arianne is taking a geometry course and is working with the area of triangles. she knows the area and the height but needs to find the base. rearrange the following equation for b, where a is the area, b is the base, and h is the height of the triangle.
a = 1/2bh
b = 2a − h
b = 2a/h
b = 2a + h
b = 2ah

Step-by-step explanation:

∵ Area of a triangle,

Where,

b = base of the triangle,

h = height of the triangle,

For finding the formula for b we need to isolate b in equation (1),

For this divide both sides by

We get,

Hence, SECOND option is correct.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
