Step-by-step explanation:

3m=-3

m=1

Answer:

m = -1

Step-by-step explanation:

3m + 4 = 1

subtract 4 from each side of the equation:

3m + 4 - 4 = 1 - 4

3m = -3

divide both sides by 3:

3m/3 = -3/3

m = -1

Answer:

pencil: $2

marker: $0.75

eraser: $0.5

Step-by-step explanation:

Let the prices of one pencil, one marker, and one eraser be p, m, and e, respectively.

Gloria:

8p + 4m + 6e = 22         Eq. 1

Teresa:

5p + 7m + 8e = 19.25      Eq. 2

Rebecca:

5p + 5m + 4e = 15.75       Eq. 3

Subtract Eq. 3 from Eq. 2:

2m + 4e = 3.5                Eq. 4

Multiply Eq. 2 by 8 and subtract from it Eq. 1 multiplied by 5.

       40p + 56m + 64e = 154           Eq. 2 times 8

(-)     40p + 20m + 30e = 110            Eq. 1 times 5

----------------------------------------

                  36m + 34e = 44        

                  18m + 17e = 22              Eq.5

Now use Equations 4 and 5 as a system of two equations in two variables.

Multiply Eq. 4 by 18. Subtract Eq. 5 from it.

       36m + 72e = 63

(-)     36m + 34e = 44

-----------------------------

                  38e = 19

e = 19/38

e = 0.5

Now substitute e = 0.5 into Eq. 4 to fond m.

2m + 4e = 3.5

2m + 4(0.5) = 3.5

2m + 2 = 3.5

2m = 1.5

m = 0.75

Substitute e = 0.5 and m = 0.75 into Eq. 1 to find p.

8p + 4m + 6e = 22

8p + 4(0.75) + 6(0.5) = 22

8p + 3 + 3 = 22

8p = 16

p = 2

Answer:

pencil: $2

marker: $0.75

eraser: $0.5

The cost of each of the items are: cost of pencil = $2, cost of marker = $ 3 / 4  and cost of eraser = $ 1 / 2

let

the cost of pencil = x

the cost of marker = y

the cost of eraser = z

Gloria bought 8 pencils, 4 markers, and 6 erasers. Therefore,

8x + 4y + 6z = 22

Teresa spent $19.25 buying 5 pencils, 7 markers, and 8 erasers. Therefore,

5x + 7y + 8z = 19.25

Rebecca bought 5 pencils, 5 markers, and 4 erasers for $15.75. Therefore,

5x + 5y + 4z = 15.75

Let'a combine the equation

8x + 4y + 6z = 22

5x + 7y + 8z = 19.25

5x + 5y + 4z = 15.75

Therefore,

x = 2, y = 3 / 4 and z = 1 / 2

Therefore, the cost of each item are as follows;

cost of pencil = $2

cost of marker = $ 3 / 4

cost of eraser = $ 1 / 2

b) Add the answer from previous step 6 to the numerator 1. New numerator is 6 + 1 = 7

c) Write a previous answer (new numerator 7) over the denominator 6.

One and one sixth is seven sixths

Conversion a mixed number 7 3/

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(6, 6) = 6. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 6 × 6 = 36. In the next intermediate step, the fraction result cannot be further simplified by canceling.

In words - seven sixths minus forty-five sixths = minus nineteen thirds.

Step-by-step explanation:

Median = The middle number ( in terms of value )

So the first step is usually to put the set of numbers in order from least to greatest but they have already done that for us

That being said all we have to do is find the middle number

In the set, 10, 18, 21, 25, 31, 33, 36

the middle number would be 25

Answer:

1. He earned 246

82% = 0.82

Move decimal right twice

82 x 300 is 24600

Move decimal left twice

= 246

2. 25

Solve for Y (Total Diamonds)

12 = 48% × Y

12 = [tex]\frac{48}{100}[/tex] × Y

Y = 12 × [tex]\frac{100}{48}[/tex]

Y = 12 × 100 ÷ 48

Y = 25

3.80.95%

Solve for "%"

% = 34/42

% = 0.8095 (rounded)

Convert decimal to percent using percent formula:

% = 0.8095 × 100 = 80.95%

Answer:300

Step-by-step explanation:

Answer:

The answer to question 14 is (6, 5), and the answer to question 15 is D) x = -2 and y = 1.

Step-by-step explanation:

Question 14 explanation: Because each line on the graph represents a different function, that means that the point where they intersect is the answer, as the point both appear on the equations [tex]y = \frac{1}{2} x+2[/tex] and [tex]y=x-1[/tex]. Since the two equations' point of intersection is (6, 5), that means the solution to the system of equations is the point (6, 5).

Question 15 explanation: The solution to the system of equations [tex]3x+4y=-2[/tex] and [tex]2x-4y=-8[/tex] would be the x and y values that satisfy both equations. If you select the pair on selection D, you'll find that it's valid. [tex]3(-2)+4(1)=-2[/tex] ⇒ [tex]-6+4=-2[/tex] ⇒ [tex]-2 = -2[/tex], which is true, so choice D works for the first equation. [tex]2(-2)-4(1)=-8[/tex] ⇒ [tex]-4-4=-8[/tex] ⇒ [tex]-8=-8[/tex], which is also true. This means that x = -2 and y = 1 is the solution to the system of equations, making choice D the correct answer.

Answer:

j = -8/11

geometric figure it is called a line.

Step-by-step explanation:

Expand the following:

4 (6 j + 5 j + 8)

Grouping like terms, 5 j + 8 + 6 j = (5 j + 6 j) + 8:

4 (5 j + 6 j) + 8

5 j + 6 j = 11 j:

4 (11 j + 8)

4 (11 j + 8) = 4×8 + 4×11 j:

4×8 + 4×11 j

4×8 = 32:

32 + 4×11 j

4×11 = 44:
