Answer:
x=6
Step-by-step explanation:
7x+12=9x
simplify
subtract 7x from both sides
12=2x
divide both sides by 2
x=6
An exponential function is the function f(x)=ab^x, <span>where a≠0, </span>b>0 and b<span> ≠1, and </span>x is any real number. Important property of the exponential function is that it grows by common factors over equal intervals. In the real world exponential functions can model <span>populations, electricity, temperatures, bank accounts, credit payments, compound interest, ...</span>
-2x+9. just distribute a -1
Four tenths would be 0.4 so it would be less than 4
The answer si:
- 16 servings - 6 oz of salmon
- 24 servings - 9 oz of salmon
- 80 servings - 30 oz of salmon
- 100 servings - 37.5 oz of salmon
1 roll is 8 servings and it is also made of 3oz of smoked salmon. That means that 3oz of smoked salmon is needed fo 8 servings.
Now, let's made some proportions:
<u>16 servings:</u>
3 oz is for 8 servings, how much oz is for 16 servings:
3 : 8 = x : 16
x = 3 · 16 ÷ 8 = 6 oz
<u>24 servings:</u>
3 oz is for 8 servings, how much oz is for 24 servings:
3 : 8 = x : 24
x = 3 · 24 ÷ 8 = 9 oz
<u>80 servings:</u>
3 oz is for 8 servings, how much oz is for 80 servings:
3 : 8 = x : 80
x = 3 · 80 ÷ 8 = 30 oz
<u>100 servings:</u>
3 oz is for 8 servings, how much oz is for 100 servings:
3 : 8 = x : 100
x = 3 · 100 ÷ 8 = 37.5 oz
