Answer:
Javier's equation is not correct because the variable "a" should be multiplied by only and then added to
Step-by-step explanation:
Let
a------>is the tree’s age in years
we have that
-------> Javier's equation
we know that
The equation that represent the situation is equal to
Solve for a
Multiply by both sides
Javier's equation is not correct because the variable "a" should be multiplied by only and then added to
I think it’s (3,4) the third answer
Answer: b
Step-by-step explanation:
In the last question, you wrote on a second equation "13x ...." kkk
Let's go:
We have to check each one answer in the following system:
x - 2y = 7
3x + 7y = 8
I can use the substituition method to solve this system...
x = 7 + 2y
3x + 7y = 8
3(7 + 2y) + 7y = 8
21 + 6y + 7y = 8
13y = 8 - 21
13y = -13
y = -1
x = 7 + 2.(-1)
x = 5
Finally, the correct answer is the second one (letter b).
