In the first one the answer is letter B, if you divide 255 by 3 is gonna give you 85 then multiply 85 x 50 and its gonna give you 4,250. Let me know if im good or wrong. Have a great day :)
You can get the number by dividing 19.2 by 0.40
The number is 19.2/0.40 = 48
So this is ratios
actual height to shadow height=10 to 18=10:18=10/18=5/9
ratio is 5:9
if the shadow height=12 then find actual height
x:12=5:9 since they should be in the same ratio
x/12=5/9
multiply both sides by 12
x=60/9
x=6 and 6/9
x=6 and 2/3
height of person is 6 and 2/3 foot or 6.66ft or 6ft and 8 inches
Answer:
I am not sure how your teacher wanted you to estimate the answer but I solved it for you. Hopefully this helps.
Step-by-step explanation:
7x-y=7
x+2y=6
14x-2y=14
x+2y=6
add both equations
15x=20
x=20/15
x=4/3
x+2y=6
4/3+2y=6
2y=6-4/3
2y=18/3 -4/3
2y=14/3
divide both sides by 2
y= 14/3 divided by 2
y=14/3(1/2)
y=14/6
2y=
