Answer:
-16.3 ≥ q
Step-by-step explanation:
–5.3 ≥ 6.7 + 4.3 + q
Combine like terms
–5.3 ≥ 11 + q
Subtract 11 from each side
–5.3-11 ≥ 11-11 + q
-16.3 ≥ q
Well, the numerator is the number on top, so in the fraction 3/5, 3 is the numerator. To find the equation with a denominator of 30 that is equivalent, find what the difference is. 30/5 = 6. So now, multiply the numerator by 6. 6 * 3 = 18. The new fraction is 18/30. The numerator is 18. Hope this helps!
Answer:
-72 X + 14
Step-by-step explanation:
To complete a square for ax²+bx+c, you first make a=1.
in this case, a is already 1
move c to the right side: x²+14x=-47
next, add (1/2 of b)² to both sides, in this case, b=14, half of 14 is 7, so x²+14x+ 7²=-47+7²
the left side is now a perfect square: (x+7)²=2
x+7=√2 or x+7=-√2
x=√2-7, or x=-2-√7
