What is missing for the following quantity to be true? (2y + 4b) + 5 = ___ + (4b + 5)

1 answer:

7 0

1)Write the equation again, but replace ___ with x:
(2y + 4b) + 5 = x + (4b + 5)
2) Eliminate parenthesizes (if there is "-" in front of them, change the sign in front of everything that is inside them; if there is "+" just leave it the same):
2y + 4b + 5 = x + 4b + 5
3) Transfer 4b + 5 from the left side to the right by changing signs into the opposite ones:
2y = x + 4b + 5 - 4b - 5
2y = x
So, the answer will be 2y. Hope this helps!

Need help ASAP. i forgot all the steps after the Area is solved with 5. or if 25pi is the right answer.

Answer:

$42.5\:\mathrm{m^2}$

Step-by-step explanation:

The area of a sector with measure $\theta$ in degrees is given by $r^2\pi\cdot\frac{\theta}{360}$ , where $r$ is the radius of the sector.

What we're given:

$r$ of 5
$\theta$ of $195^{\circ}$

Solving, we get:

$A_{sector}=5^2\pi\cdot \frac{195}{360}=13.5416666667\pi=42.5424005174\approx \boxed{42.5\:\mathrm{m^2}}$

*Notes:

units should be in square meters (area)
the problem does not say whether to round or leave answers in term of pi, so you may need to adjust the answer depending on what your teacher specifically wants

Approximate √700 to the nearest tenth.

castortr0y [4]

The square root of 700 (√700) is 26.4575131106

The tenths place is the first number after the decimal. In this case the number in the tenths place is...

26.4575131106

To determine if you round up or stay the same you must look at the number after the 4 in the tenths place. In this case the number after the 4 decimal is 5.

A number will round up if this number (5) is 5 or greater. If it is smaller then 5 then the decimal will not round up.

In this case this means that the 4 will round up...

26.5

Hope this helped!
