Answer:
Jonathan has 18 chairs in the class room and Marie used 29 blocks.
Step-by-step explanation:
a) In Jonathan's classroom there are red chairs, yellow chairs and blue chairs.
There are 3 red chairs
rc = 3
There are 3 times as many yellow chairs as red chairs
rc * 3 = yc
3*3 = 9
yc = 9
There are 3 fewer blue chairs than yellow chairs
yc - 3 = bc
9 - 3 = 6
bc = 6
How many chairs are there in Jonathan's classroom?
rc + yc + bc
3 + 9 + 6
3+9 = 12+ 6 = 18
Marie made 4 stacks of wooden blocks
The first stack was 6 blocks tall
fs = 6
The second stack was 6 blocks taller than the first
fs + 6 = ss
6+6 = 12
ss = 12
The third stack was 8 blocks shorter than the second stack
ss - 8 = ts
12 - 8 = 4
ts = 4
The last stack was 3 blocks taller than the third stack
ts + 3 = ls
4 + 3 = 7
ls = 7
fs + ss + ts + ls
6 + 12 + 4 + 7
6 + 12 = 18 + 4 = 22 + 7 = 29
