The formula for the area of a trapezoid is A=1/2h (b1+b2) express b1 in terms of A, h, and b2

Answers

Answer 1

Answer: A=1/2h(b₁+b₂)
1/2h(b₁+b₂)=A
(b₁+b₂)=2A/h
b₁=2A/h - b₂

answer: b₁=2A/h - b₂

What needs to be done before you try to solve the equation 2x2 = -6+ 8a?

Answers

Answer: You need to separate the variable (A) from the rest of the equation.

Step-by-step explanation:

Simplify and move everything except the variable
2x2 = -6 + 8a >>> 4 = -6 + 8a >>> 10 = 8a
Then, divide both sides by the amount of A (8)
10 / 8 = 1.25
8 / 8 = 1
1.25 = A

PROVE ALGEBRAICALLY THAT 0.5 = 5/9

Answers

Answer:

See Below.

Step-by-step explanation:

Let:

$0.\overline{5}=n$

If we multiply both sides by 10, we get:

$5.\overline{5}=10n$

Now, we will subtract n from both sides:

$5.\overline{5}-n=10n-n$

On the left, we can replace the n:

$5.\overline{5}-.\overline{5}=10n-n$

Subtract:

$5=9n$

Divide both sides by 9:

$n=(5)/(9)$

Hence:

$n=0.\overline{5}=(5)/(9)$

Final answer:

Algebraically, 0.5 does not equal to 5/9. Instead, when 5/9 is converted to a decimal it equals approximately 0.56. The correct fraction representation of 0.5 is 1/2.

Explanation:

I'm sorry, but there seems to be a misunderstanding in your question. The algebraic representation of 0.5 is not equal to 5/9. If you convert 5/9 to a decimal, using division on a calculator or by hand, it doesn't equate to 0.5, but rather approximately 0.56. Let's go through the conversion step by step:

1. Divide the numerator (5) by the denominator (9).

2. This will give you a decimal approximation for the fraction.

So, 5 ÷ 9 = 0.56 (rounded to two decimal places).

This clearly shows that algebraically 0.5 does not equal 5/9. The valid algebraic equivalent of 0.5 in terms of fraction is 1/2.
