a + (-5) = 12

Open the bracket;

a - 5 = 12

Add 5 to both sides

a - 5 + 5 = 12 + 5

Therefore,

a = 17

Answer 2

Answer:

a=17

Step-by-step explanation:

any number plus a negative number is basically subtracting the absolute value of the negative number. so 12 + 5 = 17

Brian's monthly gross income is $2,950. He pays 22% of his monthly gross

earnings in federal and state taxes and spends 10% of that monthly income to

pay off his credit card debt. Brian is also paying off a loan his parents gave him

for a new car by sending them 8% of his income per month. Brian found an

apartment near his work that rents for $1,300 per month. Will he be able to make

the payments without changing the amounts he pays towards his loan and credit

card debt?

Answers

Answer:

Yes

Step-by-step explanation:

I = 2950

T = 22% x 2950 = 649

CC = 10% x 2950 = 295

NC = 8% x 2950 = 256

R = 1300

I - (T + CC + NC + R) > 0

2950 - ( 649+ 295 + 256 + 1300) > 0

2950 - 2500 >= 0

450 > 0

Find the value of X express each answer as a decimal rounded to the nearest tenth.

Answers

Answer:

x = 15.6

Step-by-step explanation:

use the pythagorean theorem:

a² + b² = c²

a = 9

b = x

c = 18

(9)² + x² = (18)²

81 + x² = 324                    subtract 81 from both sides

x² = 243                            take the square root of both sides

x = √243

x = 15.6

Suppose someone gives you 6 to 1 odds that you cannot roll two even numbers with the roll of two fair dice. This means you win 6 dollars if you succeed and lose 1 dollar if you fail. What is the expected value of this game to you. What can you expect if you play 200 times

Answers

Answer:

0.75 ;

150

Step-by-step explanation:

Probability of rolling two even numbers :

{1, 2, 3, 4, 5, 6}

P(even) = 3 / 6 = 1/2

From a roll of 2 dice :

P(even) * P(even) = 1/2 * 1/2 = 1/4 = 0.25

P(not even) = 1 - 1/4 = 3/4

X : ____ 6 _______ - 1

P(x) ____ 0.25 ____ 0.75

Expected value :

Σx*p(x) = (6*0.25) + (-1 * 0.75)

= 1.50 - 0.75

= 0.75

If 200 games are played :, n = 200

Expected value * n

0.75 * 200

= 150

Raymond's bake shop sold 26 1/2 cupcakes on Saturday on Friday the bake shop sold 19 3/4 dozen cupcakes what is the approximate percent increase in cupcake sales from Friday to Saturday

Answers

Answer: 34.18%  

Step-by-step explanation:

Given: On Saturday, Number of cupcakes sold = [tex]26\dfrac12[/tex] dozens

= [tex]\dfrac{53}{2}[/tex] dozens

[tex]=\dfrac{53}{2}\times12[/tex]    [  1 dozen = 12 items]

[tex]=53\times6\\\\=318[/tex]

On Friday, Number of cupcakes sold = [tex]19\dfrac34[/tex] dozens

= [tex]\dfrac{79}{4}[/tex] dozens

[tex]=\dfrac{79}{4}\times12[/tex]    [  1 dozen = 12 items]

[tex]=79\times3\\\\=237[/tex]

Increase in cupcakes = 318-237=81

Percent increase in cupcakes sales from Friday to Saturday = [tex]\dfrac{81}{237}\times100[/tex]

= 34.18%   (approx)

The approximate percent increase in cupcake sales from Friday to Saturday = 34.18%

if zaeirr has 10 dogs and lamarr has 2 dogs how many more dogs does zaeirr have than lamarr?

Answers

Answer: 8

Step-by-step explanation:

For this problem, we would have to subtract the larger number of dogs by the smaller number of dogs. Zaierr has 10 dogs, and Lamarr has 2 dogs. We would have to subtract the number 10 by the number 2 to get our answer.

10 subtracted by 2 is equal to the number 8.

The answer to our question is 8.

10-2 = 8

So Zaeirr has 8 more dogs
