Answer:
. The sweaters cost $10 or less each. We graph it on a number line at 10 and use a filled in dot pointing towards zero for less than.
Step-by-step explanation:
Mrs. Smith buys 3 sweaters (represented by 3s) and 2 jeans (represented by 2j) for a total of at most $120. We don't know the total but we do know she couldn't spend more than $120.
We write .
We know the jeans cost $45 each, so j=45. We substitute,
We solve for s by subtracting 90 to the other side and dividing the result by 3.
.
The sweaters cost $10 or less each.
5 is 10% out of 50, just do 100% of 50 which is 50 therefore 10% of 50=5!

Answer:
The signal would have experienced aliasing.
Step-by-step explanation:
Given that:
the bandwidth of the signal 
= 36MHz
= 36 × 10⁶ Hz
The sampling frequency 
= 36 × 10⁶ Hz
Suppose the sampling frequency is equivalent to the bandwidth of the signal, then aliasing will occur.
Therefore, according to the Nyquist criteria;
Nyquist criteria posit that if the sampling frequency is more above twice the maximum frequency to be sampled, a repeating waveform can be accurately reconstructed.
∴
By Nyquist criteria, for perfect reconstruction of an original signal, i.e. the received signal without aliasing effect;
Then,
∴
The signal would have experienced aliasing.
Use distributive property
4x - 4 = 12 - 4x
8x = 16
X = 2
