25 for the first one
(-5-2=-7 -7x-3=21 21+4=25)
220 for the second one
(10x-2=-20 -20+(-2)=-22 -22x-10=220)
Given:
W(width) = (6L) - 9
L(length) = L
Equation:
2( [ 6L ] - 9) + 2 (L) = 150
= 12L - 18 + 2L = 150
= 12L + 2L = 150 + 18
=14L = 168
L = 168/14, so the length is 12. Let's check our work.
Width: 6(12) - 9 = 72 - 9 = 63
Length: 12
Since there are two lines of width and two lines of length:
2(12) + 2(63) = 24 + 126, which gives you a perimeter of 150 mm.
Hope this helped.
Answer:
There were 42 fewer students who chose Football than Hockey.
Step-by-step explanation:
Fraction of students who chose Hockey
= 1 - -
=
units = 21
1 unit = 42
No. of students who chose Football
= 2 units ()
= 84 students
No. of students who chose Hockey
= 3 units ()
= 126 students
Difference between no. of students who chose Football and Hockey
= 126 - 84
= 42 students
∴There were 42 fewer students who chose Football than Hockey.

Hey the first thing you do is reduce the numerator which is 648 to do that you have to mutiply the denominator by the factors 10,5,2,1. and then the partial quotient will add up as 50+20+10+1=81 :)
