A monument made of a certain number of rows consisting of cube-shaped bricks starts with a row of 34 bricks. The
row above has 31 bricks, the row above that has 28 bricks,
and so on such that each row has three fewer bricks than the
row below it. A portion of the monument is shown below.
Later a student notices that the total number of bricks used
in the monument is just enough to create the brick floor of a
rectangular patio that is one layer of bricks, seven times as long
as it is wide. (No bricks are broken to make the floor.) How
many rows of bricks does the monument have?

step-by-step explanation:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
