So you do the recipical and multipy 7 by 2 and your fraction is 14/24 and simplify which you get 7/12
When you have to put the percent over 100 the you would simplify it.
36 x 24=864 whole poster
5 x 12=60 cut part
864 - 60= 804 part that remains
;)
Answer:
Step-by-step explanation:
Substitute y = x-4 in the first equation.
Distribute -2 in the expression.
Because we only want to find the value of x.
Therefore the answer is -4.
The extraneous solution of startroot 4 x 41 endroot = x 5 will be A. -8.
<h3>What is an extraneous solution?</h3>
It should be noted that an extraneous solution simply means a root of a transformed equation which isn't part of the original equation.
✓4x + 41 = x + 5
Square both sides
4x + 41 = x² + 10x + 25
x² + 6x - 16
x(x + 8) - 2(x + 8) = 0
x + 8 = 0
x= 0 + 8 = 8
