The variables x and y very directly. Use the values to find the constant of proportionality K then write equation that relates t
o x and y. Write any fraction in simplest form. Y equals 20 and X equals 12
1 answer:
Answer:
k=5/3
Step-by-step explanation:
The variables x and y vary directly. Given that, y = 20 and x = 12
We can write it as :
y=kx
Where k is constant of proportionality
Put the values of x and y
20=12k
k = 20/12
k = 5/3
So, the value of the constant of proportionality is 5/3.

Answer:
1. 43/36
2. 1/2
Step-by-step explanation:
1. 7/9 + 5/12
= LCM of 9 and 12 is 36
= 28/36 + 15/12
= (28 + 15) / 36
= 43/36
2. 21/24 - 3/8
= LCM of 24 and 8 is 24
= 21/24 - 9/24
= (21 - 9) / 24
= 12/24
= 1/2
Answer:
m<1 = 97
m<2 = 83
m<3 = 112
m<4 = 68
m<5 = 112
m<6 = 68
m<7 = 97
m<8 = 83
m<9 = 97
m<10 = 83
m<11 = 112
m<12 = 68
m<13 = 112
m<14 = 68
m<15 = 97
m<16 = 83
Step-by-step explanation:
2/5 = 40%
3/10= 30%
1/2= 50%
1/10= 10%
so it's 1/2
73℅ of 58
= (73/100) × 58
= (73×58)/100
= 4234/100
= 42.34
