Mathematics
1 answer:
Leviafan [203]3 years ago
7 0

Answer:

[-11/5,∞)

Step-by-step explanation:

1. Add 4 to both sides: 7x-4+4≥-15+2x+4

2. Simplify: 7x≥2x-11

3. Subtract 2x from both sides: 7x-2x≥2x-11-2x

4. Simplify: 5x≥-11

5. Divide both sides by 5: 5x/5≥-11/5

6. Simplify: -11/5

What is less than 5/6 with a denominator of 8
azamat
Chose a fraction with a denometer of 8.
Ex: 3/8

To compare 5/6 and 3/8 we need to find the LCM (the lowest common denominator.)

This can easily be done by listing the multiples of each number.
6: 6, 12, 18, 24, 30, 36
8: 8, 16, 24, 32, 40, 48

The Lowest common denominator would be 24.

6*4=40
8*3=40

Since we altered the denometer, either by multyplying by 6 or 8 (to get 24), we must do the same for the numerator.

3/8*3
9/24

5/6*4
20/24

Now we compare the fraction properly.
20 is larger than 9 so we know that 3/8 is less than 5/6.

Hope this helps! Please leave a thanks/braniest answer!

myrzilka [38]

Answer:

21 pieces

Explanation:

The 3in one could be written as 24/8, because it equals 3.

So you find how many 3/8s are inside 24/8, the answer would be 8 pieces for the first one.

Then the 5in one is=40/8

With this one you would have 13 pieces and 1/8 lasting.

someone help on the "how did basil know" part before i sue and quit school. i just wanna sleep it's 12 am.
PtichkaEL [24]
Well, the last digit in the product will only come from the last digits of the numbers that you're multiplying together. So for 0.303 & 4.48, that last digits are 3 & 8 so that last digit in the product would come from
3 \times 8 = 24
So 4. There are only two options that end in 4, 1.35744 & 0.13574. You can by the magnitude of the numbers that it isn't as small as 0.13574 so the answer must be 1.35744.
