n your notebook, set up the following subtraction in a vertical format and select the correct answer. Reduce 7y + 2y 2 - 7 by 3

exis [7]

Answer:

$\frac{2y^2+7y-7}{3-4y}$

Step-by-step explanation:

We are given

$\frac{7y+2y^2-7}{3-4y}$

we can rewrite it as

$\frac{2y^2+7y-7}{3-4y}$

we know that

2y^2+7y-7 can not be factored

so, we can not reduce this expression

because this is the only way to reduce it

so, we get reduced form as

$\frac{2y^2+7y-7}{3-4y}$

A snail is moving along a path that is 4 meters long. The snail moves at an average rate of 3 3/10 inches per minute. Question 1

Troyanec [42]

Answer: The length of the path = 157 inches { approx}

Step-by-step explanation:

Given: The length of the path = 4 meters

1 meter = 100 centimeters

So 4 meters = 400 centimeters

Also 1 in. ≈ 2.54 cm

$\Rightarrow\ 1 cm = \dfrac{1}{2.54}\ in.$

Now, $\text{ 400 centimeters}=400\times\dfrac{1}{2.54}\text{ inches}$

$=157.480314961\approx 157 \ \ \ \ \ \text{ [Rounded to the nearest inch.]}$

Hence, the length of the path = 157 inches { approx}
