Ariel scored on 12 two-point and three-point shots. She scored 27 points in all. How many of each shot did Ariel make? Show work
suter [353]
For this, you multiply the 12 two point shots she made to see how many points she earned
12 x 2 = 24
now you will subtract the 24 from 27 to find out how many points are left
27 - 24 = 3
this means she made 12 two point shots (worth 24 points) and 1 three point shot (worth 3 points) to total up as her 27 points:)

Solve the system of equations:<br><br> -5x+y-4z=60<br> 2x+4y+3z=-12<br> 6x-3y-2x=-52
Bogdan [553]

Answer:

The answer to your question is:

x = -8; y = 1 ; z = -4

Step-by-step explanation:

Δ = \left[\begin{array}{ccc}-5&1&-4\\2&4&3\\6&-3&-2\end{array}\right]

  = 40 + 24 + 18 - (-4 + 45 - 96)

 = 82  + 55

 = 137

Δx = \left[\begin{array}{ccc}60&1&-4\\-12&4&3\\-52&-3&-2\end{array}\right]

= - 480 - 144 - 156 - ( 24 - 540 + 832)

= -780 -316

= - 1096

Δy = \left[\begin{array}{ccc}-5&1&-4\\2&4&3\\6&-3&-2\end{array}\right]

= 40 + 24 + 18 - ( - 4 + 45 - 96)

= 82 + 55

= 137

Δz = \left[\begin{array}{ccc}-5&1&60\\2&4&-12\\6&-3&-52\end{array}\right]

= 1040 - 360 - 72 - ( - 104 - 180 + 1440)

= 608 - 1156

= -548

x = -1096/ 137 = -8

y = 137 / 137 = 1

z = -548 / 137 = -4

How much material was required for each dresses of the same size if it took 5 1/2 yards for both ?
ki77a [65]

Answer:

2.75 yards

Step-by-step explanation:

If it took both (meaning 2) dresses a certain amount, half of that amount is one dress. So, we need to divide 5 1/2 by 2

*1/2 of 1 = 0.5

0.5 + 5 = 5.5

5.5 / 2 = 2.75

(2.75 also equals 2 3/4)

Use the table to write a linear function that relates y to x .
anygoal [31]

Answer:

The linear function is y = -3x + 2

Step-by-step explanation:

A linear function has the following format:

y = mx + b

In which m is the slope and b is the y-intercept(the value of y when x = 0).

In the table, we have that when x = 0, y = 2

This means that b = 2. So

y = mx + 2

Finding the slope:

We take two points, and the slope is given by the change in y divided by the change in x.

Points (0,2) and (1,-1)

Change in y: -1 - 2 = -3

Change in x: 1 - 0 = 1

Slope: m = \frac{-3}{1} = -3

So

y = -3x + 2

Figure ABCDE has vertices a(-3, 3), b(2, 3), c(5, -2), d(0, -3), and e(-3, -2). Plot the points on your own coordinates grid and
Ilya [14]
<h2>Answer:</h2>

Shown below

<h2>Step-by-step explanation:</h2>

First of all, we have the following points:

a(-3, 3) \\ \\ b(2, 3) \\ \\ c(5, -2) \\ \\ d(0, -3) \\ \\ e(-3, -2)

To plot these points, we need to graph a coordinate grid. Recall that a coordinate grid is composed of two perpendicular lines, that we call the axes and are labeled like number lines. The horizontal axis is called the x-axis while the vertical axis is called the y-axis, and these two axes intersect at a point called the origin. Next, let's plot each point as follows:

<h2>PART 1. Plot the points on your own coordinates grid and connect in alphabetical order. </h2><h2></h2>

Point a:

Let's stand at the origin and then move three units to the left and three units up. The resulting point is shown in the firs figure below.

Point b:

Let's stand at the origin and then move two units to the right and three units up. The resulting point is shown in the firs figure below.

Point c:

Let's stand at the origin and then move five units to the right and two units down. The resulting point is shown in the firs figure below.

Point d:

Let's stand at the origin and then move three units to down. The resulting point is shown in the firs figure below.

Point e:

Let's stand at the origin and then move three units to the left and two units down. The resulting point is shown in the firs figure below.

Next, let's connect connect the points in alphabetical order, so that the line are connected from a to b, from b to c, from c to d, from d to e and from e to a again. So the resulting graph is shown in the second figure. As you can see, this is an irregular pentagon.

<h2>PART 2. Decompose figure ABCDE into rectangles and triangles.</h2>

Every pentagon can be divided up into three triangles. Hence, from the third figure. the triangles are:

ΔABE

ΔBDE

ΔBCD

Since a rectangle is a quadrilateral whose angles are all right angles, then there is no chance to obtain a rectangle from ABCDE. To obtain a rectangle, we'd need other points and this is not what the problem asks.
