Answer:
5
Step-by-step explanation:
(-8)-(-13)= 5
Answer:
$360
Step-by-step explanation:
12 months in a year
12 x 30 = 360
$360
An expression does not include an equal sign.
A variable is an unknown value
An example of an expression with a variable : 4 + x
<h3><u>The variable x is equal to (p + 11)/5.</u></h3>
P = 5x - 11
<em><u>Add 11 to both sides.</u></em>
p + 11 = 5x
<em><u>Divide both sides by 5.</u></em>
(p + 11)/5 = x
The value placed in the box that makes the system of equation with infinitely many solution is 12.
<h3>How to solve an infinitely many solution equation?</h3>
An infinite solution has both sides equal. For example, 6x + 2y - 8 = 12x +4y - 16. If we simplify the equation we will notice both sides are equal. This means the equation has an infinitely many solution.
Hence,
y = -2x + 4
Therefore,
6x + 3y = 12
divide the equation(ii) by 3
2x + y = 4
y = -2x + 4
Therefore, both equation are equal if the the box is filled with 12. This means for the value placed in the box that makes the system of equation with infinitely many solution is 12.
