?=40/3
Step-by-step explanation:
Answer:
x = 5.75
Step-by-step explanation:
4^(x+7) = 8^(2x-3)
But; 4^(x+7) = 2^2(x+7)
8^(2x-3) = 2^3(2x-3)
2^2(x+7) = 2^3(2x-3)
Since the bases are the same;
2(x+7) = 3(2x-3)
2x + 14 = 6x -9
14 + 9 = 6x - 2x
23 = 4x
x = 23/4
<u>x = 5.75</u>
Answer:
B. Add/subtract the same quantity from both sides.
in this case, it would be adding <em>x</em><em> </em>to both sides to simplify the equation.
<span>First, let’s check for the given:
Shirts on the rack = 240</span>
Medium size shirts = 40% of 240
<span>With the following given, we can now solve for the total
number of shirts on the rack that are size medium.
So, in order to solve for the problem, we multiply 40% to 240:</span>
<span>The decimal equivalent of 40% is 0.4.
240 shirts * .4 = 96 shirts</span>
Therefore, out of 240 shirts on the rack, there are 96 shirts
on the rack that are size medium.
To add, the number or ratio that represents a fraction
of 100 is called a percentage.
