It looks like it could be D.
Step-by-step explanation:
Answer:
a
Step-by-step explanation:
6x-12/10
2(3x-6/5)
Consecutive odd integers means that the equation is
(x)+(x+2)+(x+4)+(x+6)+(x+8)=-65
add like terms
5x+20=-65
subtract 20 from both sides
5x=-85
divide both sides by 5
x=-17
so x+2=-15
x+4=-13
x+6=-11
x+8=-9
so they are (-9,-11, -13, -15, -17)
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.
