Answer:
Step-by-step explanation:
3y+5y=8y
8y=7(divide 8 in both sides to get y)
y=7/8
x+2y=3...but we already know the value of y, so substitute 7/8 to y
x+2(7/8)=3
x+14/8=3
x=3-14/8
=1.25
The square root of 78 is a number which when multiplied by itself results in 78. The square root of 78 is denoted by √78. 78 can be expressed as 78 = 2 × 3 × 13. Hence, on simplifying square root of 78 is written as √78
so the least number is root 78 , 9 , 10
Answer:
n = 27
Step-by-step explanation:
14n = 11n + 81 (Given)
14n - 11n = 11n - 11n + 81 (Subtraction Property of Equality)
3n = 81 (Simplify)
(Division Property of Equality)
n = 27 (Simplify)
Substituting <em>x</em> = 0 directly gives the indeterminate form 0/0, so you can use l'Hopital's rule (and you'll have to do that twice):

The limand is continuous everywhere, so you can plug in <em>x</em> = 0 to get 36•1/2 = 18.
