Answer:
80/3 or 26 2/3
Step-by-step explanation:
-2 + y = 9 (subtract y from both sides)
-2 = 9 - y (subtract 9 from both sides)
-2 - 9 = y (multiply both sides by -1)
2 + 9 = y (simplify)
11 = y (substitute)
3x - 7 (11) = 3 (multiply)
3x - 77 = 3 (subtract 3 from both sides)
3x - 80 = 0 (subtract 3x from both sides)
-80 = -3x (multiply both sides by -1)
80 = 3x (divide both sides by 3)
80/3 = x (simplify if needed)
26 2/3 = x
Try getting rid of the decimal. then divide 225 by 5.
the answer will be 45 nickels
Answer: 3 kg 605 g
Step-by-step explanation:
Multiply both parts of the equation by V:
That's geometric sequence
T7 = T5*r^2 = T5+1920
r = 2, so
4*T5 = T5 + 1920
3T5 = 1920
T5 = 640
640 = 2^4 * 40
So, a=40 and the sequence is
40 80 160 320 640 1280 2560 5120 10240 20480 40960 ...
Note that 2560 = 640 + 1920

To determine the solution of the given equation, we can use the quadratic formula which is expressed as:
x = (-b +/- √b^2 - 4ac ) / 2a
where a, b and c are the coefficients of the equation ( ax^2 + bx + c = 0)
USing the formula above we obtain the values:
x = 21
x = 3/4
Hope this answers the question. Have a nice day.
