Answer:
- partial products: 0.25, 1.5, 0.50, 3
- Zoe spent $5.25 on apples
Step-by-step explanation:
The partial products are apparently derived by multiplying parts of each value on either side of the decimal point:
1.5 × 3.50 = (1 + 0.5)(3 + 0.50) = 1×3 + 0.5×3 +1×0.50 +0.5×0.50
= 3 + 1.5 + 0.50 + 0.25 . . . . . partial products
Their sum is ...
3 + 1.5 + 0.50 + 0.25 = 5.25
Zoe spent $5.25 on apples.
•divide both sides by 3
•take the square root of both sides
•subtract 2 from both sides
(used the Khan academy hints so this is 100% correct)
The letter (Z) is the symbol used to represent integers. An integer can be 0, a positive number to infinity, or a negative number to negative infinity.
