Answer:
5 1/3= (3*5+1)/3=16/3
3 3/4=(4*3+3)/4=15/4
16/3: 15/4=16/3*4/15=64/45=1.422
Step-by-step explanation:
The first one is 17.7 after rounding off
a2+b2=c2
b2=19^2-7^2
b=17.664
The second one is 108
Volume of a prism=base area x length
=(1/2 x12.6x1.6) x 10.75
=108.36mm3
The next score is 90 because 85+91+92+92=360/4= 90 average.
12 would be right since 3-12 would be 9 then 9 times 2 is 18.
Answer:
B and F
Step-by-step explanation:
If we take the equation given and work out the problem, then we are able to see the equations that match it. Here is the work:
![-9(\frac{2}{3} x+1)\\-9(\frac{2}{3} x) + -9(1)\\-\frac{9}{1} *\frac{2}{3}x -9\\-\frac{18}{3}x -9\\ -6x-9\\](https://tex.z-dn.net/?f=-9%28%5Cfrac%7B2%7D%7B3%7D%20x%2B1%29%5C%5C-9%28%5Cfrac%7B2%7D%7B3%7D%20x%29%20%2B%20-9%281%29%5C%5C-%5Cfrac%7B9%7D%7B1%7D%20%2A%5Cfrac%7B2%7D%7B3%7Dx%20-9%5C%5C-%5Cfrac%7B18%7D%7B3%7Dx%20-9%5C%5C%20-6x-9%5C%5C)
Hope this Helps!
