Answer:

 0.3453 grams

Step-by-step explanation:

to find the amount of days in 6 weeks, you multiply 6 and 7 which will get you 42. Then 42/4 is 10.5. This means it will go through 10 full half-lifes. you divide 500 by 2 10 times and 0.3453 g is the closest answer.

Help, please! ASAP!!!​
Diano4ka-milaya [45]

Answer:

Angle A is 77°

x = 3

AC = 13

Step-by-step explanation:

Angles A, B and C MUST add up to 180°.  If Angle C is 26°, then the sum of A and B and 26° = 180°.  In other words, A+B = 180° - 26° = 154.

Since A and B are equal, A = B = 154°/2 = 77°

Since this triangle is isosceles, sides AC and BC are equal.  Thus,

7x - 8 = 3x + 4, or

4x = 12.  Then x = 3.

Since AC = 7x - 8, and x = 3, AC = 7(3) - 8 = 21 - 8 = 13

How do I find the solution

You're trying to get x by itself.

add 4 to both sides
2x (greater/equal sign) -2

divide 2
x (greater/equal sign) -1

on the graph number the small lines. put a closed circle on 1 and shade to the left.
