time

To go to school by bus we have:

d = 45 * t

To return from school we have:

d = 2.5 * (1-t)

how the distance is the same:45 * t = 2.5 * (1-t)
