Answer:
Division property get you to the quick solution
Solution: 3.4
Step-by-step explanation:
5*(x - 2) = 7
Dividing both sides by 5
5*(x -2)÷5 = 7÷5
x - 2 = 1.4
Adding 2 on both sides, we
x -2 + 2 = 1.4 + 2
x = 3.4
Hope you will understand the concept.
Thank you.
Answer:
it is 79.4 ft.
Step-by-step explanation:
u just have to round until it gets to one decimal
Total length of the string = 
yard
Length of string used for craft = 
of total length of string
= of
= 
= 
yard
Length of the string left after use = Total length of the string - Length of string used for craft
Length of the string left after use = 
=
Reducing it to the lowest term, we get
=
yard
Therefore, the length of string left is yard.
Answer:
(g+f)(x)=(2^x+x-3)^(1/2)
Step-by-step explanation:
Given
f(x)= 2^(x/2)
And
g(x)= √(x-3)
We have to find (g+f)(x)
In order to find (g+f)(x), both the functions are added and simplified.
So,
(g+f)(x)= √(x-3)+2^(x/2)
The power x/2 can be written as a product of x*(1/2)
(g+f)(x)= √(x-3)+(2)^(1/2*x)
We also know that square root dissolves into power ½
(g+f)(x)=(x-3)^(1/2)+(2)^(1/2*x)
We can see that power ½ is common in both functions so taking it out
(g+f)(x)=(x-3+2^x)^(1/2)
Arranging the terms
(g+f)(x)=(2^x+x-3)^(1/2) ..
