Answer:
1/5 or 20%
Step-by-step explanation:
This problem can be easily solved by finding the probability of her picking one matching pair to leave in the suitcase (which results in pulling out exactly two matching pairs)
For the first sock, it does not matter what sock she picks.
For the second sock, there is only 1 out of the 5 socks left that would match the first one picked. Therefore, the probability that she pulls out exactly two matching pairs is 1/5 or 20%
Answer:
x=5/16
Step-by-step explanation:
Let's solve your equation step-by-step.
4x(−4)=−2−(−3)−6
Step 1: Simplify both sides of the equation.
4x(−4)=−2−(−3)−6
−16x=−2+3+−6
−16x=(−2+3+−6)(Combine Like Terms)
−16x=−5
−16x=−5
Step 2: Divide both sides by -16.
−16x
−16
=−5/−16
x=5/16
can I be the brainiest please!!
You can break 98 into 2 49's. Hopefully, we know that 49 is 7 * 7, so 98 is 7 * 14. The correct answer is 14. :)
Answer:
5
Step-by-step explanation:
To determine the cost of each item, we need to set up equations. From the problem statement, we have three unknowns so we need three equations. We set up equations as follows:
let x cost of small pizzas
y cost of soda
z cost of salad
two small pizzas, a liter of soda, and a salad cost $14
2x + y + z = 14
one small pizza, a liter of soda, and three salads cost $15
x + y + 3z = 15
three small pizzas, a liter of soda, and two salads cost $22
3x + y + 2z = 22
Solving for x, y and z, we will have:
x = $ 5
y = $ 1
z = $ 3
