Answer:

The system of equations 8x-3y=10 and 16x-6y=22 has no solution

Step-by-step explanation:

When both of the above equations are put into standard form, you get ...

8x - 3y = 10

8x - 3y = 11

This is an "inconsistent" pair of equations. There are no values of x and y that can satisfy both equations, hence there is no solution.

The sum of two consecutive numbers is -165. Find the value of the smaller number.
zalisa [80]

Let's say the smaller number is x.  Then, we can represent the larger number as x + 1. The +1 means that it's both larger, because adding makes a number larger, and consecutive, because it's 1 greater or less.

Then, we can write an equation. The sum of the two numbers is x + (x + 1), and it's equal to -165.

x + (x + 1) = -165

2x + 1 = -165

2x = -166

x = -83

Since x = -83, the smaller number is -83.

Tom [10]

Answer:

r = -46/3

Step-by-step explanation:

-3(r+2)=40

Distribute

-3r - 6 = 40

Add 6 to each side

-3r-6+6 = 40+6

-3r = 46

Divide by -3

r = 46/-3

r = -46/3
