Place is highest to lowest 3/4 84% 1/3 0.82

sesenic [268]

ANSWER

84%,0.82,¾,⅓

EXPLANATION

Convert everything to decimals.

$\frac{3}{4} = 0.75$

$84\% = 0.84$

$\frac{1}{3} = 0.333....$

The last one is already in decimals.

$0.82$

We can now see clearly, that

$0.84 \: > \: 0.82 \: > \: 0.75 \: > \: 0.3333...$

This implies that,

$84\% \: > \: 0.82 \: > \: \frac{3}{4} \: > \: \frac{1}{3}$

Hence from highest to least, we have

84%,0.82,¾,⅓

Solve for w 7=-4w+7 w=

devlian [24]

Answer:

Step-by-step explanation:

If I'm not mistaken, the answer must be 0.

7-7 is 0, that cancels out

0 divided by -4w is zero. That leaves w alone

w=0. I think that's the answer.

-7p (p+8)=21 is equal to

andrew11 [14]

We have the equation:

$-7p(p+8)=21$

So then we need to distribute -7p to the parentheses:

$-7p^{2}+(-56p)=21$

Then we need to set the equation equal to 0, so we must subtract 21 on both sides:

$-7p^{2}-56p-21=0$

Then we need to factor this. So we end up with:

$7(-x^{2}-8p-3)=0$

This is as much as this can be factored, so we cannot go any further.
