9 + 9 = 18
42 - 18 = 24
24 / 2 = 12
the length is 12 inches
Answer:
One rule for dividing fractions is the rule where instead of doing 13/43, you can do 13 times 1/43.
Step-by-step explanation:
Yeah
Answer:
a) 137.9°
b) 12.2° (please refer to explanation because I didn't know what to round to)
Step-by-step explanation:
1a) A supplementary angle will equal 180°, so you must subtract 42.1 from 180
180-42.1 = 137.9
1b) A complementary angle will equal 90°, so you need to use the expression given and add an x for the other part of 90°
8x-20+x = 90
9x-20=90
9x=110
x=12.2
Answer:
0.8 or .8
Step-by-step explanation:
multiply the top and bottom by 10
so 8/10=80/100
to get the decimal form, just divide 8 by 10 and it should give you 0.8
This is assuming that the question laid out the sequence of a calculation.
4y x 3y + z = 100
12y^2 + z = 100
