Answer:5/6=25/blank

Step-by-step explanation:so 5/6 the top is times five forget the bottom for now just think of 5 and 25

[5x5] equals 25 so you already got the top

now for the bottom since you multiply the top by five you have to do that to the bottom so that will be    [6x5] that equals 30 so you got your answer

[25/30]

Answer:

increase

Step-by-step explanation:

....................

Answer:

Percent Increase

Step-by-step explanation:

Percent Increase because if the necklace was bought for $260, and was marked up by 30%, it means it was originally a lower price, that was multiplied by 130%.

Explanation by algebra:

x + 0.30x = 260

1.3x = 260

x = 260/1.3

x = 200

The necklace was originally $200, and it was marked up by 30$, making it $260.

Answer:

It takes 5/8 minutes or 0.625 minutes to print per page.

Step-by-step explanation:

The find the singular unit value of how long it would take per page you simply divide the amount that you are trying to figure out by the total amount of time you are taking and in this case it would be 5 divided by 8 in order to solve for the amount of minutes it takes per page.

Answer:

AREA: 49.2 miles

PERIMETER: 49.2

Step-by-step explanation:

in finding the area, multiply by 4 the same because it has the same sizes, A=s⁴ or Side x side x side x side

In finding the Perimeter

you need to add 12.3 miles to four sizes or same sizes

P= 12.3 + 12.3 + 12.3 + 12.3

Answer:

infinite solution , b/c when i graphed it , it showed a line that went on & on

Step-by-step explanation:

2(4+2.5x)+7 = -3(x-5)

8+5x+7=-3x+15

15+5x=-3x+15

2x=0

Answer:

y = 5

Step-by-step explanation:

40 = 8y

divide both sides by 8, isolating y by itself:

40/8 = 8y/8

5 = y

rearrange the equation so the y is on the left side

y = 5

The answer is y = 5

We can check by plugging in y = 5 into the original equation:

40 = 8y

40 = 8(5)

40 = 40

correct

Answer:

19 oz

Step-by-step explanation:

Lauren bought 20 ounces of sliced ham, out of which she used three-fourth of the ham to make sandwiches for her friends and one fifth of the ham in an omelette. We are to find the ounces of ham that were left. So, total ounces of ham that were used = 15 + 4 = 19 ounces.

Answer:

(a) Expanded form:

[tex]((X_1 + X_1Y_1) - X_1Z_1) + ((X_2 + X_2Y_2) - X_2Z_2) + ((X_3 + X_3Y_3) - X_3Z_3) + ((X_4 + X_4Y_4) - X_4Z_4)[/tex]

(b) The value of the expression: -21

Step-by-step explanation:

Given

[tex]\sum \limit^4_{i=1}\ ((X_i+X_iY_i) - X_iZ_i)[/tex]

Solving (a): The expanded form:

This means that we substitute the values of i from 1 to 4 in the above expression.

So, the expression becomes:

[tex]((X_1 + X_1Y_1) - X_1Z_1) + ((X_2 + X_2Y_2) - X_2Z_2) + ((X_3 + X_3Y_3) - X_3Z_3) + ((X_4 + X_4Y_4) - X_4Z_4)[/tex]

Solving (b): The value of the expression

To do this, we simply substitute the given values of X1, X2....... in the expression.

This gives:

So, the expression becomes:

[tex]((0 + 0*5) - 0*0) + ((1 + 1*26) - 1*-2) + ((12 + 12*-2) - 12*3) + ((-1 + -1*25) - -1*24)[/tex]

Simplify each bracket

[tex]((0 + 0) - 0) + ((1 + 26) +2) + ((12 -24) - 36) + ((-1 -25) +24)[/tex]

[tex]0 + 29 -48 -2[/tex]

[tex]-21[/tex]

Hence, the result of the expression is -21

Answer:

[tex] \frac{a + cd}{a} [/tex]

Step-by-step explanation:

ax - cd = a

=> ax = a + cd

[tex] = > x = \frac{a + cd}{a} [/tex]

Hence,

Option A is the answer.

Answer:

A. [tex]\frac{a+cd}{a}[/tex]

Step-by-step explanation:

ax-cd=a

Add cd to both sides:

ax=a+cd

Divide both sides by a:

x=[tex]\frac{a+cd}{a}[/tex]

Answer:

The probability of spinning yellow or blue is [tex]\frac{4}{5}[/tex] or 80%.

Step-by-step explanation:

Since the circle is split evenly into 5 parts, and 4 parts are either blue or yellow, that means the probability of spinning blue or yellow is the number of blue or yellow sections divided by the total sections, which is [tex]\frac{4}{5}[/tex] or 80%.

Answer:

13+63 if I'm not wrong......

Answer:

3. X = (-4, -5), Y = (0, -3), Z = (-1, -7)

4. Refer back to my explanation.

5. a. Refer back to my explanation.

5. b. 28 units^2; please solve for the other rectangle.

5. c. No, because translation means moving the figure, not changing the shape or size.

Step-by-step explanation:

Warning in advance: the picture is very blurry when looking at the numbers on the graph so I have tried my best to decipher them.

3.

First, write down the ordered pairs for X, Y, and Z.

X = (-1, 4)

Y = (3, 6)

Z = (2, 2)

Note that horizontal movement (moving left or right) affects only the x coordinate. If you are moving to the left, you will subtract from the x coordinate. If you are moving to the right, you will add to the x coordinate.

Vertical movement (moving up or down) affects only the y coordinate. If you are moving up, you will add to the y coordinate. If you are moving down, you will subtract from the y coordinate.

Apply this concept to the ordered pairs:

Moving left = subtraction from x coordinate

Moving down = subtraction from y coordinate

X2 = (-1 - 3, 4 - 9) = (-4, -5)

Y2 = (3 - 3, 6 - 9) = (0, -3)

Z2 = (2 - 3, 2 - 9) = (-1, -7)

Your new image should have X at (-4, -5), Y at (0, -3), and Z at (-1, -7).

4.

After reading the concepts and seeing my explanation and demonstration, please try number 4 on your own. If you have any questions, feel free to ask me for help.

5. a.

The same goes for this problem since it is the same concept.

5. b.

To find the area of a rectangle, use the equation length × width, also known as l × w. In order to figure out what the length and width are equal to, count the units on the graph. JK is 7 units wide. Since this is a rectangle, ML will be the same width, 7 units. KL is 4 units long so JM will also be 4 units long. Now that we know the number of units, we can plug the numbers into the formula:

4 units × 7 units = 28 units^2

The question asks to solve for the area of each rectangle so please try the same for the rectangle you create from problem 5. a.

5. c.

The area of a figure will not change after translation because translation does not affect the figure's size or shape. If the figure is only moved, then no part of its area is changed so no, the area of a figure will not change.

Answer:

X=9

Step-by-step explanation:

2(9)-5 > 11

18-5 > 11

13>11

2x-5>11

2x-5+5>11+5 five will be cancelled five

2x>11+5

2x>16 divide 2 by 2 you get x then divide 16 by 2

x>8 this means x is greater than eight {x= 9,10,11,12.......}

Answer:

C.

Step-by-step explanation:

The response variable can be defined as those variables that are considered to be the focus of a question in research or experiment. It is also known as a dependent variable and is marked on the y-axis. The response variable is explained with the help of an explanatory variable, marked on the x-axis. The other names for response variables are y-variables or outcome variables.

In the given case, the response variable is the grade received on each assignment. The grades received by students on each assignment are the main focus of this research.

Therefore, option C is correct.

Answer:

It is not possible

Step-by-step explanation:

Required

Convert 0.8km to hours and minutes

One of the condition for a successful conversion is that: only units of the same metric can be converted.

i.e.

Meters can be converted to feet (they both measure distance)

Days can be converted to years (they both measure time)

Pounds can be converted to grams (they both measure weight)

But in the given question, you attempt to convert from distance to time.

This is not possible, because time and distance are different measurements

Answer:

A (the first answer)

Step-by-step explanation:

Answer:

3x + 2y = 11

3x + y = 11 - 2

3x + y = 9

x + y = 9/3

x + y = 3

x = 3 - y

5x - y = 14

x - y = 14/5

x - y = 2.8

x = 2.8 + y

14Answer:

3

Step-by-step explanation:

solve for y in first equation

5x-y=14

-y=14-5x

y=5x-14

substitute y value (5x-14) into 2nd equation

3x+2 (5x-14)=11

3x+10x-28=11

13x=39

x=3
