Ami purchases 27 T-shirts for a certain amount of money. Using m for the total amount of money in dollars that Ami spent on T-shirts, write an expression that represents how much one T-shirt costs
Answers
cost=total money
cost=number of tshirts times cost per tshirt
subsitute
m=27 times cost per shirt
to solve for cost per 1 shirt, divide both sides by 27
answer is 1 t-shirt costs
y = how much each t-shirt costs
m / 27 = y
because:
y x 27 = m
so the equation is:
>m/27 = y

Answer:
0.75 years.
Step-by-step explanation:
Assuming 360 days in a year or 12 months.
So, we get days each month.
In 9 months there will be = days
So, convert this period to years = = 0.75 years.
Hence, the answer is 0.75 years.

Answer:
x = 25
Step-by-step explanation:
From the given picture,
In ΔMLN,
m∠NML + m∠MLN + ∠LNM = 180°
61° + 39° + m∠LNM = 180°
100° + m∠LNM = 180°
m∠LNM = 180° - 100°
m∠LNM = 80°
If JK║MN and JN is a transverse intersecting these parallel lines at N and J,
∠LNM ≅ ∠LJK [Alternate interior angles]
(3x + 5)° = 80°
3x = 80 - 5
3x = 75
x = 25
