Answer:

x = 5/6

Step-by-step explanation:

Cross multiply.

18(x - 2) = 3(-7)

Divide both sides by 3.

6(x - 2) = -7

Distribute the 6.

6x - 12 = -7

Add 12 to both sides.

6x = 5

Divide both sides by 6.

x = 5/6

Answer: x = 5/6

[tex]\dashrightarrow\:\:\sf \dfrac{x - 2}{3} = \dfrac{-7}{18} \\ \\ \\ [/tex]

[tex]\dashrightarrow\:\:\sf (x - 2) \times 18= -7 \times 3 \\ \\ \\ [/tex]

[tex]\dashrightarrow\:\:\sf 18x - 36 = -21 \\ \\ \\ [/tex]

[tex]\dashrightarrow\:\:\sf 18x = -21 + 36\\ \\ \\ [/tex]

[tex]\dashrightarrow\:\:\sf x = \dfrac{15}{18} \\ \\ \\ [/tex]

Answer:

There are 72 pieces of candy.

Step-by-step explanation:

Since there are 16 Reeses in all, we need to find out how many 2's can fit in 16. We can do that by either multiplying or dividing.

16 ÷ 2 = 8 or 8 × 2 = 16

So we have 8 groups of 2 Reeses, now we need to multiply the groups of Reeses by how many Snickers.

So:

8 × 7 = 56

Now we need to add the Snickers and the Reeses.

56 + 16 = 72

Answer:

72 candies

Step-by-step explanation:

To find the number of snickers, divide the 16 reese's pieces by two to get 8. For every two reese's pieces, there are seven snickers, so multiply that by seven to get 56. There are 56 snickers. Add the 56 snickers to the given 16 reese's pieces for 72 total pieces of candy. Hope this helped ^^

Answer:

B

Step-by-step explanation:

Given the 2 equations

y = 2x + 6 → (1)

y = x + 2 → (2)

Substitute y = 2x + 6 into (2)

2x + 6 = x + 2 ( subtract x from both sides )

x + 6 = 2 ( subtract 6 from both sides )

x = - 4

Substitute x = - 4 into either of the 2 equations and evaluate for y

Substituting into (2)

y = - 4 + 2 = - 2

solution is (- 4, - 2 ) → B

Answer:

No

Step-by-step explanation:

Number of pieces of pepperoni available with Pamela = 112

Number of pieces of pepperoni used in one pizza = 29

Now, number of pepperoni left after using 29 in one pizza = 112 - 29 = 83

Now, Pamela makes second pizza, so again 29 pieces of pepperoni area used.

Now, number of pepperoni left after using 29 in one pizza = 83 - 29 = 54

Now, Pamela makes third pizza, so again 29 pieces of pepperoni area used.

Now, number of pepperoni left after using 29 in one pizza = 54 - 29 = 25

To make the third pizza, another 29 pepperoni are required but only 25 are available.

Therefore, there is not enough pepperoni for making 4 more pizza.

Answer:

The acceleration is 2m/s^2

Step-by-step explanation:

Given

Variation: Direction Variation

Represent Force with F and Acceleration with A

When

[tex]F= 9N; A=3m/s^2[/tex]

Required

Find A when F =6N

The variation can be represented as:

[tex]F \alpha A[/tex]

Convert to an equation

[tex]F = kA[/tex]

Where

[tex]k = variation\ constant[/tex]

When

[tex]F= 9N; A=3m/s^2[/tex]

We have:

[tex]9N = k * 3m/s^2[/tex]

Solve or k

[tex]k = \frac{9N}{3m/s^2}[/tex]

[tex]k = 3kg[/tex]

When

[tex]F = 6N[/tex]

We have:

[tex]F = kA[/tex]

Substitute 6N for F and 3kg for k

[tex]6N = 3kg * A[/tex]

Solve for A

[tex]A = \frac{6N}{3kg}[/tex]

[tex]A = 2m/s^2[/tex]

Answer:

13

Step-by-step explanation:

The length of the line segment is 13 unit.

A line segment is a straight line with finite length, and thus, have to endpoints(points on either ends).

If the ray lies onto the considered line segment(overlapping), then it can be said belonging to the considered line segment.

(line segment has 2 fixed ends, whereas a ray has one end only, other end is not fixed)

We are given that coordinate plane shows Line A B.

We need to find the length of the line segment.

We can see that the graph has 1 unit equal to 1 cm.

Then the coordinate for Point B is (5, 13)

The length of the line segment is 13 unit.

Answer:

the coldest point would be 4 degrees.

Step-by-step explanation:

On a nuber line you would plot the point 13 and go back on the number line 9 units and you would get 4 degrees.

The temperature at its coldest point is 4° F.

Given that, one winter day, the temperature outside was 13°F. Overnight, the temperature dropped 9°F.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the temperature at its coldest point be x.

Now, x = 13 - 9

= 4° F

Therefore, the temperature at its coldest point is 4° F.

Answer:

E) -4,7 and -2,8

Step-by-step explanation:

parallel lines have same slope

x - 2y = 16

y = 1/2 x -8     slope: 1/2

E. slope = Δy / Δx = (8-7) / (-2 - -4) = 1/2

Using the slope, it is found that the line passing through points (-4,7) and (-2,8), option E, is parallel to the given line.

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

The equation of a line, in slope-intercept formula, is given by:

[tex]y = mx + b[/tex]

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

The line given is:

[tex]x - 2y = 16[/tex]

In slope-intercept formula:

[tex]2y = x - 16[/tex]

[tex]y = \frac{x}{2} - 8[/tex]

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

In this question, we want a line with an slope of 1/2.

At option E, the points are (-4,7) and (-2,8), thus, the slope is:

[tex]m = \frac{8 - 7}{-2 - (-4)} = \frac{1}{-2 + 4} = \frac{1}{2}[/tex]

Thus, the line passing through points (-4,7) and (-2,8), option E, is parallel to the given line.

Answer:

We know that angels 5 and 6 are vertical angles, and that vertical angles are equal. We also know that angles 7 is equal to angle 6, in turn meaning that angle 7 is also equal to angle 5. Now we look at angle 8. We can see that angle 8 is vertical to angle 7, meaning its also equal to angle 7. We already established before that angle 7 is equal to angle 5, so if angle 8 is equal to angle 7 which is equal to angle 5. Then angle 8 is equal to angle 5.

Answer:

~7

Step-by-step explanation:

We can estimate 27 2/3 to be 28 because it is only 1/3 away from a whole number. Similarly, we can estimate 3 9/10 to be 4 because it is only 1/10 away from a whole number. Dividing the two, we get:

(27 2/3)/(3 9/10) = ~28/4 = ~7

We can estimate that the quotient of (27 2/3)/(3 9/10) will be about 7.
