Can anyone answer these questions?

Answer:

1.1 Pull out like factors

6x+3= 3•(2x+1)

2.1 This equation has no solution

A non-zero constant never equals zero

2.2 Solve: 2x+1=0

Subtract 1 from both sides of the equation: 2x= -1

Divide both side of the equation by 2

x= -1/2= -0.500

Answer:

Mitchell's dog is 3 years old

Step-by-step explanation:

9 x 1/3 = 3

9 + 3 = 12

To solve this I just thought of the multiples of three under 12 that if added to 3 are equal to 12 to find Katie's cat age. The multiples of three under 12 are 3, 6 and 9. It couldn't be 3 and 6+3=9 so it had to be 9. So if Katie's cat is 9, you just multiply 9 by 1/3 or divide it by 3 to find Mitchell's dog age.

Answer:

625

Step-by-step explanation:

Since two slices is 250 calories, let us find how many calories is there in one.

250/2=125 (note, slash signs represents divide sign. When writing down, please write the actual sign.)

Now, we find how many calories are there in 5 pizza slices.

125x5=625

Answer:

A. -25x + 7

Step-by-step explanation:

First, to answer this question, we will combine the two sides of the equation:

(-9x + 13) + (-16x - 6)

Now, we take away the parentheses and add like terms:

-9x + 13 + -16x - 6 =

-25x + 7

So, the answer would be A. -25x + 7

Step-by-step explanation:

On a standard die, there are two numbers greater than 4, 5 and 6. 5 and 6 make up 2/6 of a die, or 1/3. So the probability of getting 5 or 6 once is 1/3 then to find the probability of doing it twice in a row, multiply 1/3 by 1/3( its the same number because there is no innate difference in the rolls). 1/3*1/3=1/9.  

Answer:

Step-by-step explanation:

45g + 25s = 485

g + s = 13

 45g + 25s = 485

-25g - 25s = -325

20g = 160

g = 8

8 + s = 13

s = 5

Answer:

(a) 1,411,200.

(b) 302,400.

(c) 100,800.

(d) 1,008,000.

Step-by-step explanation:

Permutation is the number of ways to select k items from n distinct items in a specific order.

The formula to compute the permutation or arrangement of k items is:

[tex]^{n}P_{k}=\frac{n!}{(n-k)!}[/tex]

(a)

Compute the total number of schedules as follows:

[tex]\text{Total Number of Schedules}=\ ^{8}P_{4}\times \ ^{7}P_{4}[/tex]

                                          [tex]=\frac{8!}{(8-4)!}\times \frac{7!}{(7-4)!}\\\\=\frac{8\times 7\times 6\times 5\times 4!}{4!}\times \frac{ 7\times 6\times 5\times 4\times 3!}{3!}\\\\=(8\times 7\times 6\times 5)\times (7\times 6\times 5\times 4)\\\\=1411200[/tex]

Thus, the total number of schedules are, 1,411,200.

(b)

Compute the number of schedules that includes neither sister as follows:

If neither of sister are included in the schedule then the number of players from the team are 7 and 6 respectively.

[tex]\text{Number of Schedules without the sisters}=\ ^{7}P_{4}\times \ ^{6}P_{4}[/tex]

                                                               [tex]=\frac{7!}{(7-4)!}\times \frac{6!}{(6-4)!}\\\\=\frac{ 7\times 6\times 5\times 4\times 3!}{3!}\times \frac{ 6\times 5\times 4\times 3\times 2!}{2!}\\\\=(7\times 6\times 5\times 4)\times (6\times 5\times 4\times 3)\\\\=302400[/tex]

Thus, the number of schedules that includes neither sister is 302,400.

(c)

Compute the number of schedules including both sisters and have them playing against each other as follows:

If both the sisters are playing against each other then there will be three more places to be filled in both the teams.

And the two sisters can play in any of the 4 matches.

[tex]\text{number of schedules including} \\\text{both sisters against each other}=(\ ^{7}P_{3}\times \ ^{6}P_{3})\times 4[/tex]

                                                [tex]=[\frac{7!}{(7-3)!}\times \frac{6!}{(6-3)!}]\times 4\\\\=[\frac{ 7\times 6\times 5\times 4!}{4!}\times \frac{ 6\times 5\times 4\times 3!}{3!}]\times 4\\\\=[(7\times 6\times 5)\times (6\times 5\times 4)]\times 4\\\\=100800[/tex]

Thus, the number of schedules including both sisters and have them playing against each other is 100,800.

(d)

Compute the number of schedules including both sisters as follows:

[tex]\# \text {Schedules with the Sisters}=\text{Total}\ \#\ \text{Schedules }-\ \# \text {Schedules without the Sisters}[/tex]                                             [tex]=1411200-302400\\=1108800[/tex]

Now compute the number of schedules having the sisters playing in different matches as follows:

[tex]\text{Playing in Different Matches}=\# \text {Schedules with the Sisters}-\text{Playing together}[/tex]

                                              [tex]=1108800-100800\\=1008000[/tex]

Thus, the number of schedules including both sisters, but have them playing in different matches is 1,008,000.

Answer: x=8.

Step-by-step explanation: Here are the steps to solving this proportion:

100/x=75/6.

Step 1: Cross-multiply.

100/ x = 75 /6

(100)*(6)=75*x

600=75x

Step 2: Flip the equation.

75x=600

Step 3: Divide both sides by 75.

75x

75

=

600

75

x=8

So the answer is x=8.

Answer:

85.02 feet

Step-by-step explanation:

In order to solve this we need to use Herons formula to discover the Area of the triangle and then solving the formula of the area to find the height.

Herons formula starts by calculating the semi-perimeter which is half the perimeter of the Triangle:

[tex]s=\frac{a+b+c}{2}\\ s=\frac{127+93+132}{2}\\s=176[/tex]

Now that we knwo that s= 176 we need to use the second part of the formula:

[tex]A=\sqrt{(S-A)(S-B)(S-C)} \\\\A=\sqrt{(176-127)(176-93)(176-132)}\\A=\sqrt{176(49)(83)(44)} \\A=5612.02[/tex]

So the area is 5612.02, with that we just have to solve the equation for area, which is [tex]A=\frac{B*H}{2}[/tex]

So it would be 2A*B=H

H=2*5612.02*132

H=85.03

Answer:

Divide is by 100.

The fraction that is equal to 6 can be some of the following:

[tex]\mathbf{\dfrac{6}{1} \ ; \dfrac{12}{2} \ ; \dfrac{18}{3} \ ; \ \dfrac{24}{4}\ ; \ \dfrac{36}{6} }[/tex]

A fraction usually comprises a numerator and a denominator separated by a division line.

The factors of a given number are the numbers that can be divided in such a given number without a remainder.

From the given example, we are to determine the factors of 6, so we will think about a number that can be divided by 6 without leaving any remainder.

These numbers are:

From these numbers, we can pick two factors that when divided together, we get 6 as our result and without any remainder.

i.e.

The fraction that is equal to 6 are:

[tex]\mathbf{\dfrac{6}{1} \ ; \dfrac{12}{2} \ ; \dfrac{18}{3} \ ; \ \dfrac{24}{4}\ ; \ \dfrac{36}{6} }[/tex]
