Answer:

x=6

Step-by-step explanation:

We can use ratios to determine the value of x

x 9

------ = ----------

10 15

Using cross products

15x = 9*10

15x = 90

Divide each side by 15

15x/15 =90/15

x = 6

6x-2y=24 how do u solve for y

Tatiana [17]

It's Diophantine equation.
First, we need to found gcd(6,(-2)):
6=2*3
(-2)=(-1)*2

So, gcd(6,-2)=2
Now, the question is. Can we dived c=24, by gcd(6,-2) and in the end get integer?
Yes we can.
$\frac{24}{2} =12$
So, we can solve it.

Now is the formula:
${\begin{cases}x=x_{0}+n{\frac {b}{\gcd(a,\;b)}}\\y=y_{0}-n{\frac {a}{\gcd(a,\;b)}}\end{cases}}\quad n\in \mathbb {Z} .$

Second, we need the first pair (x0,y0)
if
x=0
then
$y=(-12)$

Third, we gonna use that formula:
${\begin{cases}x=-n}\\y=-3(4+n)}\end{case}\quad n\in \mathbb {Z} .$
Congratulations! We solve it.

5. If necessary, the hundredths. .04 + 1.8 = round to

s2008m [1.1K]

Answer:1.84

Step-by-step explanation: We can add this in a very easy way.

Step 1- We can put the 1 in the ones place as if there is no number before a decimal (which is the case for the first number) we can assume it is 0.

Step 2- We can then place the decimal point after the 1 and then put 0.8 since there are no more numbers that are at the tenths

Step 3- At the end we add the .04 (also known as 0.04) as there are no more places in both the numbers that are in the hundredths (and in 1.8, it can also be known as 1.80 as there are none!)

Hope this helps!

I would appreciate if you can mark me brainliest :)
