Select the correct answer from each drop-down menu. Two of the solutions for the equation 2x + 3y = 12 are (9, ) and (, 4).

frutty [35]

Answer:

Step-by-step explanation:

$2x+3y=12\\\\(9,\ y)\to\text{put x = 9 to the equation of a line:}\\\\2(9)+3y=12\\18+3y=12\qquad\text{subtract 18 from both sides}\\3y=-6\qquad\text{divide both sides by 3}\\y=-2\\\boxed{(9,\ -2)}\\\\(x,\ 4)\to\text{put y = 4 to the equation of a line:}\\\\2x+3(4)=12\\2x+12=12\qquad\text{subtract 12 from both sides}\\2x=0\qquad\text{divide both sides by 2}\\x=0\\\boxed{(0,\ 4)}$

What is the sum of –356.1 + 258.6

xxTIMURxx [149]

Answer:

Step-by-step explanation:

-356.1 + 258.6 = -97.5

Imagine a long timeline with 0 in the middle, on the left we have -356.1 and on the right we have 356.1. Adding numbers makes the timeline move right.

Starting from the left, add (+) 258.6 to the number (moving right along the timeline). As 356 is larger than 258, the scale does not reach 0 yet and therefore the number must be negative.

Using this logic, the answer is 97.5
