Answer:

52.5 ft.

Step-by-step explanation:

To find the area of a triangle you find the hight and length and multiply them which in this case would be 84. Then, you divide it by two because a triangle is half of a square which would equal 42. Lastly, you do the same with the left side of the triangle which would equal 10.5. then, you add 42 and 10.5 together and your answer is 52.5.

2x+2y=10 solve for x

irakobra [83]

Isolate the x. Note the equal sign. What you do to one side you do to the other.

Subtract 2y from both sides

2x + 2y (-2y) = 10 (-2y)

2x = 10 - 2y

Isolate the x, divide 2 from both sides and from all terms.

(2x)/2 = (10 - 2y)/2

x = 5 - y

Place the variable in the front

x = -y + 5

x = -y + 5 is your answer

Answer:

$\huge\boxed{\sf 6.25 \ g}$

Step-by-step explanation:

After every Half life , Half of the mass is left.

After 1st Half life = 100 g / 2 = 50 g

After 2nd Half life = 50 / 2 = 25 g

After 3rd Half life = 25 / 2 = 12.5 g

After 4th Half life = 12.5 / 2 = 6.25 g

$\rule[225]{225}{2}$
