Answer:
3/14
Step-by-step explanation:
There are 14 marbles, 5 are yellow, 6 are blue, and 3 are pink. You have a 5/14 chance to get a yellow marble, a 6/14 chance to get a blue marble, and a 3/14 chance to get a pink marble.
I hope that this helps :)
<span>A) -12x - y = 6
</span><span>
B) 17x + y = 4
</span>Adding both equations:
5x = 10
x = 2
Since x =2
<span>17x + y = 4
</span>
17 * 2 + y = 4
y = 4 -34
y = -30

Explanation:</h2>
Here we have to solve a system of linear equations in three variables. Let:
x: Cost of pens
y: Cost of pencils
We know that:
- Bailey buys 2 pens and 6 pencils and spends a total of $7.00. So:
- Jeremiah buys 3 pens and 5 pencils and spends a total of $7.50. So:
Multiplying eq1 by 3 and eq 2 by -2:
Then adding these two resultant equations:
How much will Maggie spend to purchase 4 pens?
Each pen costs $1.24, so 4 pens will cost:
