Answer:
Step-by-step explanation:

Remember the multiply and add rule or improper fractions. To convert from a mixed number to an improper fraction, one must multiply the number part of the mixed number by the bottom (denominator) on the fraction. Then one must add that to the numerator (top) of the fraction. Since 7 is 1 less than 8, then one would have to multiply 15 by 1, and add it to 11, to get the value on top of
The value would be;
Answer:
-8 1/2 ft / min
Step-by-step explanation:
X = second diver rate
1 1/2 X = -12 3/4
3/2 X = - 51/4
X = - 51/4 * 2/3 = - 102/12 = -8 1/2 ft / min
Answer:
34 degrees and 56 degrees
Step-by-step explanation:
As the two given angles are complementary,
2x-10+3x-10=90
5x-20=90
5x=90+20=110
x=110/5=22
x=22
Now each angle
2x-10=2*22-10=34 degrees
and
3x-10=3*22-10= 56 degrees
