Step-by-step explanation:
Total fat in mixture is 8x+15y100 pints.
Explanation:
In a mixture of x pints of 8% butterfat, we have 8x100 pints of butter
and in y pints of 15% butterfat, we have 15y100 of butterfat.
Hence total fat in mixture is 8x+15y100 pints.

4/6=t/(t+1)
Answer:
Each friend ate 4 tacos.
Step-by-step explanation:
"4 of his friends ate s tacos" is unclear. I assume it should be
"4 of his friends ate s tacos each."
total tacos = 2 + 4s = 18
4s = 16
s = 4
His four friends ate a total of 16 tacos, each friend eating 4 tacos.
Ricky's reason, i.e., that 6s = 18, is incorrect.
6s = 4s+2s, where 4s is what his friends ate in total.
That implies that Ricky ate 2s tacos, instead of 2 tacos. If 2s = 2 then s = 1, but then 6s ≠ 18.
Step-by-step explanation:
14×5=70
8×8=64
(3/70) + (5/64)
= (3×64)+(5×70)
----‐------------------
70×64
= (192+350)/448
=542/448
= 271/224
