Answer:
No
Step-by-step explanation:
If a ordered pair is a solution for an equation, then it will satisfy the equation. That is, after substituting the x and y values in the equation, both sides of the equation will be same.
Here 29 ≠ 45.
So, (4,7) is not a solution

Answer:
20
Step-by-step explanation:
To find this, we need to figure out what 1/5 is as a decimal
5/5 = 1, so 5 groups of 1/5 equals 1
Multiply this by 4, 20 groups of 1/5, or 20/5 = 4
Now we confirm this
1/5=0.2
4/0.2=20
So it is true

Answer:
gabrielas age is 15
Step-by-step explanation:
Let Gabriela's age be x, then Kelvins age is 2x
12 years ago, Gabriela's age was x - 12 and Kelvin's age was 6(x - 12)
i.e. 6x - 72 = 2x - 12
4x = 60
x = 60/4 = 15
Therefore, Kelvin's age is 2(15) = 30 years old
