Answer:
His error is adding 10 and 2/3 before multiplying by a(age of the tree)
Step-by-step explanation:
The sum of 10 and two-thirds of that tree's age, in years, is equal to 50.
Correct equation
Sum = addition (+)
two-thirds = 2/3
The tree's age = a
10 + 2/3a = 50
2/3a = 50 - 10
2/3a = 40
a = 40 ÷ 2/3
= 40 × 3/2
= 60
a = 60 years
Javier writes the equation
(10 + two-thirds) a = 50
(10 + 2/3)a = 50
(30+2/3)a = 50
32/3a = 50
a = 50 ÷ 32/3
= 50 × 3/32
= 150/32
a = 150/32
His error is adding 10 and 2/3 before multiplying by a(age of the tree)
Answer:
6
Step-by-step explanation:
Answer:
4/25
Step-by-step explanation:
12 divided by 3
72 divided by 3
Greatest Common Divisor:
3
So 12/72 simplifed would be 4/25 and the GCD would be 3.
This problem is easy the correct choice for it will be B.
Answer: 7788.50
Solving steps:
P = 7400, R = 10.5%, T = 6
F = P + P rt
P = 7400
R = 10.5%
T = 6
F = 7400 + 7400rt
7400 x (12 + 6 x 0.105/12
7400 x (12 + 0.63)/12
7400 x 12.63/12
93462/12
15577/12
15577/2 0.01
7788.50
Answer: 7788.50
