Randy is checking to determine if the expressions 2 x + 2 + 4 x and 2 (3 x + 1) are equivalent. When x = 3, he correctly finds that both expressions have a value of 20. When x = 2, he correctly evaluates the first expression to find that 2 x + 2 + 4 x = 14.

What is the value of the second expression when x = 2, and are the two expressions equivalent?

The mass of each bag of flour is 2 kg.

In physics, mass is a quantitative measure of inertia, which is a fundamental property of all matter. In the International System of Units, a kilogram is a unit of mass (SI).

Given that the mass of each bag of rice is 1.2 kg. We can see that there are 5 and 3 bags containing rice and flour respectively. First, we have to calculate the total weight of the right side of the weight machine. Then we equate it with the total weight of the left side of the weight machine.

Let, the mass of each bag of flour be y kg.

Now,

Weight of the right side = Weight of the left side

i.e. number of rice bags × mass of rice bags = no. of flour bags × mass of flour bags

i.e. 5 × 1.2 = 3 × y

i.e. 3y = 6.0

i.e. y =6/3=2

So, the mass of each bag of flour is 2 kg.

Complete question :

Stacy has a spinner (1 - 4) and a number cube (1 - 6) after spinning and rolling the number cube she will add two number what is the probability that the sum of the numbers from the spinner and number cube will be 3 or 4

Answer:

5 /24

Step-by-step explanation:

The sample space for the sun of the outcome of the spinner and rolled number cube ;

Sample space = total possible outcomes = 6 * 4 = 24

Required outcome = sum equals 3 or 4 = 5

P(obtaining a sum of 3 or 4) = required outcome / Total possible outcomes

P(obtaining a sum of 3 or 4) = 5 /24

Step-by-step explanation:

This is because 7 times (Multiplied) by 9-4 is 35. We get here by doing 9-4=5. This problem then turns into 7(5)

Answer:

b. (4,2)

Step-by-step explanation:

step one: isolate x in the first equation

substitute x=6-y: [tex]\begin{bmatrix}2\left(6-y\right)-2y=4\end{bmatrix}[/tex]

[tex]\begin{bmatrix}12-4y=4\end{bmatrix}[/tex]

[tex]-4y=-8[/tex]

[tex]y=2[/tex]

step two: isolate y in the second equation, substitute y=2

[tex]x=6-y[/tex]

[tex]x=6-2[/tex]

[tex]x=4[/tex]

Answer:

b

Step-by-step explanation:

Given the 2 equations

3x + 3y = 18 → (2)

2x - 2y = 4 → (2)

Multiplying (1) by 2 and (2) by 3 and adding the result will eliminate the y- term

6x + 6y = 36 → (3)

6x - 6y = 12 → (4)

Add (3) and (4) term by term to eliminate y

12x + 0 = 48

12x = 48 ( divide both sides by 12 )

x = 4

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

Substituting into (1)

3(4) + 3y = 18

12 + 3y = 18 ( subtract 12 from both sides )

3y = 6 ( divide both sides by 3 )

y = 2

solution is (4, 2 ) → b

Answer:

15π cubic units

Step-by-step explanation:

the formula for the volume of a cone is:

V = (base area x height) / 3

In this case we have

(5π x 9)/3 = 15π cubic units

Answer:

235.5 Cubic Units

Step-by-step explanation:

V=1/3B*H

=1/3(π5^2)9

=1/3(3.14*25)9

=3(3.14*25)

=75*3.14=235.5 Cubic Units

Answer:

x = 71°

Step-by-step explanation:

Segments of tangents from the same external point are congruent, that is

AT = BT

Then Δ ABT is isosceles with base angles congruent , so

x = [tex]\frac{180-38}{2}[/tex] = [tex]\frac{142}{2}[/tex] = 71°

The cost of petrol the car used in October is;

Amount spent on fuel in October = £79.76

Distance sally drove in October = 560 miles

She used 1 gallon of petrol for every 34.5 miles she drove.

Thus, number of gallons of petrol she used for the month of October on the car = 560/34.5 gallons

Now, we are told that;

1 gallon = 4.55 litres

Thus; 560/34.5 gallons = (560/34.5) × 4.55/1

Quantity of petrol she used for the month in liters = 73.855 litres

Petrol costs £1.08 per liter.

Thus;

Amount spent on fuel in October = 1.08 × 73.855

Amount spent on fuel in October = £79.7634 ≈ £79.76

Answer:

(-8, -5)

Step-by-step explanation:

If (-8, 5) is reflected across the x-axis, the x-coordinate stays the same (-8), but the y coordinate becomes -5.  Hence the coordinates of the reflection are (-8, -5).

If point (-8, 5) is reflected across the x axis, the new point is (-8, -5)

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.

If point (-8, 5) is reflected across the x axis, the new point is (-8, -5)

Answer:

The angle is equal to 45°, its complementary is equal to (90-45)°=45°, and its supplementar is equal to (180-45)°=135°

Step-by-step explanation:

Let the angle be equal to x°. We know that

[tex](180 - x) = 3(90- x)[/tex]

Therefore, solving for x, we have

[tex]180 - x = 270 - 3x \\ 2x = 90 \\ x = 45[/tex]

So the angle is equal to 45°, its complementary is equal to (90-45)°=45°, and its supplementar is equal to (180-45)°=135°

The length of the missing side is 7x-5

Step-by-step explanation:

Here, we want to get the value of the missing length

Mathematically, the perimeter of a triangle can be obtained by adding the lengths of its sides

So by subtracting the sum of the lengths of the two given sides from that of the perimeter, we get the length of the third side of the triangle

mathematically, we have this as;

13x-7 -(4x + 2 + 2x-4)

13x-7 - (4x + 2x + 2-4)

= 13x-7 - (6x -2)

= 13x -7 -6x + 2

= 13x-6x -7 + 2

= 7x -5
