On enlarging the rectangle, the proportion or ratio of Length to Height will stay the same.
The ratio of original length to height is 13 : 6
The ratio in enlarged rectangle will stay the same. Let the height of enlarged rectangle is y cm. So we can write:
Therefore, the height in enlarged rectangle will be 9 cm
The numbers arer 3 and 10
10x10=100
3x3=9
100-9=91
Answer:
He messed up on x + 2 = 5 (when he divided both sides by 3.)
He is first supposed to subtract 2 from both sides and you would get 13. Then you would divide both sides by 3 which would get you 4.33 repeating.
Answer:
Lets work through it.
1. Distribute values:
2/3x-4=6
2. Move variables to one side
2/3x=10
3.Divide by 2/3 or multiply by 3/2
x=10*1.5
4. Answer=1.5
