4(3w+5)-2w=70
10w+20=70
10w+20-20=70-20
10w=50
10w/10=50/10
w=5
If there are 3 red blocks for every 5 blocks
if we multiple both numbers by 12 to make every 60 blocks we get:
36 red blocks every 60 blocks
since you have 36 and you only need 32 then yes you will have enough
Considering they are congruent
if 7x-19=2x+11
how much is 6x-8
7x-19=2x+11
7x=2x+30
7x-2x=30
5x=30
X=6
6x-8=
(6*X)-8=
(6*6)-8=
36-8=
28
therefore
BC= 28
2x+11
(2*6)+11
12+11
23
23+28+24=75
therefore the perimeter is 75
