So solving this you would change the greater than sign to an equal sign 3+4n=31 then you would solve this by subtracting 3 from 31 which gives you 28 so then you have 4n=28 then you divide each side by 4 to get n by itself which gives you n=7 so then you would change back the sign to n>7
the other problem you would do the same thing so 2n-6=18 the first step you would do is add 6 to both sides, 2n=12 then divide both sides by 2 n= 6 then change back the sign n<6 (less than or equal to) make sure to add the dash under the last problem i just couldn’t add it to this on my phone.
Answer:
a+b=5/2a, a+b=5/3b
Step-by-step explanation:
1.2a=0.8b
6/5a=4/5b
6a=4b
b=3/2a, a=2/3b
a+b=3/2a+a
a+b=5/2a
a+b=2/3b+b=5/3b

22/8 = x/36
11/4 = x/36
36(11)/4 = x
396/4 = x
x = 99
Answer:

Step-by-step explanation
Multiply the value by 1.38.
Suppose <span>A</span><span> is invertible. Therefore the equation </span><span><span>Ax=0</span></span><span> has only one solution, the zero solution. This means that the columns of </span><span>A</span><span> are linearly independent.</span>
