Urgent!!! PLEASE HELP, FAST!!!All the items on the sale rack were 75 percent off their original price.
(empty table is shown)
If Jill bought an item on the sale rack and saved a total of $84, what is the value of x in the table above? (x=1/4)

84 = 3/4
how much is 1/4?
possible answers:
$21
$28
$84 - not
$112 - not

Answers

Answer 1

Answer: The best way to solve this is to put it into a proportion:
$(x)/(84) = ( (1)/(4) )/( (3)/(4) )$
So you cross multiply to get:
$21= (3)/(4) x$ (the 21 is from $(1)/(4)$ •84)
Then multiply by $(4)/(3)$
And you get $28, so the reduced price would be $28.

9a-5a for a=7 what is the answer

Answers

Hi there!

To solve your answer, since we know a = 7, we can easily solve your equation.

But before we go onto that, I want to show you a tip or two about solving equations with variables next to numbers.

When you have a number, and a variable attached to it, it means to multiply.

Now, to make this equation look a little easier, lets rewrite it.

9 × 7 - 5 × 7 = ___

According to PEMDAS, we won't go straight from left-to-right when solving here. We'll skip around a little.

9 × 7 = 63.

5 × 7 = 35.

Now, since we've multiplied the two numbers, its time to subtract them.

63 - 35 = 28. Sooooo........

9 × 7 - 5 × 7 = 28

Hope this helps!

Message me if you need anything else, I'd be happy to help you out! :D

the answer is 28
when a number is attached by a variable, that usually means that it is attached by multiplication so, i multiplied 9 times 7 and got 63 then i multiplied 5 times 7 and got 35 then subtract 63 and 35 and i got 28
i hope this helps :)

What is the slope of a line passing through (3, 4) and (5,8)?
1/2
2
2/4
4/2

Answers

Answer:

Step-by-step explanation:

To find the slope of a line given two points $(x_1,y_1) \text{ and } (x_2,y_2)$ you could use the formula: $(y_2-y_1)/(x_2-x_1) \text{ or even } (y_1-y_2)/(x_1-x_2)$ .

However, what I'm fixing to do is equivalent to that except I think easier to remember.

You line up the points vertically and subtract, then put 2nd difference over 1st difference.

Like this:

( 3 , 4)

- ( 5 , 8)

---------------

-2 -4

So the slope is -4/-2=4/2=2.

The slope is 2.

How do you regroup 607 -568

Answers

Answer:

By changing group of ones into tens

Step-by-step explanation:

Regrouping refers to changing group of ones into tens to make subtraction easy.

Here, we need to regroup 607 -568 .

In subtraction, we start subtracting digits from ones place.

In number 607, digit at ones place is 7 and in 568, digit at ones place is 8.We can't subtract 8 from 7, so, we will try to borrow 1 from the digit at tens place in 607, but digit at tens place in 607 is 0, so it's possible to take 1 from 0.

So, first we will take 1 from 6 ( digit at hundreds place in 607 is 6 such that 6 becomes 5 ) to 0 at tens place which will become 10 then take 1 from 10 to 7 which will then become 17.

Then , we will subtract 8 from 17.

From the figure:

Cross out the 6, make it a 5 and shift 1 which we have subtracted from 6 to 0 such that 0 becomes 10 then cross the 10, make it a 9 and shift 1 which we have subtracted from 10 to 7 such that 7 becomes seventeen .

Cross out the 6 make it a 5 then make the 0 a 10 then cross the 10 out make it a 9 and the 8 an eighteen then subtract it all
