Break up chain with AND statement:
(2/3)t - 1 < t + 7 AND <span>t + 7 ≤ -2t + 15
left side, we solve for t
</span>
<span>(2/3)t - 1 < t + 7
(2/3)t - t < 7 + 1
(-1/3)t < 8
t > -24
right side, we solve for t</span>
<span>t + 7 ≤ -2t + 15
t + 2t </span><span>≤ 15 - 7
3t </span><span>≤ 8
t </span><span>≤ 8/3
So our answer would be </span>
t > -24 AND t <span>≤ 8/3
as an interval, this is
</span>-24 < t <span>≤ 8/3
or in interval notation
(-24, 8/3]</span>
The correct answer is option 2.
3 = 0
x - a = 0
x = a
x + b = 0
x = -b
We do not multiply any of these values by 3 because in a way, 3 is acting as another "zero" of the equation. Though, as shown above, it does not equal 0, it still does not apply to any of the other equations solved above.
Hope this helps!! :)
Answer:
3x=18
Step-by-step explanation:
We want to get the variable x by itself.
Since we see a -3 with the 3x, we want to move the 3 to the other side of the equal sign by adding 3 to both sides of the equal sign.
3x - 3 = 15
3x - 3 + 3 = 15 + 3
Then we get:
3x + 0 = 18
3x = 18

Step-by-step explanation:
Answer:
22
Step-by-step explanation:
Use the trapezoid area formula.
A = (b1 + b2) / 2 * h
Plug in the values.
A = 3 + 8 / 2 * 4
A = 11 / 2 * 4
A = 44/2
A = 22
