Answer:
51÷41
Step-by-step explanation:
changing division form into multiplication by making its reciprocal
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

How many are there then the total amount
7^2 = 6^2 + 9^2 - 2(6)(9)cos(m)
-68 = 2(6)(9)cos(m)
cos(m) = -0.6296
m = arcos ( -0.6296)
m = 129.0 degrees
Answer:
yes! this is right as it matches the requirements
