Answer:
2+3=5
Step-by-step explanation:
You asked for an equation, I gave one to you.
Answer: 16⅔ yds by 25 yds
Step-by-step explanation:
Let x be the length of 3 fence sections
Let y be the length of 2 fence sections
A = xy
3x + 2y = 100
y = 50 - 1.5x
A = x(50 - 1.5x) = 50x - 1.5x²
dA/dx = 50 - 3x
0 = 50 - 3x
3x = 50
x = 50/3 = 16⅔ yds
y = 50 - 1.5(16⅔) = 25 yds
#10 ) 6/x = 5/11 OR 6/x = 9/19.8
5x = 66 9x = 118.8
x = 13.2 x = 13.2
#11 ) original photo is 5 inches by 7 inches, multiply that , = 35 ( area of original photo )
new photo is "3 times larger" so 5 become 15 and 7 become 21 , multiply that which gives you 315 (area of enlarged photo )
take the enlarged photo's area divided by the original photo's area which gives you 9
#12 ) 6/8 = x/12
72 = 8x
9 = x
#13 ) set equal to find segment TR : 4/10 = 6/x
4x = 60
x = 15
then find the perimeter of triangle by P = a + b + c
P = 10 + 12 + 15
P = 37
