Answer:
Step-by-step explanation:
To add or subtract two or more fractions from each other, the denominators have to be the same. To make the denominators the same, we should find the least common multiple of 5 and 7. The least common multiple of 5 and 7 is 35. 5 should be multiplied with 7 to get 35 and 7 should be multiplied with 5 to get 35 (with both numerators).
When subtracting, only subtract the numerators (the denominators are kept as is).
Let, the number = x
It would be: 8x + 3 = 3(2x-1)
8x + 3 = 6x - 3
8x - 6x = -3 - 3
2x = -6
x = -6/2
x = -3
In short, Your Answer & that number would be -3
Hope this helps!

Answer:
109.3 yard²
Step-by-step explanation:
Area of triangle = bh / 2
base is 23yd
height is 9.5yd
bh / 2 = 23 × 9.5 / 2
Area = 218.5 / 2
Area = 109.25 yd²; rounded to the nearest tenth is 109.3yd²
