C -2 because of the thanos
Answer:
10
Step-by-step explanation:
Use order of Operations - PEMDAS
First, (2x3) = 6
Now you have, 1+6-(-3)
Then take the -(-3) and make it +3, cause a subtraction and negative sign make a positive.
Now you have, 1+6+3
Then add it all together to get 10
Answer: See explanation
Step-by-step explanation:
Michael is X years old.
Jenny is twice as old as Michael. Thus means that Jenny = 2 × x = 2x
The sum of their ages is 57.
Therefore, x + 2x = 57
3x = 57
x = 57/3 = 19
Michael is 19 years
Jenny's age = 2x = 2 × 19 = 38 years
Answer:
The length is 25 units and the width is 11 units
Step-by-step explanation:
Let the length of the rectangle be l.
Let the width of the rectangle be w.
We are given that the length of the rectangle is three times more than twice its width. This means that:
l = 3 + 2w
The perimeter of a triangle is given as:
P = 2(l + w)
This implies that:
P = 2[(3 + 2w) + w]
P = 2(3 + 3w)
We can use this to find the width of the rectangle and then the length.
The perimeter of the rectangle is 72 units.
Therefore:
72 = 2(3 + 3w)
72 = 6 + 6w
=> 6w = 72 - 6 = 66
w = 66 / 6 = 11 units
The length, l, is therefore:
l = 3 + 2(11) = 3 + 22 = 25 units
Mrs Darnell will need to walk about 5,907 steps.
Carlos should get about $4.32 in change.
Hope this helps! ;)
