First, convert 3 into a fraction with denominator 8.
(3 pizzas)(8/8 pizzas)=24/8 pizzas
Then, divide 24/8 pizzas by 2/8 pizzas per 1 person.
(24/8 pizzas)(2/8 pizzas/person)
Dividing by a fraction is the same as multiplying by the reciprocal:
(24/8)/(2/8)=(24/8)×(8/2) the 8s cancel and you are left with 24/2=12
3 pizzas will feed 12 people.
Since both equal y, they have to equal each other. set them equal to each other as -3x+1=2x-4. add four to both sides to get -3x+5=2x. add -3x to both sides to get 5=5x. divide both sides by one to get x=1.
P parallel to q
So m<1 =m <3
3x=105
x=35
tell me if you don't understand
3x + 6 + x + 2 = 180
4x = 180 - 8
4x = 172
x = 43
A = 3x + 6 = 3×43 + 6 = 129 + 6 = 135
