Which expression would be equivalent to: Which expression would be equivalent to: \frac{1+b}{2} - 3(a-1)

IrinaVladis [17]

Answer:

$\frac{1+b}{2} - 3(a-1) = \frac{b- 6a+7}{2}$

Step-by-step explanation:

Given

$\frac{1+b}{2} - 3(a-1)$

Required

An equivalent expression

$\frac{1+b}{2} - 3(a-1)$

Take LCM

$\frac{1+b}{2} - 3(a-1) = \frac{1+b- 2*3(a-1)}{2}$

$\frac{1+b}{2} - 3(a-1) = \frac{1+b- 6(a-1)}{2}$

Open bracket

$\frac{1+b}{2} - 3(a-1) = \frac{1+b- 6a+6}{2}$

Collect like terms

$\frac{1+b}{2} - 3(a-1) = \frac{b- 6a+6+1}{2}$

$\frac{1+b}{2} - 3(a-1) = \frac{b- 6a+7}{2}$

Hence, an equivalent expression is:

$\frac{b- 6a+7}{2}$

So far, Kim has learned 89% of her spelling word. Her sister Avery has learned 82 out of her 98 spelling word. Who has learned a

Tema [17]

So for Avery, we would need to divide 82/98, which will get you (rounded to the thousandths) 0.837. To get from decimal form to percentage form, just move the decimal point 2 spaces to the right. In this case, the percentage is 83.7%

Since Kim has learned 89% of her spelling words while Avery has learned 83.7% of her spelling words, Kim has learned a greater percentage of spelling words than Avery.
