Answer:
Step-by-step explanation:
Be glad to help, but I need the expression, please.
make the decimal into into 3
then
3/10×3 =9/10=0.9
There are 7 nickels, 9 dimes, and 16 quarters. If you do the math 7 nickels equals 35 cents, 9 dimes equal 90 cents, and 16 quarters equals $4.00, which all adds up to $5.25. Also the numbers follow the rules because 7 is two less than nine and 16 is 9+7.

Answer:
300 bags of wheat
Step-by-step explanation:
We can get the answer by using<em> algebraic expressions. </em>If 1,200 bags means a 20% decrease in the yield from 2005, then it is<em> 80% of the yield in 2005</em>.
Let's solve.
Let x be the number of bags yield from 2005.
We can say: 1,200 is 80% of x
1,200 = 80% of x
1,200 = 0.80(x)
x =
<em>x = 1,500</em>
The number of bags yield from 2005 is 1,500.
Let's check.
Let x be the decrease in yield.
1,500 x 20% = x
1,500(0.20) = x
x = 300
The 20% decrease in yield is equal to 300 bags of wheat.
1,500 - 300 = 1,200 bags
The answer is correct.
