255 times 3 which gets you an estimate start point
next you start at 83 then 3 more is 85 then 3 more is 87. those are your numbers
4/16 do not receive treatment
which is 25%
25% do not receive treatment
Answer:
Real numbers are all the rational numbers such as -7 and 4/3 and all irrational numbers. Real numbers are used mainly in counting and are used in measurement which is always present in real-world situations. These numbers help us to quantify things around.
Answer:
4/15 or 4:15
Step-by-step explanation:
We know a ratio is basically for everyone of this we will have a "x" number of the other for example
1:4 or 1:33
In order to solve this, all our data should be in the same unit
so in this case let's work with minutes
48min : 3hr after converting 3hr to min we get...
48min : 180min
now we can simplify this to make this visually easier im going to use a fraction format
48 24 12 4
------- ÷2 ---------- ÷2 -------- ÷3 ----- I can not simplify any further
180 90 45 15
So my answer is 4/15 or 4:15
2x + y = 350
x + 2y = 475
3x + 3y = 825
x + y = 275
x = 275 - y
(plug back into first equation)
2(275 - y) + y = 350
550 - 2y + y = 350
550 - y = 350
-y =-200 or y = $200 (dog)
therefore, x = $75 (cats)
Check
2(75) + 200 = 350
75 + 400 = 475
HAPPINESS! :)
