Answer: <em>4a - 5 = 10 - a <=> 4a + a = 10 + 5 ( chuyển vế đổi dấu, số 1 vế biến 1 vế) <=> 5a = 15 ( a đi 1 mình nghĩa là 1a) </em>

Answer: <em>4a - 5 = 10 - a <=> 4a + a = 10 + 5 ( chuyển vế đổi dấu, số 1 vế biến 1 vế) <=> 5a = 15 ( a đi 1 mình nghĩa là 1a) <=> a = 3 ( lấy 15 : 3 = 5 )</em>

Find the slope of the line 7x-4y=10
Harman [31]

Answer:

The slope is m=(7/4)

Step-by-step explanation:

we know that

The equation of the line into slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-coordinate of the y-intercept

In this problem we have

7x-4y=10

so

Convert to slope intercept form

Isolate the variable y

4y=7x-10

y=(7/4)x-(10/4)

y=(7/4)x-(5/2)

The slope is m=(7/4)

The LCM of two numbers is 48. The number one in the ratio 2:3. Then Sum of the numbers is:
Oksi-84 [34.3K]

Answer:

40

Step-by-step explanation:

Let the numbers be 2x and 3x

Then their L.C.M. = 6x

BUT also their LCM=48

6x=48

x=48/6

x=8

So,

First number=2x=2x8=16

Second number=3x=3x8=24

The numbers are 16 and 24.

Hence required sum =(16+24)=40

So none of the options are correct
