Use the distributive property to remove the parentheses.<br> 10(u-2)

andrey2020 [161]

Answer:

After using distributive property to remove the parentheses $10(u-2)$ we get $10u-20$

Step-by-step explanation:

We need to use distributive property to remove the parentheses 10(u-2)

According to distributive property of multiplication over subtraction: $a(b-c)=ab-ac$

Using the above distributive property to solve the question. Multiply 10 with terms inside the bracket and solving:

$10(u-2)\\=10u-10*2\\=10u-20$

So, After using distributive property to remove the parentheses $10(u-2)$ we get $10u-20$

Solve this system of linear equations. Separate

attashe74 [19]

Answer:

$(-\frac{7}{13},\frac{79}{13})$

Step-by-step explanation:

Given:

Two equations are given.

$- 7x + 3y = 22$ ------(1)

$4x + 2y = 10$ ----------(2)

Solve equation 1 for y.

$- 7x + 3y = 22$

$3y = 22+7x$

$y=\frac{22+7x}{3}$ -----------(3)

Now, we substitute y value in equation 2.

$4x + 2(\frac{22+7x}{3}) = 10$

$\frac{12x + 2(22+7x)}{3} = 10$

$12x + 2(22+7x)=10\times 3$

$12x + 44+14x=30$

$26x=30-44$

$26x=-14$

$x=-\frac{14}{26}$

$x=-\frac{7}{13}$

Now, we substitute x value in equation 1.

$- 7(-\frac{7}{13}) + 3y = 22$

$\frac{7\times 7}{13} + 3y = 22$

$\frac{49}{13} + 3y = 22$

$3y = 22-\frac{49}{13}$

$3y = \frac{13\times 22-49}{13}$

$3y = \frac{286-49}{13}$

$y = \frac{237}{13\times 3}$

$y = \frac{237}{39}$

$y = \frac{79}{13}$

Therefore, the value of x and y is $(x=-\frac{7}{13},y = \frac{79}{13})$
