Hey!

-----------------------------------------------------------------

We know that (a = -3), (b = 2), (c = 5), (d = -4).

-----------------------------------------------------------------

Solution:

= 4c + d

= 4(5) + (-4)

= 20 - 4

= 16

Solve 25+10*(12-x)=5*(2x-7)
lions [1.4K]
<span>Simplifying 25 + 10(12 + -1x) = 5(2x + -7)
25 + (12 * 10 + -1x * 10) = 5(2x + -7)
25 + (120 + -10x) = 5(2x + -7)
 
Combine like terms: 25 + 120 = 145 145 + -10x = 5(2x + -7)
 
Reorder the terms:
145 + -10x = 5(-7 + 2x)
145 + -10x = (-7 * 5 + 2x * 5)
145 + -10x = (-35 + 10x)
 Solving 145 + -10x = -35 + 10x
 
Solving for variable 'x'.
 
Move all terms containing x to the left, all other terms to the right.
 
Add '-10x' to each side of the equation.
145 + -10x + -10x = -35 + 10x + -10x
 Combine like terms: -10x + -10x = -20x 145 + -20x = -35 + 10x + -10x
 
Combine like terms: 10x + -10x = 0 145 + -20x = -35 + 0 145 + -20x = -35
 Add '-145' to each side of the equation. 145 + -145 + -20x = -35 + -145

Combine like terms: 145 + -145 = 0 0 + -20x = -35 + -145 -20x = -35 + -145

Combine like terms: -35 + -145 = -180 -20x = -180
  Divide each side by '-20'.
x = 9
 Simplifying x = 9.

Which expression is equivalent to |b| &gt;2?
vovangra [49]

Answer:

The equivalent expression for |b| > 2 is {b : b < -2} ∪ {b : b > 2}.

Step-by-step explanation:

The expression |x| < a is equivalent to -a < x < a and the expression |x| > a is equivalent to {x : x < -a} ∪ {x : x > a}.

This means, the set of all points that satisfy the inequality |x| < a is the set of all points between -a and a exclusive of -a and a.

The set of all points that satisfy the inequality |x| > a is the set of all points that are less than -a and the set of all points that are greater than a.

Hence, the equivalent expression for |b| > 2 is {b : b < -2} ∪ {b : b > 2}.
