n(s)= 5+4+4=13

n(e)= red + blue

=5+4

=9

so, p(e) = n(e)/n(s)

p(e)= 9/13

=0.69

it's your answer

Step-by-step explanation:

according to bodmas .... brackets come first so the numerator (2-7)²+5 is 2-7= -5² hence -25 +5
so the answer to the numerator becomes -25 +5 which is -20
so u get -20/3 which when simplified u will obtain -6 and 2/3

Solve for x 2/x+1/2=3/4

charle [14.2K]

X in the equation 2/X+1/2=3/4 equals 8

We can find this by first finding the common denominator of 1/2 and 3/4 which is 2/4.

Then we can ask, 2/4+?=3/4

By asking this question we can find out that 2/4+1/4=3/4

With this new knowledge we can now ask 2/?=1/4. Which will lead us to the answer 8.
