R=24
I say this because 24 / 2 = 12
You and find this by multiplying 2 to 12 to get it to the other side resulting in
24=r
Answer:
$3.24
Step-by-step explanation:
2.16 / 12 = 0.18
0.18 per egg
0.18 x 18 =3.24
18 eggs = $3.24
Answer:
3^5=9^2x = 3
3^(2x+1) =3^3 = 1
Step-by-step explanation:
Answer:
<em>a^2 +3a-2</em>
Step-by-step explanation:
Given the expression:
g(x) = x^2 +3x-2
We are to find f(a). To get this, we will simply replace x with a in the expression as shown;
g(a) = a^2 +3a-2
<em>hence the required domain is expressed as g(a) = a^2 +3a-2</em>
The solution of the equation is x = -4/3.
<h3>What does it mean to solve an equation?</h3>
An equation represents equality of two or more mathematical expression.
Solutions to an equation are those values of the variables involved in that equation for which the equation is true.
WE have been given an equation as;
|x - 4| = 5x + 12
In an absolute value equation, we solve the original expression as our first equation. Our second one is that we multiply the right side by -1.
Case 1: original equation
|x - 4| = 5x + 12
x - 4 = 5x + 12
x - 5x = 12 + 4
-4x = 16
x = -4
Case 2: Opposite equation
|x - 4| = 5x + 12
x - 4 = - (5x + 12)
x - 4 = - 5x - 12
x + 5x = -12 + 4
6x = -8
x = -4/3
Now we have two solutions. We need to check for extraneous solutions because of all the manipulations;
Check:
|x - 4| = 5x + 12
use x = -4
|-4 - 4| = 5(-4) + 12
| -8 | = -20 + 12
8 = -8
Thus, it is Not a solution
Now, |x - 4| = 5x + 12
use x = -4/3
| -4/3 - 4| = 5( -4/3) + 12
|-16/3 | = -20/3 + 12
|-16/3 | = 16/3
16/3 = 16/3
Thus, it is the Solution.
