Answer:

- 18

Step-by-step explanation:

For this problem, you want to replace the letters with the values they gave you so...

b - 8c into -2 - 8 (2)

1) Simplify 8 × 2 to 16.

−2 − 16

2) Simplify.

−18

Answer:

x = 29

Step-by-step explanation:

⇒ x + ( 2 x + 2 ) + ( 3 x + 4 ) = 180 ⇒ 6 + 6 = 180 ⇒ 6 x = 180 − 6= 174 ⇒ x = 174 6 = 29

Answer:

10

Step-by-step explanation:

you convert the 12% so that it becomes a fraction...it becomes 12\100 , then put it in its lowest form ...

Answer: -5x-8<-13

Step-by-step explanation:

Answer:

You are selecting marbles with replacement. The marble selections (trials) are independent and the marble selection follows the binomial distribution.

The probability of selecting a red marble the first time is 1313.

(This is because 4 out of 12 marbles are red and412412 reduces to 1313.

The probability of selecting a red marble the second time is 1313.

The marble selections are independent and you can multiply the two probabilities to get the following:

probability of getting 2 reds = (13)2(13)2

=19=19.

So the probability of getting two reds is 1919.

Answer:

F

Step-by-step explanation:

To figure out if a set of angles are in a triangle, make sure they add up to 180

F) 58,70,62                 58 + 70 + 62 = 190      This option is incorrect

G) 41,68,71                   41 + 68 + 71 = 180       This option is correct

H) 68,60,52                68 + 60 + 52 = 180    This option is correct

J) 73,42,65                  73 + 42 + 65 =  180     This option is correct

Since option F did not equal 180, F is the answer.

Answer:

18 children

Step-by-step explanation:

The computation of the more children went to scotland is as follows:

Given that

There is 200 children

out of which 18% went to wales i.e. = 200 × 18% = 36

And, 27% went to scotland i.e. = 200 × 27% = 54

So, the more children went to scotland is

= 54 - 36

= 18 children

Answer:

The distance between point R and point Z is 7 blocks below.

Step-by-step explanation:

The question says the distance between Point r and Point Z. R to Z is going down. You start at R and find Z. When you have done that, You count the number of blocks or spaces that they have in between the space. And when you have counted you get your answer. The answer is never a negative number always positve even if the point is has a negative number with posivte or a negivate  with negative or a postive wwith a postive.

Answer:

22 cards

Step-by-step explanation:

Set up a ratio.

[tex]\frac{34}{29+x} =\frac{2}{3}[/tex]

[tex]58+2x=102[/tex]

[tex]2x=44[/tex]

[tex]x=22[/tex]

Check: Add 22 to 39. 22+29=51

34/51 = 2/3

Answer:

-0.0714 approx

Step-by-step explanation:

78x − 12 = 316x + 5

Bring all the like terms together

78x -316x = 5 + 12

-238x = 17

∴ x = 17 ÷ -238 = -0.0714 (rounded up to 3 significant figures)

Step-by-step explanation:

Step 1: Define Systems

y = x - 16

5y = 2x - 56

Step 2: Solve for x

Step 3: Solve for y

Answer:

Solve systems of two linear equations in two variables algebraically, and estimate solutions by graphing the equations. Solve simple cases by inspection. For example, 3x + 2y = 5 and 3x + 2y = 6 have no solution because 3x + 2y cannot simultaneously be 5 and 6.
