Y= 2.75 add 3 to both sides and divide by 2 (2y - 3 = 2.5)
x= 4.5 subtract 8 from both sides and divide by 6 (6x + 8 = 35)

Answer:
The answer to your question is 16/49
Step-by-step explanation:
Data
4/7 ÷ 1 3/4
Process
1.- Convert the mixed fractions into improper fractions
1 3/4 = (4 + 3) / 4 = 7/4
2.- Divide
4/7 ÷ 7/4 = 16/49
3.- Simplify
I think it is not possible to simplify.
4.- Also we can solve this problem by converting the division into a multiplication, just invert the second fraction.
4/7 x 4/7 = 16/49
The result is the same.
Answer:
Calculate the skid speed by multiplying the drag factor times the braking efficiency times the skid distance times 30 and taking the square root of the result. For example, if the car skidded 120.5 feet on a road with a drag factor of 0.5 and left four skid marks, the car was going about 42.51 mph.
Step-by-step explanation:
2x multiplies to all numbers:
2x x 8x3 = 16x4
2x x 6x2 = 12x3
2x x -10x = -20x2
Answer: 16x4 + 12x³ - 20x²
Hope this helps :)
