Answer:

n=5-2p

Step-by-step explanation:

STEP 1: <em>Rewrite the equation as  3 n + 6 p = 15 .</em>

3n+6p=15

STEP 2: <em>Subtract  6 p  from both sides of the equation.</em>

3n=15-6p

STEP 3: <em>Divide each term by  3  and simplify.</em>

n=5-2p

Please answer this correctly without making mistakes
SCORPION-xisa [38]
First, multiply 1,127 & 1 by 2
1127 x 2 = 2254
1 x 2 = 2

so that’s 2,254 cups & 2 fl. ounces
since 8 fl. oz. make a cup, and we only have 2, the answer stays as it is

2,254 cups & 2 fl. ounces
