Answer:
2a + 4b = 44
a+b=15
Step-by-step explanation:
Call a the number of chickens, b the number of horses
We have: 2a + 4b = 44
a + b = 15
=> 2(a+b) = 30
<=> (2a + 4b) - (2a + 2b) = 14
2b = 14
=> b = 7
=> a = 8
So 8 chickens, 7 cows.
Answer:
397
Step-by-step explanation:
write an equation:
x = logan
y = marcus
z = janet
x = 2y
z = 1/3y+8
y = 243
x = 2 * 243
x = 486
z = 1/3 * 243 + 8
z = 89
logan = 486 contacts
marcus = 243 contacts
janet = 89 contacts
486-89 = 387
logan has 397 more
