2.)The sum of four consecutive odd
integers is -336. Set up an equation AND solve for all of the integers.
Two ways to approach this.
-336/4 = -84 making the 4 consecutive odd numbers -81, -83, -85 and -87.
Alternatively:
x + (x + 2) + (x + 4) + (x + 6) = -336
I'll let you solve for the answer.
Let x be an odd integer.
Then x + (x + 2) + (x + 4) + (x + 6) = -336
==> 4x + 12 = -336
==> 4x = -348
==> x = -87
Then the four consecutive odd integers are:
==> x = -87
==> x + 2 = -85
==> x + 4 = -83
==> x + 6 = -81
is this right?
Yes. Did they add to -336? Are they consective odd integers?
1+1=3
Yes, you are correct angel.
If x=2/3 and y=3/4 then 10xy=60
To solve for 10xy given x = 2/3 and y = 3/4, we can substitute these values into the equation:
10xy = 10 * (2/3) * (3/4)
First, multiply the numerator and denominator of the fractions:
10 * (2/3) * (3/4) = 20/3 * 3/4
To multiply fractions, multiply the numerators and denominators separately:
(20 * 3) / (3 * 4) = 60/12
Simplify the fraction:
60/12 = 5/1
Therefore, 10xy = 5/1, which simplifies to 5.
