Find −5 5/6÷(−4 9/10). Write your answer as a mixed number in simplest form.

uranmaximum [27]

Answer: $1\dfrac{4}{21}$ .

Step-by-step explanation:

Given problem : $\left(-5\dfrac{5}{6}\right)\div\left(-4\dfrac{9}{10}\right)$

First we convert mixed fraction into improper fractions as

$-5\dfrac{5}{6}=-\dfrac{5\times6+5}{6}=-\dfrac{30+5}{6}=-\dfrac{35}{6}\\-4\dfrac{9}{10}=-\dfrac{10\times4+9}{10}=-\dfrac{40+9}{10}=-\dfrac{49}{10}$

Now , plug these values in the given expression , we get

$\left(-5\dfrac{5}{6}\right)\div\left(-4\dfrac{9}{10}\right)=-\dfrac{35}{6}\div\left(-\dfrac{49}{10}\right)\\\\=\dfrac{-35}{6}\times\dfrac{-10}{49}\ \ \ [\text{By Property of fraction}]\\\\=\dfrac{350}{294}\\\\=\dfrac{25}{21}=1\dfrac{4}{21}$

Hence, the answer is $1\dfrac{4}{21}$ .

2. Given f(x) = 6(8 - x)+5

son4ous [18]

Answer:

a) Find the value of the function when x = -2

b) we get f(-2)=65

Step-by-step explanation:

We are given the function f(x)=6(8-x)+5

a) What does the notation f(-2) mean?

The notation f(-2) means that we have to put x = -2 in the given function of f(x) and find the value of the function when x = -2

b) What is the value of f(-2) ?

We need to find the value of f(-2)

$f(x)=6(8-x)+5$

Put x = -2

$f(-2)=6(8-(-2))+5\\f(-2)=6(8+2)+5\\f(-2)=6(10)+5\\f(-2)=60+5\\f(-2)=65$

So, we get f(-2)=65

Solve for x 1+4x=-5+7x

SVETLANKA909090 [29]

Steps to solve:

1 + 4x = -5 + 7x

~Subtract 1 to both sides

4x = -6 + 7x

~Subtract 7x to both sides

-3x = -6

~Divide -3 to both sides

x = 2

Best of Luck!
