Answer: 26
Step-by-step explanation:
Let the number be n.
Now,
twice a number =>> 2n
added to 3 =>> 2n + 3
is divided by the number plus 7 is five thirds =>> (2n + 3) / (n + 7) = 5 / 3
(2n + 3) = (5 / 3) × (n + 7)
3 × (2n + 3) = 5 × (n + 7)
6n+9 = 5n + 35
6n - 5n = 35 - 9
n = 26
Answer:x=100
Step-by-step explanation:
Since you know that g(x)=3x-11 all you have to do is substitute that into g(x)=289. So you get 3x-11=289. To get x you have to add 11 on both sides.
3x-11=289
+11 +11
----------------
3x = 300
Divide 3 on both sides to get x by itself
3x =300
---- -------
3 3
x=100
On the top problem: Angle A and Angle B are a right angle so it equals 90 degrees. If Angle B is 50 degrees that makes Angle A 40 degrees. Angle A and Angle C is a straight line and equals 180 degrees so if Angle A equals 40 degrees that means Angle C equals 140 degrees.
-3x^2-2x (+-)6=0
ax^2+bx+c
a=-3
b=-2
c= either positive or negative 6 (there is no plus or minus in your question.)
