Use a system of equations to solve this problem. Hunter needs 10 oz of a snack mix that is made up of seeds and dried fruit. The
motikmotik

The hunter should purchase 3 ounces of seeds and 7 ounces of dried fruit to satisfy the scenario.

<u><em>Explanation</em></u>

x= the amount of seeds and y= the amount of dried fruit.

As the hunter needs total 10 ounces of a snack mix , so the first equation will be..

x+y= 10 .....................................(1)

Now the seeds cost $1.50 per ounce and the dried fruit costs $2.50 per ounce. And the mixture costs $2.20 per ounce, so the second equation will be:

1.50x+2.50y= 2.20*10\\ \\ 1.50x+2.50y= 22.........................................(2)

According to the substitution method, we will isolate y from the first equation as y= 10- x

Now we will substitute this y= 10- x into the second equation in place of y

1.50x+2.50(10-x)= 22\\ \\ 1.50x+25-2.50x =22 \\ \\ -1.00x = 22-25 \\ \\ -1.00x= -3\\ \\ x= 3

Plugging this x=3 into the equation y= 10- x , we will get...

y= 10-3 =7

So, the hunter should purchase 3 ounces of seeds and 7 ounces of dried fruit to satisfy the scenario.

Please help with this one​
Lilit [14]

Answer:

x = 7, y = 16

Step-by-step explanation:

The consecutive sides of a kite are congruent, thus

2x + 5 = x + 12 ( subtract x from both sides )

x + 5 = 12 ( subtract 5 from both sides )

x = 7

And

y - 4 = x + 5, that is

y - 4 = 7 + 5 = 12 ( add 4 to both sides )

y = 16
