Step-by-step explanation:
4/5 gallons for 280 ft² (the ² is missing in the question ...).
3 gallons would be 15/5.
so, what do I need to multiply 4 with to get 15 ?
4×x = 15
x = 15/4
multiplying now also 280 ft² with this factor gives us the answer :
280 × 15/4 = 70 × 15 = 1050 ft²
they can paint 1050 ft² with 3 gallons of paint.

<span>When you add fractions, the denominators must be the same, so you may have to generate equivalent fractions by using the lowest common multiple of all the denominators. For subtraction of fractions, you use the same method. When multiplying fractions, you can only multiply the numerators together, and the denominators together. </span>
Answer:
Slope = -1
Step-by-step explanation:
Since, slope of a line passing through two points 
and 
is given by,
Slope = 
Therefore, slope of a line passing through two points A(1, 4) and B(3, 2) will be,
Slope = 
= (-1)
Therefore, slope of the line is (-1).
