Answer: No solution
Step-by-step explanation:
9-(-8)=20 given
9+8=20 the two negatives cancel out, making the eight positive
17=20 this statement is not correct, so the answer is no solution
no solution
I'm not sure if there was supposed to be a variable in there somewhere, but I did my best to explain. Hope this helps!
Answer: B) 16 units
Step-by-Step Explanation:
As we can observe from the graph,
Length (l) = 5 units
Breadth (b) = 3 units
Perimeter = 2(l + b)
Therefore,
= 2(l + b)
= 2(5 + 3)
= 2(8)
= 2 * 8
=> 16
Perimeter = 16 units
Answer:
17, 19 and 21
Step-by-step explanation:
Consecutive odd numbers mean odd numbers that are right next to each other.
Eg: 3, 5, 7
Let x represent the youngest sister. The sister older than her will be 2 years older than her, hence (2 + x). The oldest sister would be 4 years older than the youngest and two years older than the middle sister, hence (4 + x).
The sum of their age = 57.
Hence:
x + (2 + x) + (4 + x) = 57
x + 2 + x + 4 + x = 57
Simplify
3x + 6 = 57
Rearrange
3x = 57 - 6
3x = 51
Divide both sides by 3 to make x on its own (this way we can find the age of the youngest sister).
x = 17 (youngest sister is 17 years old)
x + 2 = 19 (middle sister is 19 years old)
x + 4 = 21 (oldest sister is 21 years old)
Answer:
x = 3, y = 3
Step-by-step explanation:
x = -5x -18
5x + 18 = -x
6x + 18 = 0
6x = 18
x = 3
