Answer:

S = 9.9

Step-by-step explanation:

First, multiply by -3 to remove fractions:

so:

S - 38.4 = -28.5

Take all values to one side by adding 38.4 to both sides

S = 9.9

Joseph and Wendy were catching tadpoles. At first Wendy caught nine times three more than Joseph caught. Joseph was upset and re

Dmitriy789 [7]

Answer:

Joseph caught 7 tadpoles

Step-by-step explanation:

Let the number of tadpoles caught by Joseph be x

The number of tadpoles Wendy caught will be ;

9(x + 3)

After Joseph was upset, he released half of Wendy’s tadpole and then six times as many as Joseph caught swam away leaving Wendy with only three tadpoles left;

Hence, mathematically;

9(x + 3)/2 - 6x = 3

Multiply through be 2

9(x + 3) - 12x = 6

9x + 27 -12x = 6

9x -12x = 6-27

3x = 21

x = 21/3

x = 7

AB ← → is tangent to circle O at point A. If m∠AOB = 72degrees what is m∠ABO ?

tatuchka [14]

Answer:

$m\angle ABO=18^o$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

If AB is tangent to circle O at point A

then

AB is perpendicular to AO (radius) and Triangle ABO is a right triangle

$m\angle ABO+m\angle AOB=90^o$ ----> by complementary angles in a right triangle

substitute the given value

$m\angle ABO+72^o=90^o$

$m\angle ABO=90^o-72^o=18^o$
