The reciprocal is the flipped value so it will be11/9
Let cheese wafers = x
chocolate wafers = y
we know they bought 20 total packets so x+y = 20, this can be re-written as x = 20-y
cheese wafers cost 2, so we have 2x
chocolate wafers cost 1, so we have 1y, which is just the letter y
so we know 2x + y = $25
replace x with x=20-y to get:
2(20-y)+y = 25
distribute the parenthesis:
40-2y +y = 25
combine like to terms to get:
40-y = 25
subtract 40 from each side"
-y = -15
divide both sides by -1
y = 15
chocolate wafers was y so they bought 15 chocolate wafers
cheese wafers was x, so they bought 20-15 = 5 cheese wafers
using the substitution method was the easiest way to isolate one of the variables in order to find the solution.
Answer:
Length of beads altogether in the necklace = 3.75 cm
Step-by-step explanation:
Length of the beads used in a necklace = 
cm
Number of beads used in the necklace = 3
Therefore, length of beads in the necklace = Length of each bead × Number of beads used
= 
= 
= 3.75 cm
Length of the beads altogether in the necklace = 3.75 cm
Put them in order then find the median and if there are two or more divided by how many are in the middle
