You'd need to convert feet into inches first. 2 feet is 24 inches. then add the other three inches. Juan's dog is 27 inches tall and Peters dog is 9 inches tall.
your fraction would be 27/9 which simplifies to 3.
Juan's dog is 3 times bigger than Peters!
The percentage decrease is 60% decrease because it changed by 81 and 81 is 60% of 135
0.5 / 100 * X = 3
X = 3 * 100 / 0.5 = 300 / 0.5 = 600
Answer:
z = 21 ; y= 16
Step-by-step explanation:
first of all we have to isolate a variable.
In second expression we can obtain:
3y = 2z+6
y = 2/3 z + 2
now we have to substitute this value in the first equation and solve it
8(2/3z+2)-5z = 23
16/3z + 16 -5z = 23
16z +48 - 15z = 69
z = 21
now we have to substitute z in the second equation:
y = 2/3 (21) +2
y = 14+ 2 = 16
y = 16
