3/5 * 9 1/2
1st way. Distributive property of multiplication.
3/5 * 9 = 3*9 / 5*1 = 27/5
3/5 * 1/2 = 3*1 / 5*2 = 3/10
Add the products:
27/5 + 3/10 = (27/5 * 2/2) + 3/10 = 54/10 + 3/10 = 57/10
Simplify: 57/10 into a mixed fraction 5 7/10
2nd way:
Converting the mixed fraction into an improper fraction and multiply.
9 1/2 = ((9*2)+1)/ 2 = 19/2
3/5 x 19/2 = 3*19 / 5*2 = 57/10
57/10 = 5 7/10
3rd way: We can use rounding of fractions to estimate the products.
3/5 * 9 1/2
9 1/2 can be rounded off to 10.
3/5 * 10 = 3*10 / 5
30 / 5 = 6 is the estimated product of rounding.
Answer: x= -56/9
Step-by-step explanation:
34+12x=3x-22
Subtract 12x from both sides
34=-9x-22
Add 22 to both sides
56=-9x
Divide -9 by both sides to get x alone
56/-9=x
So
x=-56/9
