Answer:
a=28/5 or 5.6
Step-by-step explanation:
2a/7=a-4
Multiple both sides of the equation by 7
2a=7a-28
Subtract 7a from both side
2a-7a=-28
Like Term
-5a=-26
Divide -5 from both side
a= 5.6
The number lines should show the weights the car seats are designed for in comparison the the weight of the 32lb child. The car seat made for children 30lb and lighter would not work because this child is 32lbs. Model this by placing a filled in circle at 30 and the arrow should face left. The seat for children between 15lbs and 40lbs and the seat designed for a child that is between 30lbs and 85lbs would work because the child is within these weight ranges. The number line for the seat for a 15lb-40lb child would have open circles at 15 and 40 with a line connecting the two points. The number line for a 30lb-85lb child should have filled in circles at these two point with a line connecting them.
Answer:
Step-by-step explanation:
The formula for determining simple interest is expressed as
I = PRT/100
Where
I represents interest paid on the amount invested.
P represents the principal or amount invested.
R represents interest rate
T represents the duration of the investment in years.
From the information given,
P = 10000
R = 4%
In the first year, the simple interest would be
I = (10000 × 4 × 1)/100 = $400
The compound interest in the first year is also $400
In the second year, the simple interest would be
I = (10000 × 4 × 1)/100 = $400
For the compound interest in the second year,
P = 10000 + 400 = $10400
I = (10400 × 4 × 1)/100 = $416
The table would be
Simple interest compound interest
1) 400 400
2). 400 416
Total 800 816
