ten granola bars and 12 bottles of water cost $23. 5 granola bars and four bottles of water cost $10. how much do one granola ba

pishuonlain [190]

Answer:

2.15

Step-by-step explanation:

Let g= cost of granola bars

b = cost of bottles of water

10g+12b =23

5g +4b = 10

I will solve this system by elimination

Multiply the second equation by -2

-2(5g +4b) = -2*10

-10g -8b = -20

Now we add this equation to the first equation to eliminate g

-10g -8b = -20

10g+12b =23

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

4b = 3

b = 3/4

A bottle of water = $.75

Now we need to find g

5g+4b =10

5g +4(.75) = 10

5g +3 = 10

Subtract 3 from each side

5g +3-3 = 10-3

5g =7

Divide by 5

5g/5=7/5

g = 7/5

g = 1 2/5

g =1.40

We want the cost of one bottle of water and 1 granola bar

1g + 1b

1.4+.75

Many families in California are using backyard structures for home offices, art studios, and hobby areas as well as for addition

Natalija [7]

Answer:

-0.75

Step-by-step explanation:

To get the z score we have to use this formula

Z = X-mean/standard deviation

X = 2300

Mean = 3200

The standard deviation = 1200

When we plug these values into the z formula above, we have:

2300-3200/1200

= -900/1200

= -0.75

the z-score for a backyard structure costing $2,300 is therefore -0.75
