Answer:
(a). $20,000
(b). The estimate will be lower than the actual amount.
Step-by-step explanation:
We have been given that Michael saves $423 dollars a month for college.
(a). We know that 1 year equals 12 months.
4 years = 4*12 months = 48 months.
Since we are asked to find the estimated amount of money Michael will save in 4 years, so we will estimate both quantities as:
Therefore, Michael will save approximately $20,000 in 4 years.
(b).
The estimate will be lower than the actual amount as we rounded $423 down $23 to nearest hundred that is $400 and rounded 48 up 2 to nearest ten that is 40.
Therefore, the estimate will be lower than the actual amount.
6a. n=600
6b. n=6
6c. n=1/6
6d. n=50
7. The answer is -55.8 or 7c.
All I had time to do but might edit answer later.
Answer:
12x
Step-by-step explanation:
We require the lowest common multiple of 4x, 3 and 2x
the lowest common multiple of 4, 3 and 2 is 12
the lowest common multiple of x and x is x
Combining the two gives lowest common multiple of 12x
Multiplying through by 12x gives
72x - 9 + 4x = 6 + 60x ← no fractions
