Answer: 13

Step-by-step explanation:

Distribute t.

Multiply 3 by each value in parentheses to get

3t - 12 = 2t + 1

Add 12 to both sides

3t = 2t + 13

Subtract 2t from both sides

t = 13

4.
b^-2-x^-2/b^-1+x^-1

b^-2/b^-1=b^-1
x^-2/x^-1=x^-1
As a result, the simplest form is:
b^-1-x^-1. Hope it help!

Put the equation in standard form with a positive x coefficient. 2y+5=-4(x+2)

umka21 [38]

The standard form of equation is: 4x+2y = -13

Step-by-step explanation:

the standard form of a linear equation in two variables is given by:

$ax+by = c$

Given equation is:

$2y+5=-4(x+2)$

Distributing -4 into the round bracket

$2y+5 = -4x-8$

Adding 4x on both sides

$4x+2y+5 = -4x-8+4x\\4x+2y+5 = -8$

subtracting 5 from both sides

$4x+2y+5-5 = -8-5\\4x+2y = -13$

The standard form of equation is: 4x+2y = -13

What is the value of the expression |a + b| + |c| when a = –3, b = 7, and c = –15?

nikdorinn [45]

We know:
$|a|= \left\{\begin{array}{ccc}a&if\ a \ \textgreater \ 0\\0&if\ a=0\\-a&if\ a \ \textless \ 0\end{array}\right\\\\|2|=2\\|0|=0\\|-3|=3$

$|a+b|+|c|$
substitute a = -3; b = 7; c = -15
$|-3+7|+|-15|=|4|+15=4+15=19$
