Answer:
5 felt pads.
7 cards.
Step-by-step explanation:
Remark
- The total number of items is 12
- So let the felt sheets be x
- Let the cards = y
Equations and Solution
x + y = 12
Now the price is 7.75 that she has to pay for the 12 items. She wants to come back with 0 dollars.
0.5x + 0.75y = 7.75 Multiply this equation by 2
x + 1.5y = 15.50 write the first equation underneath and subtract.
<u>x + y = 12</u>
.5y = 3 Divide by 0.5
y = 3/0.5
y = 7
So she can get 7 cards.
x + y = 12
x + 7 = 12
x = 12 - 7
x = 5
So she can buy 5 felt pads.
Answer:
A
Step-by-step explanation:
Our angle is -312 degrees, but because angles on the unit circle are always periodic and repeat every 2π or 360°, that means if we add a certain multiple of 360 to -312, we should get an angle with the terminal side pointing in the same direction.
Let's add 360 to -312:
-312 + 360 = 48°
Thus, the answer is A.
Answer:
Options A and B
i.e., A. 4(3
) and B.
Step-by-step explanation:
Like radicals are similar to like terms.
For example,
x, 2x, -10x, 
, 7.3x are like terms.
are some more examples of like terms.
Similarly, like radicals are:
etc.
Hence, from the given options, like radicals to 
are:
A. 
and B.
B+1 is not possible to be 0
for this b+1≠0, b ≠ -1
-1 is the value
<h3>
Answer: D) 5</h3>
Reason: It's the largest exponent
When a polynomial is written in standard form like this, the term with the largest exponent is written first, then the next largest and so on. So in cases like this, we simply need to look at the left-most term; however, this may not always be the case as your teacher could easily mix up the terms to make sure you're paying attention.
This is considered a quintic polynomial due to the degree of 5.
