Let the consecutive integers be x, x+1 and x+2.
By the question,
x+x+1+x+2 = 84
Or, 3x+3 = 84
Or, 3(x+1) = 84
Or, x+1 = 84/3
Or, x+1 = 28
Or, x= 28-1
.•. x= 27,,
Hence the smallest integer is 27,,
Answer:
26
Step-by-step explanation:
Let x be the first even integer
x+2 is the second even integer
x+4 is the third even integer
The sum of three consecutive even integers is 84
x+ (x+2) + (x+4) =84
Combine like terms
3x +6 = 84
Subtract 6 from each side
3x+6-6 =84-6
3x =78
Divide each side by 3
3x/3 = 78/3
x =26
The three integers are 26, 28,30
The smallest is 26

Answer:
B. Multiply f(x) by -1
Step-by-step explanation:
When we want to reflect over the x axis f(x) becomes -f(x)
so x^3 becomes -x^3
1 is a whole number, which would make the fraction a mixed fraction, and the 5 is the tenths place, so its 1 5/10
Answer:
3.75
Step-by-step explanation:
Set up the following ratio:
2400 watt-hours 1 day
------------------------- = ----------
9000 watt-hours x days
Then do criss-cross-apple-sauce:
x*2400=9000*1
And then solve for x:
2400x=9000
x=9000/2400
x=3.75
