Answer:

The steps have been shown in the solution below

Step-by-step explanation:

(3x+1)^{2} - 2(3x+1)=(3x+1)(3x-1)

9x^{2} +6x+1 -6x-2= (3x+1) (3x-1)\\\\9x^{2} -1=(3x+1)(3x-1)\\\\(3x+1)(3x-1)=(3x+1)(3x-1)\\

LHS=RHS Hence, proved.

Convert 7.7km into miles if 1.6 km = 1 mile
Lemur [1.5K]
This is a simple equation.  

The equation is y = 1.6x  with y being the miles and x being the kilometers.

Lets plug the kilometers in.

Y=1.6(7.7)

1.6 *  7.7 = 12.32

12.32 miles is  equal to 7.7 kilometers

HOWEVER

There are about .6 miles in a kilometer, so if you typed this wrong I don't know.  

It is still the same concept.

Y = .6x

Y = .6(7.7)

.6 * 7.7 =  4.8

In this case there are 4.8 miles in 7.7 kilometers

Answer:
amount of nuts = 2 pounds
amount of dried fruit = 4 pounds

Explanation:
We are given that x is the amount of nuts and y is the amount of dried fruit.
We are also given that:
1- Hunter needs to make 6 pounds of trail mix. This means that:
x + y = 6
This can be rewritten as:
x = 6 - y .........> equation I
2- x costs $4 per pound, y costs $3.5 and Hunter can spend a total of $22. This means that:
4x + 3.5y = 22 ..........> equation II

Substitute with equation I in equation II and solve for y as follows:
4x + 3.5y = 22
4(6-y) + 3.5y = 22
24 - 4y + 3.5y = 22
24-22 = 4y-3.5y
2 = 0.5y
y = 4 pounds

Substitute with y in equation I to get the value of x as follows:
x = 6-y
x = 6-4
x = 2 pounds

Hope this helps :)
