Whats The Answer To This ???

Answers

Answer 1

Answer:

-5, 3

Step-by-step explanation:

3) 10+3n=20+5n Set up the problem

        -3n       -3n Subtract 3n from both sides to get n on one side of the equation.

    10     =20-2n

    -20     -20 Subtract 20 from both sides to isolate n

     -10    =2n

      /2       /2 Divide both sides by 2 to isolate n

      -5    =   n

4) 18=2(b+6) Write down problem

   18=2b+12 Distribute

    -12     -12 Subtract 12 from both sides to isolate b

    6=2b

     /2/2 Divide both sides by 2 to isolate b

     3=b

Answer 2

Answer:

3) 3x+10 = 5x+20

=> 3x-5x= 20-10

=> -2x= 10

=> x = 10/-2

=> x= -5

4) 2(b+6) = 18

=> 2b +12 = 18

=> 2b = 18-12

=> b= 6/2

=> b = 3

Answer:

5) First you have to find x, then use it with supplementary angles theorem.

6) STQ = 150˚

Step-by-step explanation:

To find x, add (2x+8), (71-x), and 90˚ together to add up to 180˚ (those three angles are supplementary):

(2x+8) + (71-x) + 90 = 180˚

x + 169 = 180

Then solve for x:

x = 11

You can check if x is right by inputing it back into the two equations and see if all three of the angle measures together equal 180˚.

Now, you only need m∠MTS (2x+8) to find m∠STQ...

m∠MTS + m∠STQ = 180˚ because they are supplementary angles.

Input the found x to find m∠MTS:

(2(11)+8) = 30

Subtract 30 from 180 to find m∠STQ:

180 - 30 = 150

m∠STQ = 150˚

Carrah has these cans of soup in her kitchen:
2 cans of tomato soup
3 cans of chicken soup
2 cans of cheese soup
2 cans of potato soup
1 can of beef soup
Carrah will randomly choose one can of soup. Then she will put it back and randomly choose another can of soup. What is the probability
that she will choose a can of tomato soup and then a can of cheese soup?

Answers

2/10 (or 1/5 ) Times 2/10 (or 1/5).

This will equal a 1 out of 25 chance.

You take the number of items you are looking for ( for example, 2 Tomato Cans) Divided by the total items you have (All 10 cans that are a possibility). Then you take your probabilities, and multiply them.

Answer:

6 bowls of ramen

Step-by-step explanation:

because $1.50 * 4 is 6

49.50 - 6 = 43.50

43.50/7.25 = 6

Answer:

a)2(1.50)+7.25x=47.50

b) about 6 bowls.

Step-by-step explanation:

Right off the bat, we know that each drink is $1.50. So buying two would be $3 so far. Subtract $3 from $49.50. Getting $47.50. Now we know the drinks so we must divide 47.50 by 7.25, equalling 6.5 and so on. To round it we can say 6 bowls.

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    1/3+a-(5/4*a)=0

                 5

Simplify   —

                 4

    1                 5

 ( — +  a ) -  ( — • a )  = 0

   3                 4

                 1

Simplify   —

                 3

Solve  :    -3a+4 = 0

Subtract  4  from both sides of the equation :

                     -3a = -4

Multiply both sides of the equation by (-1) :  3a = 4

Divide both sides of the equation by 3:

                    a = 4/3 = 1.333

Simplify: (9a* - 5a'-1)+7a*
