Answer:
<h3>- A
dd 9.6 to both sides of the equation </h3><h3>-
Divide both side by the coefficient of x i.e 3.2</h3><h3>
</h3>
Step-by-step explanation:
The first step that can be done to both of the equation given is to add 9.6 to both sides of the equation as shown;
3.2x – 9.6 = 38.4
3.2x – 9.6+9.6 = 38.4+9.6
3.2x = 38.4+9.6
3.2x = 48.0
step 2;
Divide both side by the coefficient of x i.e 3.2
3.2x/3.2 = 48.0/3.2
x = 15
Therefore the value of x is 15
A forms a proportion, 28x4=112 and 3x4=12.
B does not form a proportion.
Hi,
-5x = -115
-115/-5 = 23
-5 × 23 = -115
The answer is 23
Hope this helps! :)
Step-by-step explanation:
100% = $70.99
there is a discount of 25%.
that means 75% (100 - 25) of the original price remains.
the equation to get any x% amount of a 100% total is simply
x% amount = 100% total amount × x/100
25% = 70.99 × 25/100 = $17.75
