Work out the equation backward.
22-4=18
18/2=9
The original number was 9
2 1/5 + 6 4/5 = 9 <span> 6 5/12 - 2 1/12 = 4.3 </span>11 8/9 + 4 1/3 = 16.2 <span>7 1/6 - 5 3/4 = 1.41
</span>11/18 + 6 1/10 = 6.71 <span>15 1/3 - 2 5/8 = 12.7083</span>
Answer:
see below
Step-by-step explanation:
1. 7x+2x+19x
(7, 2, 19) x
=28x
2. -6x-3+3x-9
-3x-3-9
=3x-12
3. (3x-4y) -(x+2y)
3x-4y-x-2y
=2x-6y
4. 18x5 - 6x3
90-18
=72
5. (x+5)(x-7)
x²-7x+5x-35
=x²-2x-35
=x^2-8x+16-16
= (x-4) ^2-16
=[(x-4) -4][(x-4) +4]
=(x-8) x
Answer:
1/16
Step-by-step explanation:
The ratio of the perimeters is 1/4
Therefore re area of the ratio of the areas can be calculated as follows
= 1/4^2
= 1/16
