$b = - 7 \: y = 7$

$b - 4y$

$( - 7) - 4(7)$

$- 7 - 28$

$= - 35$

30 tens times 5 hundreds= 50 tens and 3 hundreds true or false?

Pavlova-9 [17]

Answer:

true

Step-by-step explanation:

Somebody once told me the world is gonna roll me

I ain't the sharpest tool in the shed

She was looking kind of dum with her finger and her thumb

In the shape of an "L" on her forehead

Well the years start coming and they don't stop coming

Fed to the rules and I hit the ground running

Didn't make sense not to live for fun

Your brain gets smart but your head gets dum

So much to do, so much to see

So what's wrong with taking the back streets?

You'll never know if you don't go

You'll never shine if you don't glow

Hey now, you're an all-star, get your game on, go play

Hey now, you're a rock star, get the show on, get paid

And all that glitters is gold

Only shooting stars break the mold

It's a cool place and they say it gets colder

You're bundled up now, wait 'til you get older

But the meteor men beg to differ

Judging by the hole in the satellite picture

The ice we skate is getting pretty thin

The water's getting warm so you might as well swim

My world's on fire, how about yours?

That's the way I like it and I'll never get bored

Hey now, you're an all-star, get your game on, go play

Hey now, you're a rock star, get the show on, get paid

All that glitters is gold

Only shooting stars break the mold

Hey now, you're an all-star, get your game on, go play

Hey now, you're a rock star, get the show, on get paid

And all that glitters is gold

Only shooting stars

Somebody once asked could I spare some change for gas?

I need to get myself away from this place

I said, "Yup" what a concept

I could use a little fuel myself

And we could all use a little change

Well, the years start coming and they don't stop coming

Fed to the rules and I hit the ground running

Didn't make sense not to live for fun

Your brain gets smart but your head gets dum

So much to do, so much to see

So what's wrong with taking the back streets?

You'll never know if you don't go (go!)

You'll never shine if you don't glow

Hey now, you're an all-star, get your game on, go play

Hey now, you're a rock star, get the show on, get paid

And all that glitters is gold

Only shooting stars break the mold

And all that glitters is gold

Only shooting stars break the mold

Graph thee line that represents this equation:<br>y+2=1/2(x+2)

Yuliya22 [10]

Answer:

$y = \frac{1}{2} x - 1$

Explanation:

The first pic shows the line graphed, while the second pic shows how to turn the equation into proper slope-intercept form.

The only steps the second pic is missing however, is flipping the sides around to be better understood (optional), and more importantly subtracting 2 on both sides in order to move it to the other side, to get 2y = x - 2. And dividing the 2 on both sides to get y by its self, to get:

y = (x-2)/2 , or y = 1/2 x - 2/2 , which if you notice 2/2 makes it equal to one whole so your answer is y = 1/2 x - 1 .

If you like this answer can you please mark me brainliest? :)

A deck of ordinary cards is shuffled and 13 cards are dealt. What is the probability that the last card dealt is an ace?

alexandr1967 [171]

Answer:

The probability that the last card dealt is an ace is $\frac{1}{13}$ .

Step-by-step explanation:

Given : A deck of ordinary cards is shuffled and 13 cards are dealt.

To find : What is the probability that the last card dealt is an ace?

Solution :

There are total 52 cards.

The total arrangement of cards is 52!.

There is 4 ace cards in total.

Arrangement for containing ace as the 13th card is $4\times 51!$ .

The probability that the last card dealt is an ace is

$P=\frac{4\times 51!}{52!}$

$P=\frac{4\times 51!}{52\times 51!}$

$P=\frac{4}{52}$

$P=\frac{1}{13}$

Therefore, the probability that the last card dealt is an ace is $\frac{1}{13}$ .

What is the missing base 256 = ^4

Inessa05 [86]

So the problem is $256=x^4$ and you need to find x.

You can find x by taking fourth root of 256. The easiest way is to use your calculator. On my scientific calculator, it is 2nd then the button ^ that is $\sqrt[x]{}$
You get the answer of 4.
