What’s the answer to this

Answer:

distributive property

Answer:

associative property

Step-by-step explanation:

The associative property states that you can reorder or regroup numbers and still get the same answer.  In this example, we are regrouping the numbers (parenthesis around different numbers)

Answer:

j= -0.4

Step-by-step explanation:

multiply both sides by 60

=45j(+12)=30-12

take the 12 ti the right hand side and the sign changes

= -45j=18 then divide by 45 on both sides

j= -2/5

j= -0.4

Answer:

6/95

Step-by-step explanation:

First, let's find the total # of outcomes. There are 8+6+4+2 = 20 marbles in the bag. We have 20 options for the first draw, and 19 for the second. 20*19 = 380 total possible outcomes.

Now, let's fin the successful outcomes. There are 4 red and 6 blue marbles, so 4 for the firs tpick and 6 for the second pick. 4*6 = 24 successful outcomes. To find probability, we do successful outcomes/total outcomes, and in this case, that is 24/380, or 6/95. Hope that helps!

Step-by-step explanation:

Step 1:  Add 13x to both sides

[tex]x^2 + 13x = -13x + 13x - 4[/tex]

[tex]x^2 + 13x = -4[/tex]

Step 2:  Add 4 to both sides

[tex]x^2 + 13x + 4 = -4 + 4[/tex]

[tex]x^2 + 13x + 4[/tex]

Step 3:  Use Quadratic Formula

[tex]x = \frac{ -b \pm \sqrt{ b^2 - 4ac } }{2a}[/tex]

[tex]x = \frac{ -(13) \pm \sqrt{ 13^2 - 4(1)(4)} } { 2(1)}[/tex]

[tex]x = \frac{-13 \pm \sqrt{153}}{2}[/tex]

[tex]x = \frac{-13\pm3\sqrt{17} }{2}[/tex]

Answer:  [tex]x = \frac{-13\pm3\sqrt{17} }{2}[/tex]

Answer:

-0.3 and - 12.7

The actual solution is -

Answer:

X=-2.45

Step-by-step explanation:you have to combine the x's which gives you -11x-2=25 so then you have to add two to 25 and it leaves you with -11x=27 and then you just divide 27 by -11 and x is -2.45

Answer:

x = -5

Step-by-step explanation:

start with factoring

-x^2 - 10x - 25 = 0 (i moved 25 to the left side)

then you can multiply the entire equation by -1 to get rid of the negative sign

x^2 + 10x + 25 = 0

now 5x5 = 25 and 5+5 = 10.

so (x^2 + 5x + 5x + 25) = 0

x(x+5) 5(x+5) = 0

(x+5)(x+5) = 0

(x+5)^2 = 0

so x = -5

Answer:

45 feet

Step-by-step explanation:

To find the hypotenuse of that triangle, you would have to do 81-28, because that's the portion that snapped. That equals 53.

Then, we can apply the Pythagorean theorem: a^2+28^2=53^2

a^2=2025

a=45

Therefore, 45 feet

Answer:

a = 4

Step-by-step explanation:

In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we took away 8 only from one side then the equation would change so it's an important rule to keep in mind when solving equations, that you need to keep both sides of the equation the same.

4 (2 + a) = 24

→ Expand the brackets

8 + 4a = 24

→ Minus 8 from both sides to isolate 4a

4a = 16

→ Divide both sides by 4 to isolate a and therefore find the value of a

a = 4

→ We can substitute a = 4 back into 4 (2 + a) = 24 to see if we have the correct solution, if we end with the same number on both sides then a =4 is correct.

4 (2 + a) = 24

4 (2 + 4) = 24

4 × 6 = 24

24 = 24

So a = 4 is correct

4 (2

Answer:

The equation of the axis of symmetry for this parabola is x = 0.

Step-by-step explanation:

For parabola's, it's axis of symmetry always goes through the vertex of the parabola. In other words, the axis of symmetry is vertical line that goes through the x-coordinate of the vertex.

Now, the vertex is given as (0,3) which is at x = 0, y = 3.

Thus, the vertical line that goes through the x-coordinate of the vertex will be x = 0

Thus, the equation of the axis of symmetry for this parabola is x = 0.

Answer:

Cylinder Q has a greater volume

Step-by-step explanation:

For this question we need to utilise the volume of a cylinder which is

→ Volume of a cylinder = π × r² × h

Let's substitute in the values and then do the analysis

Cylinder P

→ Volume of a cylinder = π × r² × h

⇒ Substitute in the values

→ Volume of a cylinder = π × 4.25² × 14

⇒ Simplify

→ Volume of a cylinder = 794.430242277

The volume of cylinder P is 794.430242277

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

Cylinder Q

→ Volume of a cylinder = π × r² × h

⇒ Substitute in the values

→ Volume of a cylinder = π × 7² × 8.5

⇒ Simplify

→ Volume of a cylinder = 1308.47334022

The volume of cylinder Q is 1308.47334022

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

We can see that cylinder Q has a greater volume

Answer:

Correct option: D

Step-by-step explanation:

First we need to find the rate of the series, and we can do that subtracting one term by the term before:

Second term minus first: 13/10 - 1/2 = 13/10 - 5/10 = 8/10 = 4/5

Third term minus second: 21/10 - 13/10 = 8/10 = 4/5

So the series increases by 4/5 for every term, and the first term is 1/2

We also need to find the number of terms of this series.

The last term is 93/10, so we have that:

1/2 + (4/5)*k = 93/10

(4/5)k = 88/10

k = 11

The index of the summatory should go from 0 to 11.

So the correct option is D

Answer:

7

Step-by-step explanation:

The mean is the average of the numbers. Add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

7 + 14 + 7 + 16 + 16 = 60

60 / 5 = 12

Answer:

Coca cola bottles = 6

Milk bottles = 14

Jellybeans = 10

Step-by-step explanation:

We are given that a bag of sweets contains coca cola bottles, milk bottles and jellybeans.

The ratio of these sweet bottles is given as,

3:7:5

It is known that there are 6 coca cola bottles.

We are asked to find the quantity of milk bottles and jellybeans.

Coca cola bottles:

Since the ration is 3:7:5

3 parts of coca cola bottle = 6

1 part of coca cola bottle = 6/3 = 2

Milk bottles:

So 7 parts of milk bottle = 7*2 = 14

Jellybeans:

So 5 parts of milk bottle = 5*2 = 10

Therefore,

Coca cola bottles = 6

Milk bottles = 14

Jellybeans = 10

Verification:

6:14:10

Simply the ratio by dividing it with 2

3:7:5

Which reduces to the given ratio hence results are correct.

The value of b is -1

Answer:

28 more people to reach 450

Step-by-step explanation:

450/7≈65(the total number of money the need divided by ticket price to see how many total people they need)

37*7=259 (the people they have already gotten times ticket price to find how much more they need)

450-259= 191 (what they need altogether miinus what they already have)

191/7≈28 (how much more money they need divided by ticket price, 28 is more ticket they need to sell)
