Kira John and Ryan sent a total of 112 text messages during the weekend. Kira sent 8 fewer messages than Ryan. John sent 4 times

Softa [21]

Answer:

Kirasent 16 and Ryan sent 96

Step-by-step explanation:

I got this because Kira is x-8 and Ryan is 4x. 4x-x-8=112 is equal to 5x=120. So x=24.Kira has 16 when plugging in x and Ryan has 96 because 4 times 24 is 96.

Find the area of the triangle below. Show as much work as possible. Label your answer appropriately.

Dmitry [639]

Answer:

$Area=\frac{5}{12}x^2$

Step-by-step explanation:

The area of a triangle is given by:

$Area=\frac{1}{2}*base*height$

From the diagram $base=\frac{5}{6}x,and,height=x$

We substitute into the formula to get:

$Area=\frac{1}{2}*\frac{5}{6}x*x$

This implies that:

$Area=\frac{5}{12}x^2$
