Answer:
2.75
Step-by-step explanation:
(y-5)6+15–5y=5
(y-5+5)6-6+15-15–5y=5-6-15+5
y-5y=-11
-4y/-4=-11/-4
y=2.75
161 1-foot tiles.
EXPLANATION:
To find how many tiles we need,
We must find the area of the kitchen.
To find the area, you multiply
length x width
In this question,
the length is 14
the width is 11.5
14 x 11.5 is 161.
So 161 1-foot tiles to cover the kitchen.
Hope this helps! Have a gud day!
Answer:
x=36/7-3
Step-by-step explanation:
see this is for nerds so i can't really show you cause i don't know how to but put this on your test and u will get it right
Radius = 1.25cm
81cm3 / 20 = 4.05 cm3 per cone
V cone = πr^2 (h/3)
So then 4.05 = π(1.25)^2 (h/3)
Then h/3 = .825 and then
h = 2.475 cm
This is easy! Just use the point-slope form:

Plug in the values:
-1 - 4 = m(2 - (-3))
Combine like terms
-5 = 5m
Divide both sides by 6
m = 5/-5 or
m = -1
