Add 509 and 12:
509
+ 12
____
521
509 + 12 = 521
I think the answer to the property of complex numbers is demonstrated below is Commutative Property of Addition. Option number 4 is correct.
Answer: 54 is 112.5% of 48.
Answer:
121 x 59 (Dimensions)
Step-by-step explanation:
6x + 6 = 360
Take away 6 from both sides
6x = 354
Divide both sides by 6
x = 59
The length is 2x + 3 because it says 3 more than double the width (lenght is x). You have 2 widths and 2 lengths. The two widths are both x (2x). The two lengths are both 2x + 3 (4x + 6). 2x + 4x + 6 = 6x + 6.
Now input 59 for x
2(59) + 3 = 121
x = 59
Check Your Answer
121 is just one length and 59 is just one width, so you have to multiply both sides by 2 because you have 2 widths and 2 lengths.
121 x 2 = 242
59 x 2 = 118
242 + 118 = 360
Answer:
10
Step-by-step explanation:
-3 = 7 - x
Add x to both sides
x -3 = 7 - x +x
x - 3 = 7
Now, add 3 to both sides
x - 3 + 3 = 7 + 3
x = 10
