cost of pistachios per pound = X+4

Cost of 2 pounds of pistachios=2X+8

Total cost=5X+8=48

5X+8=48

5X=40

X=8

cost of one pound almond is $8

Hailey rolls a twelve sided die, to choose a random number from one to twelve. What is the probability that the number hailey ro

Lemur [1.5K]

Answer:

7/12

Step-by-step explanation:

12 sided die has 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12 as the sides.

Two digits are 10, 11, and 12.

Even numbers are 2, 4, 6, 8, 10, and 12.

So two digits or even numbers are 2, 4, 6, 8, 10, 11, and 12. (7 total numbers)

P(Two digits or even) = 7/12

3. 17 = z -(-9) What’s the answer

kykrilka [37]

<h2>Answer:</h2>

17 + z -(-9)

+17 +17

(34) + (26)

z=60

<h2>Step-by-step explanation:</h2>

You need to solve for Z so we need to get z by itself so take 17 and add it to both sides because whatever is on the left side of the equal sign is always what you need to add 17+ 17 then 17+(-9) you get your answers then add those two up then you get z=60.

Consider the system of equations, y = f(x) and y= g(x), where

NARA [144]

Answer:

(x, y) = (3, 26)

Step-by-step explanation:

I like to solve systems of equations like this by graphing. A graphing calculator easily shows the solution for both x and y.

(x, y) = (3, 26)

As an alternative, here, the equations can be subtracted.

y = f(x)

y = g(x)

0 = f(x) - g(x) . . . . subtract the second equation from the first

0 = 11x -7 -(3x +17)

0 = 8x -24 . . . . simplify

0 = x -3 . . . . . . .divide by 8

3 = x

Now, we can substitute into either equation:

y = g(x) = 3(3) +17 = 26

The solution is (x, y) = (3, 26).
