Answer:
Two solutions were found :
w = 1
w = -4
Step-by-step explanation:
w =(-3+√25)/2=(-3+5)/2= 1.000
or:
w =(-3-√25)/2=(-3-5)/2= -4.000
Answer:
60 child tickets and 72 adult tickets
Step-by-step explanation:
Let x denote the number of child tickets sold and y the number of adult tickets sold. The problem involves solving the following system of linear equations; x+y=132 and 5.2x+8.6y=931.2. Using technology to solve this simultaneous equation yields; x= 60, y =72
Answer:
Step-by-step explanation:
Given
Required
Find x
First, we calculate the amount paid in terms of the cost price.
This is calculated using:
Express as decimal
Open bracket
So, we have:
and
---- given
Equate both

Solve for x
Let unit cost of one rake be : r
Given : Total number of volunteers = 12
Given : Each pair of gloves cost $8.00
⇒ Cost of 12 pair of gloves for 12 volunteers = (12 × 8) = $96
Given : The gardener spends a total of $300 on both rakes and gloves
⇒ Cost of 12 rakes + Cost of 12 pair of gloves = $300
⇒ 12r + 96 = 300
⇒ 12r = 204
⇒ r = 17
<u>Answer</u> : Cost of one rake is $17
13 times with a remainder of three
