Express 4 less than a number is actually easy.
X will be our number.
But it won't be just X, it would be X squared or x^2.
So you do... (x^2)-4.
(The 4 is what you subtract).

Answer:

d = 1/2

Step-by-step explanation:

5/6 = 1/3 + d

~Find common denominators

5/6 = 2/6 + d

~Subtract 2/6 to both sides

3/6 = d

~Simplify

1/2 = d

Help I will gave u brilliant answer please help​

Answer:

a) 15/8   b) 25/18

Step-by-step explanation:

a) First bring all the fractions to a common denominator (I'm going to use 8th's). 5/8 is already simplified, 1/2=4/8, and 3/4=6/8. Then, simply add the numerators and leave the denominator:  \frac{5+4+6}{8} =\frac{15}{8}

Since this can not be simplified any further, your final answer is 15/8.

b) Start by bringing all the fractions to a common denominator (for this problem, we'll use 18th's). 2/3=12/18, 1/6=3/18, and 5/9=10/18. Then just add all the numerators and leave the denominator the same: \frac{12+3+10}{18} = \frac{25}{18}

Since this cannot be simplified further either, your final answer is 25/18.

Hope this helps! :)
