−<span>2.8
</span>Okay so "0.9x-1.3=-3.1" x=-2
<span><span><span>0.9x</span>−1.3</span>=<span>−3.1
</span></span>add 1.3 to both sides
<span><span><span><span>0.9x</span>−1.3</span>+1.3</span>=<span><span>−3.1</span>+1.3
</span></span><span><span>0.9x</span>=<span>−1.8
</span></span>divide both sides by 0.9
<span><span><span>0.9x/</span>0.9</span>=<span><span>−1.8/</span><span>0.9
</span></span></span>x=<span>−2</span>
So if you plug in -2 into "x-0.8" you get −2.8
<span>=<span><span>−2</span>−0.8
</span></span><span>=<span><span>−2-</span><span>0.8
</span></span></span><span>=<span>−2.8
</span></span>Hope this helps.
Answer:
I believe it is 50% decreased, not sure
Step-by-step explanation:
Answer:
13/36
Step-by-step explanation:
This number cannot be simplified because one of the constituents is prime number, which is number 13.
prime numbers are numbers that can only be divided by 1 and divided by the numbers themselves
Answer:
2x^2
Step-by-step explanation:
The coefficients of the terms in this expression are 8, 4, and 18.
The largest number that you can divide all of them with and get a whole number is 2.
So, 2 is part of our greatest common factor.
These terms also have the variable x. The exponent of the smallest x term is 2, so x^2 is the other part of our greatest common factor.
The rate of the change is 1
