Answer:
1. The larger number is 2x + 7. The smaller number is x.
Let x be the smaller number
(7 + 2x) + x = 43
Since they are all in addition, we can get rid of the parenthesis.
7 + 2x + x = 43
2x and x are similar variables, we can add them both together.
7 + 3x = 43
7 + (-7) + 3x = 43 + (-7)
3x = 36
3x/3 = 36/3
x = 12
Let's check
[7 + 2(12)] + 12
(7 + 24) + 12
31 + 12 = 43
42 / 7 = 6
bc it is the complete opposite
Answer:
1) (-50) <(-25) < (-10) < 10 < 25
2) 150 in^2
Step-by-step explanation:
For the first question we list the numbers according to their sign(start from negative)
For the second question we multiply height with width to find the area of the rectangle.
Answer:
-60 and -28
Step-by-step explanation:
