PLEASE HELP ME!!! -3x + 12 < 18

Answer:

6/15 ÷ 6

Step-by-step explanation:

Martin is an after school math tutor

He noticed that 6 people still needed help on 2/5 of the time that was left

Martin wrote the expression

2/5 ÷ 6

This expression can be used to determine the number of persons who still need help

Therefore the expression that is equivalent to Martin's expression is

= 6/15 ÷ 6

Using 3 to divide both 6 and 5 will give

2/5 ÷ 6

Hence the expression which is equivalent to Martin's expression is 6/15 ÷ 6

Answer:

A 6/15 divided by 6 on edge

Answer:

the value to be written is -2

Step-by-step explanation:

The first thing we will do here is to set the divisor equals to zero

The divisor is the denominator

Thus, we have x + 2 = 0

This indicates that x = -2

The term to be written in front of the coefficients is -2

Answer:

Step-by-step explanation:

Let

Price of

Hotdogs = x

Sodas = y

Candy bar = z

Smith family

Hotdogs = 3

Sodas = 2

Candy bar = 1

Total cost = $16.50

3x + 2y + z = 16.50

Patterson family

Hotdogs = 4

Sodas = 4

Candy bar = 2

Total = $26

4x + 4y + 2z = 26

Nguyen family

Hotdogs = 2

Sodas = 1

Candy bar = 3

Total cost = $13.75

2x + y + 3z = 13.75

The equations

3x + 2y + z = 16.50 (1)

4x + 4y + 2z = 26 (2)

2x + y + 3z = 13.75 (3)

Multiply (1) by -2

-2(3x + 2y + z = 16.50)

-6x - 4y - 2z = -33

-6x - 4y - 2z = -33 (1a)

4x + 4y + 2z = 26 (2)

Add (1a) and (2)

-6x + 4x = -33 + 26

- 2x = -7

x = -7/-2

= 3.5

x = $3.5

Multiply (3) by -4

-4(2x + y + 3z = 13.75) (3)

-8x - 4y - 12z = -55 (3a)

Add (3a) and (2)

-8x - 4y - 12z = -55 (3a)

4x + 4y + 2z = 26 (2)

-8x + 4x -12z + 2z = -55 + 36

-4x - 10z = -29

Substitute the value of x into

-4x - 10z = -29

-4(3.5) - 10z = -29

-14 - 10z = -29

-10z = -29 + 14

-10z = - 15

z = -15 / - 10

= 1.5

z = $1.5

Substitute values of x and z into (1)

3x + 2y + z = 16.50

3(3.5) + 2y + 1.5 = 16.50

10.5 + 2y + 1.5 = 16.50

12 + 2y = 16.50

2y = 16.50 - 12

2y = 4.50

y = 4.50 / 2

y = $2.25

Answer:

x=63

y=27

Step-by-step explanation:

to find x

180-117=63

to find y

90-63=27

please mark brainliest if correct

Answer:

x=63, y=27

Step-by-step explanation:

x is part of a line with 117, so you would do 180-117 to find x. Then you do 90-63 to find y, which is 27.

Answer:

y = 5x + 8

Step-by-step explanation:

Recall that if two lines are perpendicular, their slopes are negative reciprocals of one another.  Thus, given y = (-1/5)x + 9, the slope of any perpendicular is

           -1

m = --------- = 5

        (-1/5)

Starting out with the slope-intercept equation y = mx + b, we get:

-2 = 5(-2) + C, or C = 8

Thus, the desired equation is

y = 5x + 8

The equation of the line that is perpendicular to the given line is y=5x+8.

Given that, the equation of line y=(-1/5)x+9 and passes through the point (-2,-2).

The slope formula is used to calculate the inclination or steepness of a line. It finds application in determining the slope of any line by finding the ratio of the change in the y-axis to the change in the x-axis.

If m is the slope of a line, then the slope of a line perpendicular to it is -1/m.

Now, slope =-1/5

-1/m = 5

Put m=5 and the point (-2, -2) in y=mx+c and simplify

That is, -2=5(-2)+c

⇒c=8

Substitute m=5 and c=8 in y=mx+c, we get y=5x+8

Therefore, the equation of the line that is perpendicular to the given line is y=5x+8.

Answer:

x = 3

Step-by-step explanation:

Step 1: Subtract 3x from both sides.

6x + 5 − 3x = 3x + 14 − 3x

3x + 5 = 14

Step 2: Subtract 5 from both sides.

3x + 5 − 5 = 14 − 5

3x = 9

Step 3: Divide both sides by 3.

[tex]\frac{3x}{3} = \frac{9}{3}[/tex]

x = 3

Hope it helps!!

The solution of the linear equation with a single variable 6x + 5 = 3x + 14 will be 3.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The equation is given below.

6x + 5 = 3x + 14

Simplify the equation, then we have

6x + 5 = 3x + 14

6x - 3x = 14 - 5

3x = 9

x = 3

The solution of the linear equation with a single variable 6x + 5 = 3x + 14 will be 3.

Answer:

3.33hours

Step-by-step explanation:

Where the number of hours = h

the prices of stock A at 9am was $12.18 since then the price has been increasing at the rate of $0.06 each hour.

The Algebraic expression =

$12.18 + $0.06 × h

12.18 + 0.06h

At noon the price of stock B was $12.68. It begins to descrease at the rate of $0.09 per hour.

$12.68 - $0.09×h

12.68 - 0.09h

If the 2 rates continue in how many hours will the prices of the two stocks be the same?

Stock A = Stock B

12.18 + 0.06h = 12.68 - 0.09h

Collect like terms

0.06h + 0.09h = 12.68 - 12.18

0.15h = 0.5

h = 0.5/0.15

h = 3.3333333333 hours

h = 3.33hours

Answer:

vertex B' is at (1, 1)

Step-by-step explanation:

Let us revise the rules of translation of a point

Let us use the rules to solve our question

∵ Vertex A = (-5, 2)

∵ Vertex A' = (2, -2)

→ The coordinates of the two points changed which means the

  quadrilateral is translated horizontally and vertically

∵ The x-coordinate of A = -5

∵ The x-coordinate of A' = 2

→ Which means it moves to the right, so use the first rule above

∴ the rule of translation is T (x, y) → (x + h, y)

∴ x → x + h

∵ x = -5 and x + h = 2

∴ -5 + h = 2

→ Add 5 to both sides

∴ -5 + 5 + h = 2 + 5

∴ h = 7

∴ The quadrilateral is translated 7 units right

∵ The y-coordinate of A = 2

∵ The y-coordinate of A' = -2

→ Which means it moves down, so use the 4th rule above

∴ the rule of translation is T (x, y) → (x, y - k)

∴ y → y - k

∵ y = 2 and y - k = -2

∴ 2 - k = -2

→ Add K to both sides

∴ 2 - k + k = -2 + k

∴ 2 = -2 + k

→ Add 2 to both sides

∴ 2 + 2 = -2 + 2 + k

∴ 4 = k

∴ The quadrilateral is translated 4 units down

→ Let us find B'

∵ T (x, y) → (x + h, y - k) is the rule of translation

∵ B = (-6, 5)

∵ h = 7 and k = 4

∴ B' = (-6 + 7, 5 - 4)

∴ B' = (1, 1)

∴ vertex B' is at (1, 1)

Quadrilateral ABCD is translated 7 units right and 4 units down. If vertex B is at (-6, 5), then vertex B′ is at (1, 1)
