This one is very simple.
create a simple equation to find out
15 = 12 + x
subtract 12 from each side
x= 3
the missing number is 3
or, to be even simpler, take the total, subtract the total from the number you know and the difference is the missing number.
hope I helped
ALSO, we can check going down vertically. 3 + 10 =13. this is the total listed at the bottom.
8 x 7 x 6 x 5 x4 x3 = 20,160 ways
Answer:
8,6,7,8,9,10
Step-by-step explanation:
y=x+4x+5x=10
X=16/3 or 5.33333 based on the fact that the angles are congruent
Thank you.
7^5 times 4^5 is equivalent to (7 times 4)^5, which is 28^5. You could either leave your answer in this format or evaluate 28^5: 17210368.
(153^2)^7 is best done using the rule of exponents (x^a)^b = x^(ab). Multiply the exponents 2 and 7 together: (153^2)^7 = 153^(2*7) = 153^14.
(10^5)(4^5) has two factors, both of which have the exponent 5. We can rewrite this expression as (10*4)^5, which equals 40^5. No, this is not equal to 14^5!
