HW- Tuesday December 16- Algebra

For today, use algebra to find the intersecting point for the following equations. Complete these in your journal. You can verify them at this site:

https://www.desmos.com/calculator


y =  9X  +  7  and y = 3X - 11

y =  7X - 12   and  y = 2X + 13

y = -12X  + 4  and y = - 3X  - 76

y = 7x - 8   and y = 4X +  12


Bonus: This will have two points where they intersect
y = x     and y = 16/x

HW- Tuesday December 2 - SEVENTH Grade

1.) Mario wants to buy some Cheerios at Target.  He can buy a small box for $2.50, a large box for $3, and a Family box for $4.

The small box is 16 ounces of cereal, the large box is 24 ounces of cereal, and the family box is 32 ounces of cereal.

How much is each ounce of cereal for each box?  How much money is saved per ounce by buying the family size box instead of the small box?


2.)  Adolfo noticed the price of a 20 oz., bottle of Coke changes from place to place.  At Target, it costs $1.  At Granado's it costs $1.50 for the same bottle.  At the movie theater it costs $3 for the bottle.  How much is each ounce of Coke for each of the locations?  How much more is EACH ounce of Coke at the movie theater than at Target and at Granados?
