Answer:
You included no options so I will list some of the various fractions and decimal that are equivalent to the fraction of days it was cloudy in April.
In fraction form, the value can be simplified to;
In decimal form, the value would be;
= 12 ÷ 30
= 0.4
Answer:
The inverse function of 3x - 4 is (x+4)/3. so a
Step-by-step explanation:
f(x) = 3x - 4
y = 3x - 4 replace f(x) with y
x = 3y - 4 replace x with y and y with x.
3y = x + 4 solve for y
y = (x+4)/3 replace y with f-1(x)
f-1(x) = (x+4)/3
Answer:
x = -13
Step-by-step explanation:
or, (4x-7)/x = (5x+6)/x
or, (4x-7) = (5x +6)
[the x gets cancelled when it comes to opposite side]
or, 4x-5x = 6+7
or, -x = 13
or, x = -13
Answera:The answer is 0.3333333333 repeated
Step-by-step explanation:5/6 is 0.8333333 repeated divided by 5/2 which is 2.5 which when divided is 0.333333333 repeated.
I'll be honest, this is a pretty interesting question. I've never seen anything like it before!
We can start off by making equations with the given. If there are 100 heads, that means that the total number of chickens and pigs combined is 100. Thus, we can form our first equation:
p + c = 100
('p' represents number of pigs, and 'c' represents number of chickens)
We also know that there are 270 legs total. Since chickens have 2 and pigs have 4, we can make the following equation:
2c + 4p = 270
I suppose the quickest way to solve for this equation is to use the subtraction method. Put the equations on top of each other:
2c + 4p = 270
c + p = 100
___________
Multiply the bottom equation by -2;
2c + 4p = 270
-2c -2p = 100
____________
"Add" these two equations together:
2c + 4p = 270
-2c -2p = -200
___________
2p = 70
Divide both sides by 2:
p = 35
Ah, finally. Now that we know that there are 35 pigs, input this variable into the first equation to find the number of chickens:
c + 35 = 100
Subtract:
c = 65
There are 35 pigs and 65 chickens
