Solve the inequality: 3/10 is greater than or equal to k - 3/5

Mathematics
1 answer:
Ostrovityanka [42]3 years ago
3 0

To solve the inequality 3/10 is greater than or equal to k - 3/5, we must first set it up. Since 3/10 is greater than or equal to something, we will have a greater than or equal to symbol, with the 'mouth' pointing towards 3/10. Setting this up we get:

3/10 ≥ k - 3/5

Now we want to get k by itself on one side. We can do this by adding 3/5 to each side.

3/10 + 3/5 ≥ k

Simplify

9/10 ≥ k

A new bank account is opened on week 1 with a $200 deposit. After that first week, weekly deposits of $55 are made in the accoun
kobusy [5.1K]
On week 1, we started with a deposit of $200. Every week from that point on, we place a deposit of $55.

We know y is total amount of money (deposits) in the bank account.
We also know x represents the number of weeks.

On week 1, we would have $200 in the back account.
On week 2, we would have $200 + $55 or $255 in the bank account.

So, we could build an expression of 55(x - 1) + 200 which is equal to y.

So, y = 55(x - 1) + 200 is the answer.

When you roast coffee, it loses 12% of its weight. how much fresh coffee do you need in order to get 14 2/25 lb of roasted coffe
Komok [63]

Answer:

16 lb of fresh coffee.

Step-by-step explanation:

Let  x pound be the  amount of fresh coffee needed.

100 - 12 = 88%  is equivalent to 14 2/25  of roasted coffee.

By proportion  x = 14 2/25  /  88/100

= 352 / 25 * 100/88

= 35200 / 25 * 88

= 16 lb  (answer).

Mario painted 2/6 of the wall in his bedroom. Mei Lyn painted 2/4 of a wall in her bedroom.
Lesechka [4]
Well I am assuming you want to compare them or something so yeah:

You have to find a common denominator of 4 & 6, so you could multiply them together, this makes 24. Because you have to do the same thing to the top and the bottom, you have to multiply 2/4 (which is now 2/24) by 6, and the 2/6 (which again is 2/24) by 4 which leaves you with 12/24 (2/4) and 8/24 (2/6).

We can simplify these fractions by dividing them, but as you may know 12 is half of 24 so 12/24 would also be 1/2.
If you keep dividing by 2 you will find that 8/24 is also equal to 1/3. This is easier to find out by the beginning number but I mentioned it anyway because I didn't understand what you were asking.

Overall if you noticed when comparing 2/4 and 2/6 we found that Mei Lyn painted more wall than Mario.
