Answer:
3 1/2 or 3 test tubes
Step-by-step explanation:
1/4 = 2/8
It will exact fit 3 1/2, but if you need a whole number than 3.
1 test tube can be fully filled.
1/4 can only go 7/8 once
Theorem
In a triangle, the measure of an exterior angle equals the sum of the measures of its two remote interior angles.
x + y = z
4n - 18 + n + 8 = 133 - 6n
5n - 10 = 133 - 6n
11n = 143
n = 13
z = 133 - 6n = 133 - 6(13) = 133 - 78 = 55
Answer: C. 55
23 x^ 4 y^ 7
