Answer: [tex]x=6[/tex]

Subtract 2x from both sides

[tex]8x-72-2x=2x-36-2x\\6x-72=-36[/tex]

Add 72 to both sides

[tex]6x-72+72=-36+72\\6x=36[/tex]

Divide both sides by 6

[tex]6x/6=36/6\\x=6[/tex]

Answer:

x=6

Step-by-step explanation:

first thing first you always need to get x alone and since you have an X on both side we need to move one of them to the same side as the other one.

8x-72=2x-36

add 72 on both sides ( the opposite of subtracting is adding)

8x=2x-36+72  

8x=2x+36

then we subtract 2x on both sides to get X alone

8x-2x=36

6x=36

then we divide 36 by 6 to get our answer for x

X= 6

and that's your answer, hope this helped

Answer:

I got 1/2

Step-by-step explanation:

Answer:

I think its 90 but im not sure.

Step-by-step explanation:

Final answer:

To find the total amount won by Pip and Sara, a ratio problem was solved by establishing an equation from the given ratio 7:3 and the fact that Pip gets £36 more than Sara, resulting in a total amount of £90.

Explanation:

The question involves solving a problem based on a ratio and determining the total amount of money shared by Pip and Sara. The ratio in which Pip and Sara share the money is 7:3, and since Pip gets £36 more than Sara, we can set up equations to find the individual and total amounts.

Let's denote Sara's share as S, hence Pip's share will be S + £36.

According to the ratio given, Pip's share to Sara's share is 7 to 3, so we can write the equation:

7S = 3(S + 36)

7S = 3S + 108

4S = 108

S = 27

So Pip's share is £27 + £36 = £63.

Adding both shares, the total amount is £63 + £27 = £90.

Therefore, Pip and Sara got £90 altogether.

Answer:

$346.00

Step-by-step explanation:

We know that the price to take a plane to the Island of Mysteries is $600 and the price to take a boat is $254.

To find how much money they will save if they were to take a boat, you would subtract the cost of the boat ride from the plane ride to find the difference.

$600 - $254 = $346.00

Due to the pedalfer by the formation of the acid at the time when atmospheric and volcanic gases mix with water.

Pedalfer should be comprise of the  aluminum and iron oxides. It should be considered as the subdivision of the order of zonal soil that contains the wide range of soils where sesquioxides increase with respect to the silica at the time of forming the soil. Also it should be arise when the area is humid.

Answer:

x=−1 y=4

Step-by-step explanation:

Let's solve your system by substitution.

2x−5y=−22; x+7y=27

Rewrite equations:

x+7y=27;2x−5y=−22

Step: Solve x+7y=27for x:

x+7y=27

x+7y+−7y=27+−7y(Add -7y to both sides)

x=−7y+27

Step: Substitute−7y+27 for x in 2x−5y=−22:

2x−5y=−22

2(−7y+27)−5y=−22

−19y+54=−22(Simplify both sides of the equation)

−19y+54+−54=−22+−54(Add -54 to both sides)

−19y=−76

−19y

−19

=

−76

−19

(Divide both sides by -19)

y=4

Step: Substitute 4 for y in x=−7y+27:

x=−7y+27

x=(−7)(4)+27

x=−1(Simplify both sides of the equation)

Answer:

a = 3/2 b​

Step-by-step explanation:

7a - 2b =5a + b​

Subtract 5a from each side

7a-5a - 2b =5a-5a + b

2a -2b = b

Add 2b to each side

2a-2b+2b = b+2b

2a = 3b

Divide each side by 2

2a/2 = 3b/2

a = 3/2 b​

Final answer:

The probability that the first two names chosen will both be girls from a hat that contains the names of nine boys and six girls is 1/7.

Explanation:

The question involves determining the probability of selecting two girls' names from a hat that contains the names of nine boys and six girls. We are dealing with a situation of probability without replacement, which means that once a name is drawn, it is not put back into the hat.

To calculate the probability of the first name drawn being a girl, we have 6 girls out of the total 15 students, which gives us a probability of 6/15. If a girl's name is drawn first, there will then be 5 girls' names left and 14 names total. So, the probability of the second name drawn being a girl as well is then 5/14.

To find the overall probability of both events happening, we multiply the two probabilities together: (6/15)
x (5/14) = 30/210 = 1/7. Therefore, the probability that the first two names chosen will both be girls is 1/7.

Answer:

limit does not exist

Step-by-step explanation:

From the left: f(x) = x + 10 (for x < 8), as x --> 8, f(x) --> 18

From the right: f(x) = 10 - x (for x >= 8), as x --> 8, f(x) --> 2

Since the limits on either side do not converge to the same point, the limit does not exist

we have been given an expression [tex]\frac{\frac{2}{3}}{-4}-\left(\frac{1}{6}-\frac{8}{6}\right)[/tex]. We are asked to simplify our given expression.

Using quotient rule [tex]\frac{\frac{a}{b}}{c}=\frac{a}{bc}[/tex], we will get:

[tex]\frac{2}{3\cdot -4}-\left(\frac{1}{6}-\frac{8}{6}\right)[/tex]

[tex]\frac{2}{-12}-\left(\frac{1}{6}-\frac{8}{6}\right)[/tex]

Now, we will combine like terms:

[tex]\frac{2}{-12}-\left(\frac{1-8}{6}\right)[/tex]

[tex]\frac{2}{-12}-\left(\frac{-7}{6}\right)[/tex]

[tex]-\frac{2}{12}+\frac{7}{6}[/tex]

[tex]-\frac{1}{6}+\frac{7}{6}[/tex]

Let us combine like terms:

[tex]\frac{-1+7}{6}[/tex]

[tex]\frac{6}{6}=1[/tex]

Therefore, our expression simplifies to 1.

Answer:

A

Step-by-step explanation:

We have the system of equations:

-3x + 4y = -22

2x + 7y = 5

Let's solve this using elimination, so multiply the first equation by 2 and the second equation by 3:

2 * (-3x + 4y = -22)  ⇒  -6x + 8y = -44

3 * (2x + 7y = 5)  ⇒  6x + 21y = 15

Our equations are now:

-6x + 8y = -44

6x + 21y = 15

Add these two together to eliminate the x term:

    -6x + 8y = -44

+    6x + 21y = 15

______________

     0x + 29y = -29

y = -29/29 = -1

Plug this back into one of the equations to find x:

-3x + 4y = -22

-3x + 4 * (-1) = -22

-3x - 4 = -22

-3x = -18

x = -18/(-3) = 6

The answer is (6, -1) or A.

Answer:

A. (6,-1)

Step-by-step explanation:

-3x + 4y = -22

2x + 7y = 5

x = (5 - 7y)/2

-3[(5 - 7y)/2] + 4y = -22

-15/2 + 21y/2 + 4y = -22

29y/2 = -29/2

y = -1

x = (5 - 7(-1))/2

x = 12/2

x = 6
