Answer:

PR = 16

simplify

2x = 30

x = 15

PR = 15 + 1 = 16

SR = 15 - 3 = 12

Tyrell katy and lucy were eating grapes. Tyrell ate twice as many grape as katy, and lucy ate half as many grapes as katy. If ka

Vesnalui [34]

Answer:

21 grapes.

Step-by-step explanation:

We have been given that Tyrell ate twice as many grape as Katy. Lucy ate half as many grapes as Katy. Katy ate 6 grapes. We are asked to find the total number of grapes that all of them eat in all.

First of all, we will find twice of 6 grapes to find number of grapes eaten by Tyrell.

$\text{Grapes eaten by Tyrell}=2\times 6$

$\text{Grapes eaten by Tyrell}=12$

Now, we will find half of 6 to find number of grapes eaten by Lucy.

$\text{Grapes eaten by Lucy}=\frac{6}{2}$

$\text{Grapes eaten by Lucy}=3$

$\text{Grapes eaten by them in all}=6+12+3$

$\text{Grapes eaten by them in all}=21$

Therefore, the three of them eat 21 grapes in all.
