40 garments need to be dry cleaned for the two companies to have the same cost.
<h3>
Linear equation</h3>
Linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
Let f(x) represent the cost for dry cleaning at Company 1. Hence using the points:
- (5, 115.25) and (15, 155.75)
Let g(x) represent the cost for dry cleaning at Company 2. Hence using the points:
- (5, 45.25) and (15, 105.75)
For the cost to be the same:
4.05x + 95= 6.05x + 15
x = 40

V ( pyramid ) = 1/3 B h = 1/3 · 1 · 2 = 2/3 in³
120 : 2/3 = 120 · 3/2 = 180
Answer: The largest number of pyramids she can make is B ) 180

First solve the congruence 
. Euclid's algorithm shows
330 = 25 * 13 + 5
13 = 2 * 5 + 3
5 = 1 * 3 + 2
3 = 1 * 2 + 1
=> 1 = 127 * 13 - 5 * 330
=> 127 * 13 = 1 mod 330
so that 
is the inverse of 13 modulo 330. Then in the original congruence, multiplying both sides by 127 twice gives
Then any integer of the form 
is a solution to the congruence, where 
is any integer.
Answer:
in the last one 3+4+4×15=67
in the first if we see there are three shapes if we divide 45/3 so the value of each shape is 15
in the second there are two bananas and one shape as we know the value of shape so 23-15=8 as there are two bananas so the value of each banana is 4
in the third there are two clocks and one banana as we know the value of banana so 10-4=6 as there are two clocks so the value of each clock is 3
from above
shape=15 banana=4 and clock =3 pitting in the equation gives us the value of 67
