Answer:
50%
Step-by-step explanation:
if there are 2 sets of 7 marbles each part is worth 50% (them put together is 100%). Therefore you have a 50% chance of getting a red marble
Answer:
y=2x+4
Step-by-step explanation:
Answer:
2x - 0.4x ;
8x/5 ;
Yes
Step-by-step explanation:
Let number of miles = x
Arlene:
Double number of miles = 2 * x = 2x
Subtract 20% of the result :
2x - 20% of 2x ;
2x - 0.4x
Raul:
Divides Number of miles by 5 ; x / 5
Multiplies result by 8 ;
8 * (x/5) = 8x /5
To know if expressions are equivalent :
Let x = 10 miles
Using Arlene's expression:
2x - 0.4x
x = 10
2(10) - 0.4(10) = 16
Using Raul's expression :
8x / 5
(8*10) / 5
80/5
= 16
Since they give the same result, we can conclude that the expression are equivalent
Answer:
529 feet squared
Step-by-step explanation:
We know that the sides of a square are all the same length, and the formula to find the area of a square is length time width, so to find the area of the square we multiply 23 by 23, or square 23. 23 times 23 equals to 529 so the area of the square is 529 feet squared.
Your answer would be 13.4 if you round to the nearest tenth.
