To solve this question, first cross multiply
Let ? = x
4/9 = x/81
4(81) = 9(x)
Simplify.
81 x 4 = 324
324 = 9x
Isolate the x, divide 9 from both sides
324/9 = 9x/9
x = 324/9
x = 36
4/9 = 36/81
36 is your answer
hope this helps!
Answer:
19 girls
Step-by-step explanation:
Since there are 3 more girls than boys, 35-3=32
32/2=16
Now add back the 3
16+3=19
Supplementary angles are 180 in total, so to find the answer you do 180-10, which equals 170. The answer is 170
Divide -10 in 15 = -0.666666666
32 cm 3
