The only number you can add to √7 to get a rational number is a-√7 where a is any rational number.
So if a=0 the answer is -√7, option answer 1.
2y/5 is the same thing as 2/5 times y so
14=2/5(y) then you divide both sides by y and you get
14/y=2/5 then from there multiply both sides by 1/14 to get
y=0.03
Answer:
x ≤ 1/2
Step-by-step explanation:
1/2(4x - 2) - 2/3(6x + 9) ≤ 4
2x-1 - 4x+6 ≤ 4
2x-4x-1+6 ≤ 4
-2x + 5 ≤ 4
-5 -5
-2x ≤ -1
2x ≤ 1
2x/2 ≤ 1/2
x ≤ 1/2
