Find a rational number halfway in between the two numbers. three sevenths and one tenth

strojnjashka [21]

Answer:
The rational number is : 37/140

Explanation:
The first number given is three sevenths which can be written as 3/7
The second number given is one tenth which can be written as 1/10

Now, we want to get the midpoint between these two numbers. The midpoint can be calculated as follows:
midpoint = (first number + second number) / 2
midpoint = [(3/7) + (1/10)] / 2
midpoint = 37/140

Hope this helps :)

The sum of two numbers is 0. Twice the smaller number subtracted from 3 times the larger number is 10. Let x represent the large

Bezzdna [24]

Answer:

x+y=0 and 3x-2y=10

Step-by-step explanation

Let the numbers be x and y.

The sum of the two numbers is 0

$\implies \: x + y =0$

Letting the smaller number be y and the

larger number be x:

twice the smaller number

$\implies \: 2y$

Also, 3 times the larger number

$\implies \: 3x$

Now ,twice the smaller number subtracted from 3 times the larger number is 10.

$\implies \: 3x - 2y = 10$

Therefore the equations are

$x + y =0$

and

$3x - 2y =10$

Please help me with this question :)

klio [65]

Answer:

y>5/6

Step-by-step explanation:

5y+3>-7y+13

5y+7y>13-3

12y/12>10/12

y>5/6

This is an inequality, which shows where the variable y does or does not exist

from this we can say

y: (-infinity,5/6) (5/6, infinity]

or, y does not exist from (-infinity,5/6)

and does exist from (5/6, infinity]

What are the coordinates of the midpoint of ab?

mars1129 [50]

Your answer will be A because you have to get the sum of 4 and 8 and then divide by 2. Which is 6 for the x coordinate. The you need to take the sum of -5 and -1 and then divide by 2. Which is -3 for the y coordinate. So the answer is (6,-3).
