Answer:

x=2

Step-by-step explanation:

You have to subtract 8 from both sides.

-5x+8=-2

-8 -8

----------------

-5x= -10

now divide both sides by -5.

x=-10/-5

(And two negatives make a positive.)

x=10/5

now you have to simplify 10/5

10/5 simplified is 2

so the answer is:

x=2

I hope this helps. :)

Nuts Galore sells a trail mix containing dried banana chips, roasted almonds, and chocolate chips that sells for $6.52 per pound

KengaRu [80]

Answer:

$x = 28$ ----- Banana

$y = 54$ ----- Almonds

$z = 18$ ---- Chocolate

Step-by-step explanation:

Let

$x \to$ banana

$y \to$ almonds

$z \to$ chocolate

So, we have:

$x + y + z = 100$ --- total used

$4x + 8y + 6z = 652$ -- i.e. 6.52 * 100 --- total sales from 100 pounds

$y = 3z$

Required

The number of pounds of each (i.e. x, y and z)

Substitute $y = 3z$ in $x + y + z = 100$

$x + 3z + z = 100$

$x + 4z = 100$

Make x the subject

$x = 100 - 4z$

Substitute $y = 3z$ in $4x + 8y + 6z = 652$

$4x + 8 * 3z + 6z = 652$

$4x + 24z + 6z = 652$

$4x + 30z = 652$

Substitute $x = 100 - 4z$

$4(100 - 4z) + 30z = 652$

$400 - 16z + 30z = 652$

Collect like terms

$- 16z + 30z = 652-400$

$14z = 252$

Divide by 14

$z = 18$

Substitute $z = 18$ in $x = 100 - 4z$

$x = 100 - 4 * 18$

$x = 100 - 72$

$x = 28$

To calculate y, we have:

$y = 3z$

$y = 3 * 18$

$y = 54$
