Answer:
x=1 or x=16
Step-by-step explanation:
3/4x = 12 or 0.75x = 12
3/4x/3/4 = 12/3/4 or 0.75x/0.75 = 12/0.75
x=12/1 / 3/4
x= 4/4
x = 1 or x = 16
Answer:
Cost to a rent a snorkel
, Cost on 10 rent snorkel 
Step-by-step explanation:
Given,
Tourist spend on rent snorkel and fin=
10 snorkel and 12 pairs of fin
Let the cost to rent a snorkel be =
x
and cost of a pair of fin is =y
x=3y (given condition)
Cost of a pair of fin= 
Cost of rent a snorkel
Total cost of a rent snorkel
=
Then put in some butter that will get you out
W^2 + w - 20 = (w + 5)(w - 4)
(w - 3) (w - 4) w^2 - 7w + 12
---------- * -------- = ------------------
(w + 5) (w - 4) w^2 + w - 20
Unit digit=y
tens digit=x
the number: 10x+y
We suggest this system of equations:
x+y=7
(10y+x)=(10x+y)+9
we solve it by substitution method.
x=7-y
10y+(7-y)=(10(7-y)+y)+9
9y+7=70-10y+y+9
9y+10y-y=70+9-7
18y=72
y=72/18=4
x=7-y
x=7-4=3
number=10x+y=10*3+4=30+4=34
solution: the number: 34
To check:
3+4=7
43=34+9
