What is an inequality?An inequality is an inequation separated by <,>≥,≤. the relationship between two values that are not equal is defined by inequalities. Inequality means not equal. Generally, if two values are not equal, we use “not equal symbol (≠)”. But to compare the values, whether it is less than or greater than, different inequalities are used.
Given here: Jake's class has 24 students and she is to choose a group which is a multiple of 5
Thus the possible multiples of 5 between 1 and 24 are
5,10,15,20
Therefore all these multiples are less than 21
Hence, The Number of classmates in his group is less than 21

Answer: Choice A) $0.20
=======================================================
Explanation:
The store bought the batch for $100, and sold that same batch for $150. The profit of the entire batch is 150-100 = 50 dollars.
Divide this over 250 to get 50/250 = 0.20 dollars.
Their profit is $0.20 per pastry (ie 20 cents per pastry).
-------
You can think of it like this
50 dollar profit = 250 pastries
50/250 dollar profit = 250/250 pastries (dividing both sides by 250)
0.20 dollar profit = 1 pastry
That last equation tells us one pastry yields a profit of $0.20 or 20 cents.
Answer:
$0.20
Step-by-step explanation:
If the purchased is $100 for 250 pastries, then 1 ipastry at purchase is:
$100=250
? = 1
1×100/250 = $0.40 ( at purchase)
Then when resold, the profit is:
if 250 pastries= $150
1 pastry=?
$150× 1/ 250= $0.60
s0, the profit will be $0.60 - $0.40 = $0.20

I remember doing the last question.
If you recall, x = 29
Just plug 29 into x for each angle
A = 3(29) = 87
B = 2(29) + 1 = 59
C = 29 + 5 = 34
Answer:
The value of angle C is 34°
Step-by-step explanation:
2x+1°+x+5°+3x° = 180° { the sum of angle of triangle is 180°}
or, 6x + 6° = 180°
or, 6x = 180° - 6°
or, x = 174°/6
or, x = 29°
now,
value of angle C = x+5°
= 29°+5°
= 34°

Step-by-step explanation:
Given:
Total amount spend = $36
Cost of each slice = $2.25 per slice
Number of slices = x
Find:
