X+y=15
2x+3y=37
15-x=y
2x+3(15-x)=37
2x+(45-3x)=37
2x-3x+45=37
-1x=-8
x=8
x is the amount of bikes, so there are 8 bikes. 8x2=16.
37-16=21
21/3=7
There are 7 tricycles.
Answer:
(a)6 feet
(b)24 sections
Step-by-step explanation:
(a)We are required to find the length of the Giant Sub.
If each section is 1/3 of a foot long and there are 18 equal parts.
Length of the Giant Sub =
Length per Section X Number of Sections
= 1/3 X 18 = 6 feet
(b)If each section is 1/4 of a feet long
Length of the Giant Sub =
Length per Section X Number of Sections
6= 1/4 X Number of Sections
Number of Sections =6 X 4 =24 sections
