We have that
<span>If (5x-4+13x=5) --------------> then x=1/2
Step 1
</span>let's substitute the value of x = (1/2) in the expression [5x-4+13x] and verify its result
5*(1/2)-4+13*(1/2)
(5/2)-4+(13/2)
(5-4*2+13)/2----------> (5-8+13)/2=10/2=5
then
5=5-----------> <span>the value of x = (1/2) satisfies equality</span>
Answer:
6
Step-by-step explanation:
I used a calculator. :)
4 1/2 = 9/2
5/9 x 9/2 = 45/18
<E = 180 - 14 - 45 = 121
so
<D = 180 - 27 - 121 = 32
answer
<D = 32
