3. Alfonso's friend Dani tells Alfonso that her bloodhound, Ol' Sniffy, lived to be 14.
Based on what you know, do you think this was because:
Alfonso didn't use a good estimation method,
Dani doesn't remember Ol' Sniffy's age correctly, or,
Ol' Sniffy lived an unusually long time?
Justify your answer.
It looks like this question wants you to figure out your answer by looking at the chart to see if it looks reasonable.
The first answer doesn't seem to fit the plot so we know that, that inst right. The second one seems like it could work with the question but we dont have enough info to rule it in or out. The third one seems really off because alot of the dogs on the chart lived to be 14 if they where a good weight.
Answer 2: Dani doesn't remember Ol'Sniffy's age correctly, seem like the best fit.
Hope this helped!

Simplify: 2/5y−4+7−9/10y
Answer:
-1/2y + 3
Step-by-step explanation:
2/5y - 4 + 7 - 9/10y
= (2/5y - 9/10y) + (-4 + 7)
= (2/5 - 9/10) y + 3
= (4/10 - 9/10) y + 3
= -5/10y + 3
= -1/2y + 3

Valery spent 15 of her money buying 8 pencils and 2 markers. Each marker cost twice as much as each pencil. She used 58 of her remaining money buying more markers. How many markers did Valery buy in all?
The total number of markers did Valery buy in all will be 25 markers.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Valery spent 15 of her money buying 8 pencils and 2 markers. Each marker cost twice as much as each pencil.
Let 'x' be the cost of pencils and 'y' be the cost of markers. Then the equations are given as,
8x + 2y = 15 ...1
y = 2x ...2
From equations 1 and 2, then we have
8x + 2(2x) = 15
8x + 4x = 15
12x = 15
x = $1.25
Then the cost of the marker is given as,
y = 2(1.25)
y = $2.25
She used 58 of her remaining money to buy more markers. Then the number of markers she bought is given as,
⇒ $58 / $2.5
⇒ 23.2
The total number of markers did Valery buy in all is given as,
⇒ 23 + 2
⇒ 25
The total number of markers did Valery buy in all will be 25 markers.

a= (-3a) + 4 help me plz solve
Answer:a=2
Step-by-step explanation:
Simplifying
a = 3a + -4
Reorder the terms:
a = -4 + 3a
Solving
a = -4 + 3a
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-3a' to each side of the equation.
a + -3a = -4 + 3a + -3a
Combine like terms: a + -3a = -2a
-2a = -4 + 3a + -3a
Combine like terms: 3a + -3a = 0
-2a = -4 + 0
-2a = -4
Divide each side by '-2'.
a = 2
Simplifying
a = 2
