Answer:
13
Step-by-step explanation:
Set Susan's present age as x, her age from 3 years ago as x-3, and her age in three years as 2(x-3)
Since her age in seven years = 2 times as old as she way 3 years ago, set up the equation:
x+7 = 2(x-3)
x+7 = 2x-6
x = 13

Answer:
The answer to your question is Area = 6 u²
Step-by-step explanation:
Process
To find the area of the picture divide the figure between a square and a right triangle, determine the area of each figure and finally add them up.
1.- Calculate the area of the square
Area = side x side
= 2 x 2
= 4 u²
2.- Calculate the area of the triangle
Area = base x height / 2
base = 2 height = 2
Area = 2 x 2 /2
Area = 2 u₂
3.- Total area
Area = 4 + 2
= 6 u²
Answer:
86%
Step-by-step explanation:
<u>430</u><u> </u> × <u>100</u> = <u>430</u> = 86%
500 1 5
you are going to cancel. 100 divided by 100 leaves 1. 500 divided by 100 is 5.
430×1= 430. 5×1=5. divide 430 by 5 and you"ll get 86.
