Madelyn has x nickels and y dimes, having a maximum of 15 coins worth no
less than $1 combined. At least 2 of the coins are nickels and at least 9 of the
coins are dimes. Solve this system of inequalities graphically and determine

Answer:
2 nickels, 9 dimes
Step-by-step explanation:
When there are a number of overlapping shaded areas on the graph, I find it convenient to use the reverse of the inequalities. That makes the unshaded area the solution space. Here, the vertices of the triangular solution space are ...
(2, 9), (2, 13), (6, 9)
Any of the grid points within (or on) this triangle is a possible solution. One of them is (2, 9) corresponding to 2 nickels and 9 dimes.
__
Three solutions are shown:
(x, y) = (2, 9), (3, 10), (4, 11)

find the exact value of x.
Answers
Answer:
9*√3
Step-by-step explanation:
The exact value of Sin60 = √3/2
Sin(60) = opposite side/ hypotenuse
hypotenuse = 18
√3/2 = x / hypotenuse
√3 / 2 = x / 18 multiply by 18
18 √3 /2 = x divide by 2
9 √3 = x

Did you sleep with a comfort object as a child? Do you still? No
need to stuff that teddy bear from your infant years in your closet the
next time you have a guest over—the odds are good that he or she has
a comfort object, too. A study conducted by Sleepopolis and
OnePoll reported that 34% of adults still sleep with a stuffed animal,
blanket, or other sentimental object, according to a survey of a random
sample of 100 adults. A similar study, based on a random sample of 80
children reports that 75% of children sleep with a comfort object.
Do these data provide convincing evidence that the proportion of adults
who sleep with a comfort object is less than the proportion of children

back up and begin with a running start.
Answers
Answer: Make the ramp longer
making the ramp shorter and making the ramp steeper would be the same, and backing up wouldn't really help
Pickle should make the ramp longer in order to be successful.
Option A is the correct answer.
What is a ramp?The ramp refers to a sloped surface that connects a lower level to a higher level.
We have,
- A longer ramp will provide a more gradual slope, which will make it easier for the cart to move up the ramp.
- If the ramp is too short,
The slope will be too steep and it will be difficult to push the cart up.
- Making the ramp steeper will also make it more difficult to push the cart up.
- Starting with a running start may provide some initial momentum, but it will not address the underlying problem of the ramp being too short.
Thus,
Pickle should make the ramp longer in order to be successful.

Find value of x
I need it fastttttt
Answers
Answer:
x=1
Step-by-step explanation:
you have to put x on one side. send -10 to the other side. Add 10 on both sides to delete 10.
7x-10+10=3x-6+10
now it leaves you with 7x=3x+4
Now you have to send 3x to the other side because you are solving for x. subtract both sides by 3x to delete 3x on the other side.
7x-3x=3x-3x+4
how it leaves you with 4x=4
now you divide both sides by 4
4/4x=4/4
Hence, x=1
Answer:
standard form: 4x - 4 = 0
factorisation: 4(x - 1) = 0
solutions: x = 4/4 = 1
therefore, x is 1
