8) Shawna had $20 to spend on six pencils. After buying them she had
$2. How much did each pencil cost?

Answers

Answer: They were $6 each

Step-by-step explanation:

20-2=18

18/3=$6

Answer:

Step-by-step explanation:

Since we know that there was $2 that she didn't use, we can subtract that from $20 to get $18 that was used (20 - 2 = 18)

We then divide 18 by 6 because she bought six pencils (18/6 = 3)

Each pencil costs $3

Hope this helps!

Edit: I saw your comment how you need to do the equation so here it is

(20 - 2)/6 = 3 (I could be wrong, but using my explanation and the information you gave, this would be correct)

A system of linear equations includes the line that is created by the equation y = 0.5 x minus 1 and the line through the points (3, 1) and (–5, –7), shown below. What is the solution to the system of equations?

Answers

Answer:

The solution to the system of equations is x = 4 and y = 2.

Step-by-step explanation:

From statement we know that the first line is [tex]y = 0.5\cdot x[/tex]. The second line is determined by knowing two distinct points and solving the resulting system of equations by definition of the equation of the line:

[tex](x_{1},y_{1}) = (3,1)[/tex] and [tex](x_{2}, y_{2}) =(-5,-7)[/tex]

[tex]3\cdot m + b = 1[/tex] (1)

[tex]-5\cdot m + b = -7[/tex] (2)

The solution of the system of equations is:

[tex]m = 1[/tex], [tex]b = -2[/tex]

The second line is represented by [tex]y = x-2[/tex]. And the resulting system of equations is:

[tex]0.5\cdot x -y = 0[/tex] (3)

[tex]x-y = 2[/tex] (4)

The soltuion to the system of equations is:

[tex]x = 4[/tex], [tex]y = 2[/tex]

The solution to the system of equations is x = 4 and y = 2.

Graph the linear function that passes through the point (1. -9) and has a slope of -3. (just give me points :)

What is the zero of the function?

Answers

The points of the linear function on the graph would be (-2,0), (0,-6), (-3,3) and (1,-9).
The slope intercept form is y=-3x-6.
And the zero of the function is x=-2.

To find the graph, use the slope intercept equation and the points.
The roots or “Zeros” are the x values where the graph intersects the x-axis. To find the roots (zeros), replace y with 0 and solve for X.

A family is on a road trip. The speed limit during the first 145 miles of the trip is 60 mph, and the speed

limit during the last 190 miles is 65 mph. How many miles per hour over the speed limits must they drive in

order to arrive at their destination in 5 hours?

Answers

Answer:

first 145 mile 7mph

next 190miles 2mph

Step-by-step explanation:

total distance to be covered = 145+190=335miles

time = distance/speed

first 145 miles

time = 145/60 =2.41hr

next 190 miles

time = 190/65 = 2.92hr

Total time = 2.41+2.92 = 5.33hr

but we need to cover the entire distance in 5hr

Speed = distance /time

= 335/5 = 67mph

That means in first 145 mile the speed over the speed limit will be 67-60= 7mph

similarly in the next 190miles speed over speed limit will be 65 - 67 = 2mph.

Answers

Answer:

Step-by-step explanation:

Let width of the parking space = x meters

Since, parking space is 6 meters longer than the width,

Length of the parking space = (x + 6) meters

Area of the parking space = Length × Width

= x(x + 6)

Area of the parking space is less than 40 square meters.

Therefore, inequality representing the area of the parking will be,

x(x + 6) < 40

x² + 6x < 40

x² + 6x - 40 < 0

x² + 10x - 4x - 40 < 0

x(x + 10) - 4(x + 10) < 0

(x - 4)(x + 10) < 0

-10 < x < 4

For -10 < x ≤ 0, width of the paring will be negative.

Therefore, possible values of x will be in the interval,

0 < x < 4

Or 0 < width < 4

Length of the parking space will be,

6 < Length < 10

There are 50 cars on display at a car show. Of these,18 were manufactured before 1945. What percent of the cars were manufactured before 1945?

Answers

Answer:

36%

Step-by-step explanation:

The total number of cars is 50 and 18 were manufactured before 1945

Let's set up a fraction

18/50

A percent should be out of 100 so let's change the denominator to 100

18/50 (times 2 for 18 and 50 to get 50 to 100)= 36/100

36/100 is 36%

divide 18 by 50 because the fraction line is like a division symbol

that equals 0.36, times 100 to get 36%

Answers

Answer:

128

Step-by-step explanation:

There is a common difference between consecutive terms, that is

11 - 2 = 20 - 11 = 9

This indicates the sequence is arithmetic with n th term

[tex]t_{n}[/tex] = t₁ + (n - 1)d

where t₁ is the first term and d the common difference

Here t₁ = 2 and d = 9 , thus

t₁₅ = 2 + (14 × 9) = 2 + 126 = 128

Answers

Answer:

Angle F is 50° because their side lengths are different but the angle measurements did not change. All triangles add up to 180 degrees and a right angle is 90 and it gives you the other angle measurement. So you would do 40 plus 90 which would get you 130. To find the last angle you would do 180 minus 130 which is 50. Angle F is 50 degrees.
