1/2x + 3 = 2/3x + 1....multiply everything by the common denominator of 6
3x + 18 = 4x + 6
3x - 4x = 6 - 18
-x = - 12
x = 12 <====
multiplying by the common denominator will get rid of the fractions
1. Distribute
7i × 5 + 7i × -9i
2. Simplify 7i × 5 to 35i
35i + 7i × -9i
3. Simplify 7i × -9i to -63ii
35i - 63ii
4. Use the Product Rule
35i - 63i^2
5. Use the Square Rule
35i - 63 × -1
6. Simplify 63 × -1 to -63
35i - (-63)
7. Simplify brackets
35i + 63
8. Regroup terms
63 + 35i
We have been given that the biggest bowl of mashed potatoes ever made weighed pounds and was created at the Iowo State Fair in 2005. The biggest deep dish pizza ever made was in Chicago in 1998. It weighed a whopping pounds.
To find how much pizza weighs more than bowl of mashed potatoes, we will subtract weight of mashed potatoes from weight of pizza.
Now we will convert into scientific notation as:
Therefore, the pizza weighs pounds more than the bowl of mashed potatoes.
