Please answer correctly !!!!!!!!!!! Will mark brainliest !!!!!!!!!!!!

Answer:9

Step-by-step explanation:

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator. Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1. (14/2 x 3/3)+(12/6 x 1/1). Complete the multiplication and the equation becomes  42/6+12/6. The two fractions now have like denominators so you can add the numerators. 42+12/6=54/6. Divide 54 by 6 and get 9. hope this helps :)

Step-by-step explanation:

Answer:

Step-by-step explanation:

a)7x + 2 = -19  {subtract 2 from both sides}

7x + 2 -  2 = -19 - 2

            7x = -21   {Divide both sides by 7}

         7x/7 = -21/7

             x = -3

b) 3x - 1/3 = 5

3x - 1/3 +1/3 = 5 + 1/3  {Add 1/3 to both sides}

               3x =15/3 + 1/3

               3x =16/3

             3x/3 = 16/3*3 {Divide both sides by 3}

                 x =16/9

                 x =1 7/9

c) 5x - 4  = 21

5x -4 + 4 = 21 +4 {Add 4 to both sides}

          5x = 25

       5x/5 = 25/5    {Divide both sides by 5}

            x = 5

d) -7x  = 21 {Divide both sides by -7}

-7x/-7 = 21/-7

        x = -3

e)   18 - 7x = -3

18 - 7x - 18 = -3 - 18   {Subtract 18 from both sides}

          -7x = -21   {Divide both sides by -7}

      -7x/-7 = -21/-7

              x = 3

f)     3(x+4) = 21   {use distributive property}

   3x + 3*4 = 21

    3x  + 12 = 21

3x + 12 - 12 = 21 - 12       {Subtract 12 from both sides}

              3x = 9   {Divide both sides by 3}

           3x/3 = 9/3

                 x = 3

g)     3x - 9 = 5x - 3  {add 9 to both sides}

 3x - 9 + 9 = 5x - 3 + 9

             3x = 5x + 6

       3x - 5x = 5x + 6 - 5x     { subtract 5x form both sides}

             -2x = 6  {Divide both sides by -2}

         -2x/-2 = 6/-2

                 x = -3

h) 4x + 6 - 7x + 9 = 18   {Add the like terms}

           -3x  + 15 = 18  {Subtract 15 from both sides}

      -3x + 15 -15 = 18 - 15

                    -3x = 3   {Divide both sides by -3}

               -3x/-3 = 3/-3

                      x = -1

[tex]i) \frac{-4}{9}x = -36[/tex]

Multiply both sides by 9

[tex]9*\frac{-4}{9}x =9*-36[/tex]

 -4x = -324     {Divide both sides by -4}

-4x/-4 = -324/-4

       x = -81

[tex]j)\frac{-7}{8}x - 6 = 8[/tex]   {Add 6 to both sides}

[tex]\frac{-7}{8}x-6+6=8+6\\\\\frac{-7}{8}x=14\\[/tex]    {Multiply both sides by 8}

[tex]\frac{-7}{8}x*8=14*8\\\\-7x=14*8\\[/tex]       {Divide both sides by -7}

[tex]\frac{-7}{-7}x=\frac{14*8}{-7}[/tex]

x =-2*8

x = -16

Answer:

7 7/24

Step-by-step explanation:

first put the wholes inside the fraction:

[tex]1 \frac34 = \frac44 + \frac34 = \frac74[/tex]

[tex]4 \frac16 = \frac{24}{6} + \frac16 = \frac{25}{6}[/tex]

Then multiply numerator times numerator, denominator times denominator and take out wholes again:

[tex]\frac74 \times \frac{25}{6} = \frac{7 \times 25}{4 \times 6} = \frac{175}{24} = 7 \frac{7}{24}[/tex]

Answer:

0+8

Step-by-step explanation:

add 8 each time

it is 0 because in times table if you have 8, 16 and 24 then you don't need to add it on or take away from it, so it will be 0.

I hope that helped.

∠5 = 118

Step-by-step explanation:

If you look closely at this image, you can see that ∠6 and ∠5 together will be equal to line c.

A straight line is equal to 180 so if we do...

[tex]180-62[/tex]

= 118.

∠5 will be equal to 118.

If we go even further, because vertical angles are congruent...

∠7 = 62

∠8 = 118

Answer:

[tex] m \angle \: 6 = 118 \degree[/tex]

Step-by-step explanation:

[tex]m \angle \: 5 + m \angle \: 6 = 180 \degree.. (straight \: line \: \angle s) \\ \because \: m \angle \: 5 = 62 \degree \\ \therefore \: 62 \degree+ m \angle \: 6 = 180 \degree \\ \therefore \: m \angle \: 6 = 180 \degree - 62 \degree \\ \huge \red{ \boxed{\therefore \: m \angle \: 6 = 118 \degree}}[/tex]

Then add the tip to the original number.

Answer:

y = (x + 4)(x + 3)

Step-by-step explanation:

y = x ^2 + 7x + 12

The two numbers must add up to 7 and has a product of 12, and since the equation is all positive, then the two numbers are positive too.

So y = (x + 4)(x + 3) is the answer.

Check:

y = (x + 4)(x + 3)

y = x(x + 3) + 4(x + 3)     distributive property

y = x^2 + 3x + 4x + 12

y = x^2 + 7x + 12

Answer:

20 counters.

Step-by-step explanation:

50/200 or 1/4 of the counters have white paint on them.

That means you can expect 1/4 of the 80 counters pulled out to have white paint on them or 20 counters.

Answer:

28

Step-by-step explanation: You need to divide 7 by 1/4. Whenever you divide fractions you keep the first number as it is, change the sign to multiplication and write the reciprocal of the second fraction which is you have to flip the fraction. It is going to be 7 times 4/1. Which is 28/1 which is 28.

Answer:

[tex]68\frac{1}{4}[/tex] pounds

Step-by-step explanation:

The combined weight of 13 bags is 13 multiplied by the weight of each bag.

The weight of each bag is [tex]5\frac{1}{4}[/tex] pounds. Therefore, the weight of 13 bags is:

[tex]5\frac{1}{4} * 13\\ \\= \frac{21}{4} * 13\\[/tex]

[tex]= 68\frac{1}{4}[/tex] pounds

Answer: The equations have no solution because no solution graphs have the same slopes but difference y- intercepts.And by looking at the equations they both have same slope as 3 but different y-intercepts 5 and -5.

Step-by-step explanation:

Answer:

A. 55h + 275 = 440; h=3

Step-by-step explanation:

Since all answer choices have a different H= , finding how many hours you have left to drive will give you the right answer.

You've already driven 275 miles in your 440 mile trio so you can subtract the 275 to find out how much you will still need to drive.

440 - 275 = 165

You already know that you are driving at 55 mph so divide 165 by 55 and the answer is three.

Option A was the only answer choice which listed h=3 so that is the correct answer.

Answer:

-0.5 or -1/2 or A

Step-by-step explanation:

180 degrees is Pi radians.  To find out what the measure is in the paranthesees, divide 180 by 6 and get 30.  Now multiply it by 7 to get 210.  The question is asking for the sin(210).  The sin of 210 is -0.5

Answer:

16.5x = 465.3

Step-by-step explanation:

The distance traveled is equal to the gallons time the miles per gallon

465.3 = 16.5 * x where x is the miles per gallon

16.5x = 465.3

Answer:

-2x^2-8x+12

Step-by-step explanation:

f(x)= 3x^2-2x+4

g(x)= 5x^2 +6x -8

(f-g)(x) =  3x^2-2x+4-(5x^2 +6x -8)

Distribute the minus sign

(f-g)(x) =  3x^2-2x+4-5x^2 -6x +8

Combine like terms

-2x^2-8x+12
