What is the answer to v-10 equals -3?
-7
Simplify 4 square root of 6 divided by square root of 30 reduce first?
4 x V¯6 ---------- V¯30 Simplify V¯6 to V¯3 and V¯2; Simplify V¯30 to V¯10 and V¯3 4 x V¯3 x V¯2 ------------------- V¯10 x V¯3 Simplify V¯10 to V¯5 and V¯2 4 x V¯3 x V¯2 ---------------------- V¯5 x V¯2x V¯3 Cross out V¯3 and V¯2 from both sides. 4 ------- V¯5 Multiply the numerator and denominator by V¯5 (You cannot have a radical in the denominator). 4 x V¯5 --------- <---- Final Answer 5
If the average of three numbers is V If one of the numbers is Z and another is Y what is the remaining number?
#1="a" #2="b" #3="c" (a+b+c)/3=V if a=Z and b=Y, Z/3+Y/3+c/3=V Therefore: c/3=V/(Z/3+Y/3) c=3*V/(Z/3+Y/3) I've encountered that on my GRE review. The given are: A. ZY - V B. Z/V - 3 - Y C. Z/3 - V - Y D. 3V- Z - Y E. V- Z - Y if the 3rd missing letter is X, then maybe (I just guessed, so I'm not sure): z/3+y/3+x/3=V x/3=V -z/3 -y/3 3(x/3)=(V -z/3-y/3)3 cancel all corresponding 3's and times 3 to V x= 3V-z-y the answer is D.
What is v divided by 4 minus 3 equals 5?
Trying to find v: v/4-3 = 5 v/4 = 8 (+3 both sides) v = 32 (*4 both sides)
