Answer:
Let x represents the week and y represents the seashells
As per the statement:
Dora has 10 seashells and plans to add 2 shells every week.
"2 shells every week" means 2x
⇒y = 10 + 2x
It is also given, Jerri has 4 seashells and plans to add 5 shells every week.
"5 shells every week" means 2x
⇒ y = 4 + 5x
The system of equation would be used:
y = 10 + 2x
y = 4 + 5x
Since, the girls have the same number of seashells
⇒
Subtract 4 from both sides we get;
Subtract 2x from both sides we get;
Divide by 3 both sides we have;
x = 2 weeks.
Therefore, the number of weeks would it be before the girls have the same number if seashells is, 2 weeks.
To solve this, we are going to set up a simple rule of three: If 20% are 48 cars, 100% how many cars will be:
Now, we can express this as a proportion ans solve for
:
We can conclude that there are 240 cars in the parking lot.
0.15 with dash on top and the dash means its a repeating decimal and a repeating decimal is a decimal that repeats itself in this case it would be 0.1515151515 and so on
Not gonna lie i have no idea LOL
Answer:
The greatest ammount of picnic baskets you could make is 30 with an extra 12 granola bars left over, but it depends on how many people are going to eat from one picnic pasket. For example..say there were two people sharing each basket, you would make 15 picnic baskets with 12 leftover. The number would be 15 baskets because each person sharing the picnic basket together would each get 1 sandwich and 1 granola bar.
