Simplify each expression involving signed numbers.


-7 – 2 =
12 + (-4) =
-8(-6) =

18/-3=

Answers

Answer 1

Answer:

-5 , 8 , 48 , -6

Step-by-step explanation:

-7- -2 = -5

This complies with the rule that 2 negatives make a positive.

12 + (-4) = 8

You just ignore the brackets.

-8(-6) = 48

The -8 next to the bracket with no symbol means you need to multiply, and again 2 negatives make a positive.

18/-3 = -6

As the 18 is not negative, but -3 is, the answer is also a negative because one negative and one positive make a negative!

Hope this helps and have a good day!

Answer 2
-5 8 48 and -6

Answers

Answer:

Step-by-step explanation:

switch signs because you're dividing by a negative number

-2x/-2 < -12/-2

Hope this helps :)

Answer:

x > 6

Step-by-step explanation:

Solve -2x <-12 for x.  Your answer must be a set of real numbers.

Divide both sides by -2.  Note that if we here divide by a negative number, we must reverse the direction of the inequality symbol:

-2x < - 12

Answer:

Descends: 2,312 x 2.6 = - 6,011 (when rounding otherwise known as - 6,011.2, this number is negative because he is descending)

During a period of extreme cold, the average daily temperature dropped decreased by 112°F day. How many days did it take for the temperature to decrease by 9°F? Which equation would you use to find the solution?

A x + 112 = 9x + 112 = 9

B x − 112 =−9x − 112 =−9

C −112x = −9−112x = −9

D 112x = 9

Answers

It takes about 4 days for the temperature to decrease by 9°F.

An equation is an expression that shows the relationship between two or more variables or numbers.

Let x represent the number of days. Given that the temperature drop decreased by 1 1/2°F each day (- 1 1/2), for it to decrease by 9°F (-9):

-1 1/2 * x = -9

-1.5x = - 9

x = 4 days

It takes about 4 days for the temperature to decrease by 9°F.

Pete wants to buy a new PlayStation 5 controller that is on sale. The controller cost $70 and is on sale for 40% off. If the sales tax is 10.1% how much will he pay for the controller?

Answers

Answer:

Your answer is $52.2 :)

Step-by-step explanation:

First, we need to find the sale, which is 40% of $70, we can do that by doing this equation: (40% x $70) / 100 = 28.  Now we minus 28 from 70 in this equation: 70 - 28 = 42.  Now we do tax, which is 10.1% of $42.  We can do the same equation, but with the new information, so the new equation is ($42 x %10.1) / 100 which is 4.2042, and since we are talking money, we can make 4.2042, 4.2 (Rounded 0.042 down). Lastly, we add $4.2 (Tax) and $48 (Discounted price) to get $52.2. You're welcome :D

The answer would be 46.24 because 40% off of 70 is 42 and forty two mutiplied by .101 would be 4.24

Answer:

  1) 2^9 = 512

  2) 2^(3t) = 2^6 for t=2

Step-by-step explanation:

1) An exponent is used to signify repeated multiplication. Here, the factor 2 is repeated 9 times, so the expression can be written using an exponent as ...

  2^9

Using any of a variety of means, the value of this expression can be found to be ...

  2^9 = 512

__

2) Assuming the bacteria reproduce by multiplying by some factor in a given time, we can divide the original expression into 3 parts:

  (2×2×2) × (2×2×2) × (2×2×2)

If this represents the number after 3 hours, then the number after 2 hours is expected to be ...

  (2×2×2) × (2×2×2) = 2^6

That is, there will be (2 h)/(3 h) = 2/3 times as many multiplications by a factor of 2. (2/3)(9) = 6 will be the exponent for the number after 2 hours.

1. 2^9 = 512
2. as you can split up the fact in 3 hours it is 2^9 to find out one hour (divide by 3) which is 2^3 so we would just multiply it by 2 which equals 2^6
