Yes beacuse that means it would be 32 years old

If we replace the 3 in the ratio with a 25 (which is a reasonable age for a parent), it means that the child would have to be about 17 years old. (The ratio would be 20:16.666667 to stay equal to 3:2) Therefore, it is not possible.

Marat540 [252]

Golfer had the lowest number of strokes per hole is Alicia  = 4.

Step-by-step explanation:

We have , Three different golfers played a different number of holes today. Rory played 999 holes and had a total of 424242 strokes. Alicia played 181818 holes and had a total of 797979 strokes. Rickie played 272727 holes and had a total of 123123123 strokes. We have to find , Which golfer had the lowest number of strokes per hole :

Rory:

Number of strokes per hole = $\frac{424242}{999} = 425$

Alicia:

Number of strokes per hole = $\frac{797979}{181818} = 4$

Rickie:

Number of strokes per hole = $\frac{123123123}{272727} = 451$

∴ Golfer had the lowest number of strokes per hole is Alicia  = 4.

Identify a possible first step using the elimination method to solve the system and then find the solution to the system. 3x - 5

Nastasia [14]

Answer:

see explanation

Step-by-step explanation:

Given the 2 equations

3x - 5y = - 2 → (1)

2x + y = 3 → (2)

Multiply (2) by 5 will eliminate y when added to (1), that is

10x + 5y = 15 → (3)

Add (1) and (3) term by term

(3x + 10x) + (- 5y + 5y) = (- 2 + 15)

13x = 13 ( divide both sides by 13 )

x = 1

Substitute x = 1 into (2) for corresponding value of y

2 + y = 3 ⇒ y = 3 - 2 = 1

Solution is (1, 1)
