<span>Just in case you didn't understand them :)

So we start off by breaking it down!!
3:4, 3+4=7 

In other words (or any at that lol) we find out that 280 can be broken off into 3 parts!

3 part=3/7×280  = 120
giving us 120 as the end result! 

</span><span>We also find out that 280 can be broken off into 4 parts!
</span><span>
4 part =4/7×280=160
Leaving us with 160

Meaning that now, we put the two new found ratios together to create our answer!! :)

So, 3:4 now equals 120:160

So your answer will be 120:160

</span> I hope this helps, I know that it helps for me when someone breaks it down for me! :)

A new car costs $8000 at full price. With a sales tax of 5.75%, how much will the car cost in total?​
ioda

Answer:

$8460

Step-by-step explanation:

So for this problem we will use the base price of $8000 and add the additional cost of the 5.75% to find the total cost for the car.

So, to find the 5.75%, we simply multiply 8000 by .0575 to get 460.

So 8000 + 460 = 8460.

Thus, the total price of the car would be $8460.

Cheers.

the sum of three numbers is 79. The second number is 5 times the first, while the third is 16 more than the first. Find the numb
swat32
Let the 1st number be x; 2nd number be y; 3rd number be z.

x + y + z = 79

x = number we are looking for.
y = x * 5 ==> 5 times the first
z = x + 16 ==> 16 more than the first

Therefor,

x + (x * 5) + (x+16) = 79

1st step, multiply the 2nd number: x * 5 = 5x

x + 5x + x + 16 = 79

Add all like numbers:

7x + 16 = 79

To get x, transfer 16 to the other side and change its sign from positive to negative.

7x = 79 - 16
7x = 63

To get x, divide both sides by 7

7x/7 = 63/7
x = 9

To check. Substitute x by 9.

x + (x * 5) + (x+16) = 79

9 + (9 * 5) + (9 + 16) = 79
9 + 45 + 25 = 79
79 = 79 equal. value of x is correct.
