Answer:
The answer is 36 adults and 88 children.
Step-by-step explanation:
The two equations are:
x+y=124 and 5x+3y=444
Using substitution method:
5x+3(124+x)=444
5x+372-3x=444
2x=72
x=36
5(36)+3y=444
180+3y=444
3y=264
y=88
It’s gonna be radical 10x/ 4x.
Answer:
r = (-1)
Step-by-step explanation:
Firstly simplify the brackets,
; -3(1 + 6r) = -3 - 18r
then substitute on the bracket with the simplified form,
; -3 - 18r = 14 - r
then move the values with (r) to one side and the other ones without (r) to the other side
; -3 - 14 = 18r - r
; -17 = 17r
then divide both sides by 17,
; -1 = r
Hence...r = -1
Answer: 48 square feet.
Step-by-step explanation:
So you can say 12x12 is 144. You know there are 4 sides. They will be all twelve as this is a square.
The perimiter is 12 plus 12 plus 12 plus 12 equals 48 square feet
