Given:
Yamir is twice as old as Pato.
In three years, the sum of their ages will be 30.
Pato's current age is represented by [tex]a[/tex].
To find:
The equation that could be used to correctly solve for [tex]a[/tex].
Solution:
We know that, Pato's current age is represented by a, then
Yamir's age = [tex]2a[/tex]
After three years,
Pato's age = [tex]a+3[/tex]
Yamir's age = [tex]2a+3[/tex]
In three years, the sum of their ages will be 30.
[tex](a+3)+(2a+3)=30[/tex]
[tex](a+2a)+(3+3)=30[/tex]
[tex]a+2a+6=30[/tex]
Therefore, the correct option is 2.

The image of the point ( 4 , 5 ) by translation ( 0 , -4 ) is
9514 1404 393
Answer:
P'(4, 1)
Step-by-step explanation:
Add the translation values to the point coordinates.
P(4, 5) ⇒ P'(4 +0, 5+(-4)) = P'(4, 1)
Eva buys online tickets to a play for her family. Each ticket costs $45.00 and there is a fee of $17.99
Answer:

A baseball player hits a ball towards a 20-foot wall 400 feet away. The path of the ball is modeled by the function, f(x)=-0.002(x-220)^2 +86, where x is the distance of the ball from the batter and f(x) is the height of the ball.
Based upon the function, f(x), what is the maximum height of the ball will reach?
At how many feet from the batter will the ball be at its maximum height?
Will the ball clear the wall?

In a 30 · 60 · 90 triangle, the smallest side is x, the hypotenuse is 2x and the longer leg is x√3. So, in our 30 · 60 · 90, we have the hypotenuse is 6, so 6 ÷ 2 = 3 to give us the smallest leg (in this case is y), so y = 3. Because the longer leg is √3 · the smallest leg, 3√3 is the longest leg.
x = 3√3
y = 3

Each card in a set of cards has one of the letters adventures. The cards are shuffled what is the probability of drawing a vowel?
Answer:
7/11 if its not that then its 64% Hope this helps!
Step-by-step explanation:
Since there are 11 letters in the word mathematics, and 7 consonants, you have the fraction 7/11. however, if it's required as a percentage, We know that
7/11
is the same as
7÷11
Then using
Long Division for 7 divided by 11
gives us
0.636
Converting our number to a percentage:
0.636×100
is 64% rounded to the nearest 10. Rounding to the nearest hundredth, you'd get 63.64%

Yes, it is a triangle and it is unique.
Yes, it is a triangle, but it is not unique.
No, it does not make a triangle.
Answer:
No It Is Not A Triangle
Step-by-step explanation:
To be a triangle the 2 shorter sides have to add up greater than the longest side, 1.4+1.8=3.2 which is not grater than 4.5

Samir buys T-Shirts for $10 each and markups the price by 35%. Samira claims that Samir has to mark each shirt up by $3.50.
Is she correct?
Answer: she is correct
Step-by-step explanation:
35% in decimal form is 3.50
(-15)-(-3) =
(1-7)+(+5) =
(+5) x ( +6 ) =
(+18 ) + ( +6)
(9)+( 8 ) =
(+10)-(+1) =
( +4 ) x ( 3 ) =
( 12 ) + ( +4 ) =
(+6) + (6)
(+11)-(7) =
(-8) x ( +2 ) =
(+15) + ( 3 ) =
(*12 ) + ( 4) =
(8) - ( +2) =
(-7) x ( -5 ) =
(-10 ) = (-2) =
Answer:
(-15)-(-3) = -12
(1-7)+(+5) = -1
(+5) x ( +6 ) = 30x
(+18 ) + ( +6) 24
(9)+( 8 ) = 17
(+10)-(+1) = 9
( +4 ) x ( 3 ) = 12x
( 12 ) + ( +4 ) = 16
(+6) + (6) 12
(+11)-(7) = 4
(-8) x ( +2 ) = -16x
(+15) + ( 3 ) = 18
(*12 ) + ( 4) = 4
(8) - ( +2) = 6
(-7) x ( -5 ) = 35x
