Y=2/x-3 make x the subject​
svp [43]
Multiply both sides by x - 3 to get :

y(x - 3) = 2

yx - 3y = 2

yx = 2 + 3y

x = (2 + 3y)/y

Hope this helps! Any questions let me know :)

\bf \begin{array}{ccll}
\stackrel{cake}{oz}&calories\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
7.5&900\\
2.5&x
\end{array}\implies \cfrac{7.5}{2.5}=\cfrac{900}{x}\implies x=\cfrac{2.5\cdot 900}{7.5}

so, the 2.5oz cake will be "x" calories, pheeew, she'll be taking in 900 - x less calories.

Answer:

20 degrees

Step-by-step explanation:

First, draw the triangle and label the sides and angles. (See the picture attached)

The red lines on sides FG and HF indicate that the sides are congruent since this is an isosceles triangle. Isosceles triangles have two congruent sides and angles.

All angles add up to 180 degrees. You were already given 140 for angle F. So, use to find angle h, subtract 140 from 180 and divide by 2.

180 - 140 = 40

40 / 2 = 20

Angle h is 20 degrees
