Combine like terms. Like terms are terms that are the same excluding coefficients.

-b+2b=b
-5x-4x=-9x
-3+7=4

Put it all together
Final answer: b-9x+4

oee [108]

Answer:

1.5 units squared

Step-by-step explanation:

Area of a Triangle formula: A = 1/2bh

Pythagorean Theorem: a² + b² = c²

Since you are missing the <em>h </em>to find the area of the triangle, you must use Pythagorean to find the 3rd missing side (it is a right triangle so you can use Pythagorean).

Step 1: Use Pythagorean

2.5² = 1.5² + b²

4 = b²

b = 2

Step 2: Switch variables

b (from Pythagorean) = h (height for Area)

Step 3: Solve for Area

A = 1/2(1.5)(2)

A = 1.5

And you have your final answer.

X÷0.4=2 1/9 ÷3 1/6 please find x!!
lakkis [162]

Answer:

0.3

Step-by-step explanation:

x÷0.4=2 1/9 ÷3 1/6

x÷0.4 = 19/9/19/6

x/0.4 = 19/9 ×6/19

x/0.4 = 114/171

cross multiply

171x = 114×04

171x = 45.6

divide by 171

171x/171 = 45.6/171

x=0.266

x=0.3 approximately
