You multiply 750 and 5 to get the answer to the sugar. 750×5=3750 so the answer would be 3,750 grams of sugar.

Solve 3^x − 2 = 3^7<br><br> A. 2<br> B. 5<br> C. 7<br> D. 9

Vikki [24]

Answer:

C) 7

Step-by-step explanation:

3^x−2=2187

Step 1: Add 2 to both sides.

3^x−2+2=2187+2

3^x=2189

Step 2: Solve Exponent.

3^x=2189

log(3x)=log(2189) <<Take log of both sides

x*(log(3))=log(2189)

x= log(2189)/log(3)

x=7.000832
