X + 3x = 12
(Or 4x=12)
the first x is the number of girls then the second x is the girls times 3, which is how many boys there are.
For this case, the first thing we must do is define a variable.
We have then:
n: number of days.
We now write the explicit formula that represents the problem.
We have then:
an = 4n + 15
Where,
15: crunches the first day
4: increase the number 4 each day
Answer:
An explicit formula for the number of crunches Abbie will do on day n is:
an = 4n + 15
Answer:
P(y≤4) = 0.629
Step-by-step explanation:
you can see in attachment.
2 and 3 are both parallel because both slopes are m=3/5, which equal slopes-parallel lines
Answer:
c
Step-by-step explanation:
mass will never change only weight will as weight is dependent on gravitational field strength
