Factor −1/4 out of −1/2x−5/4y. The factored expression is .

Olegator [25]

Answer:

(-1/4)(2x +5y)

Step-by-step explanation:

Multiply and divide by -1/4:

$-\frac{1}{2}x-\frac{5}{4}y=\dfrac{(-\frac{1}{4})(-\frac{1}{2}x-\frac{5}{4}y)}{-\frac{1}{4}}=\left(-\dfrac{1}{4}\right)(-4)\left(-\dfrac{1}{2}x-\dfrac{5}{4}y\right)\\\\=\left(-\dfrac{1}{4}\right)\left(2x+5y)$

Rate (R) = 25/3<br>Interest = Rs. 350<br>(d) Principal = Rs. 2400<br><br>Find the time (t)

julia-pushkina [17]

Answer:

The value of t is 1.75 years.

Step-by-step explanation:

Given that simple interest formula is I = (P×R×T)/100. So you have to substitute the following values into the formula :

$i = \frac{prt}{100}$

$let \: i = 350,p = 2400,r = \frac{25}{3}$

$350 = \frac{2400 \times \frac{25}{3} \times t }{100}$

$350 = \frac{20000t}{100}$

$350 \times 100 = 20000t$

$20000t = 35000$

$t = 35000 \div 20000$

$t = 35 \div 20$

$t = 1.75 \: years$
