What is the answer to -4/3p -2/5

Mathematics
1 answer:
kaheart [24]3 years ago
5 0

Answer:

Step-by-step explanation:

This expression consists of two fractions that have no common denominator but do have -2 as a common factor in the numerators.

Factoring out the -2, we get:

-2(2p/3 + 1/5)

If you want to go further, we can determine the LCD (which is 15) and then combine the fractions within parentheses:

-2(10p/15 + 3/15)

We could now factor out the 1/15 in each fraction:

-2

---- (10p + 3)

15

<h2>Answer: 8</h2>

Step-by-step explanation:

10x+45 > 120\\10x+45-45 > 120-45\\10x > 75\\\frac{10x}{10} > \frac{75}{10} \\x > 7.5

Therefore, Mel has to work at least 7.5 hours or 8 total hours.

I NEED HELP ASAP PLEASE AND THANKS.
yanalaym [24]

Answer:

b=320; slope=-30

Step-by-step explanation:

if you look along the y-axis find the spot that the line intercepts and then that's b

now for the slope

find two points on the line, i chose(8 , 120) and (4 , 240)  

use the slope formula: y2-y1 over x2-x1

240-120=120 and 4-8= -4

so the slope is 120/-4 and that can be simplified to 30/-1 or -30

Find four consecutive integers such that 8 times the sum of the first and the third is 40 greater than 10 times the fourth
tatuchka [14]

All four consecutive integers will be 9, 10, 11, and 12 and can be found out by high common sense.

<h3>What is the pattern?</h3>

A pattern is a specific arrangement of numbers or any term which will follow a specific code or hint.

For example 2,4,6,8 in this, the difference between any two-term is only 2 and this will be its specific pattern.

Given that,

8 times the sum of the first and the third  =  8( 1st + 3rd)

40 greater than 10 times the fourth = 40 + 10(4th)

So,

8( 1st + 3rd) = 40 + 10(4th)

Now if we look right and side then it will come out as any number with the unit placed as 0.

So it means on the left side also the unit place must be 0.

By thinking of  1st + 3rd = 10 /20 because at 45 it will be 40 which is not equal to the right-hand side.

Now by hit and trial method, we need to guess it 20 = 9 + 11

Then

8(9 + 11) = 40 + 10(12)

One equation can never give us three unknowns hence it will be the correct way.

Hence so the four consecutive integers will be 9, 10, 11, and 12.
