Solve for y: 2½y = ⅝ Answer in simplest form.

MrMuchimi

Step-by-step explanation:

$2 \frac{1}{2} y = \frac{5}{8}$

Convert Mixed number to improper fraction.

$2 \frac{1}{2} = \frac{5}{2}$

Equate

$\frac{5}{2} y = \frac{5}{8}$

Cross Multiply

$5y \times 8 = 2 \times 5 \\ 40y = 10$

Divide both sides of the equation by 40

$\frac{40y}{40} = \frac{10}{40}$

Simplify

$y = \frac{1}{4}$

RideAnS [48]

Step-by-step explanation:

$\displaystyle f'(x) = \lim_{h \to 0} \dfrac{f(x + h) - f(x)}{h}$

$\:\:\:\:\:\displaystyle = \lim_{h \to 0} \dfrac{(x+h)^2 -7 -(x^2 - 7)}{h}$

$\:\:\:\:\: \displaystyle= \lim_{h \to 0} \dfrac{(x^2 +2hx + h^2 -7) - (x^2 -7)}{h}$

$\:\:\:\:\: \displaystyle= \lim_{h \to 0} \dfrac{2hx + h^2}{h}$

$\:\:\:\:\: \displaystyle= \lim_{h \to 0} (2x +h)$

$\:\:\:\:\: \displaystyle= 2x$
