1) 3x-7y=2
2) If you're solving for x, you want to isolate it, so move the -7y to the right:
3x = 7y + 2
3) Now, to get x by itself, you divide both sides by 3
3x/3 = (7y + 2)/3
4) You get:
x = 7/3y + 2/3
The <em><u>correct answer</u></em> is:
negative six and thirty-three fortieths
Explanation:
To multiply (2 5/8)(-2 3/5), we first change each mixed number to an improper fraction. To do this, we multiply each whole number by the denominator and add the numerator:
(2*8)+5 = 16+5 = 21; this makes 2 5/8 = 21/8
(2*5)+3 = 10+3 = 13; this makes -2 3/5 = -13/5
This gives us
(21/8)(-13/5) = (21*-13)/(8*5) = -273/40
40 will go into 273 6 times; this gives us the number -6. There is then 270-240 = 33 left over; this gives us 33/40, and a total of -6 33/40.
A and D I think plz don’t get mad if I get it wrong
The answer is 670.408, because 6x100=600, 7x10=70, 4x1/10 as a decimal is 0.4, 8x1/1,000 as a decimal is 0.008. Then, you add all of those
