Combine. Note that one positive and one negative = one negative

-2.1 + (-5.9) + (-3.7) = -2.1 - 5.9 - 3.7 = -11.7

-11.7 is your answer

hope this helps

Hi,

Answer: -11.7

<u>My work:</u> This problem can be easily achieved by taking the number -2.7 and subtracting it with 5.9. (-2.7 - 5.9) Your next step would be to taking the number -8.6 and subtracting it with 3.7. Which brings it to your answer -11.7.

<u><em>My Numerical work:</em></u>

1. -2.1+(-5.9)+(-3.7)

2. -2.1 - 5.9 - 3.7 = -11.7

I Hoped I Helped!

3x+4[2x-3(x+1)-20x]=25x+100
sashaice [31]
Simplify:
3x + 4[2x -3x -3 -20x] = 25x +100
3x + 4(-21x -3) = 25x + 100
3x - 84x -12 = 25x + 100
-81x -12 = 25x + 100
Add 12 and Subtract 25x from each side
-106x = 112
X = -112/106
X = -56/53

Select the assumption necessary to start an indirect proof of the statement. If 3a+7 &lt; 28, then a&lt;7.
pashok25 [27]
When applying indirect proofs, we assume the negation of the conclusion is true, and show that this assumption would lead to nonsense, or contradiction.

In our case we assume a is not smaller than 7, that is we assume a≥7.

a≥7 then, multiplying both sides by 3:
3a≥21, then, adding both sides 7:

3a+7≥28,

which is a contradiction because 3a+7 is smaller than 28.

So our assumption is wrong, which means the opposite of it is correct.


Answer: assume a≥7

For a system of equations such as this, add both of the equations together. The d values will cancel each other out, making 2e=-4. This means that e=-2. If you plug this into one of the equations, you will have d + (-2) = 1. Isolate the variable by adding -2 to both sides: d=3. Written in the format described above (d,e), your answer is (3, -2).
