Answer:
Step-by-step explanation:
600 miles
30=1 inch
600/30=20 inches
500/25= 20 cm
225/25= 9 cm
<span>a(c−b)=d
ac - ab = d
ac = d + ab
c = (</span>d + ab) / a
answer is
D. c = (d + ab) / a
The answer is -i. I hope that helps.
Answer:
17. A positive slope moves upward on a graph from left to right. A negative slope moves downward on a graph from left to right.
18. Zero slope means that the line is horizontal. Just like the line that makes the top of a “Z” is horizontal. No slope means that the line is vertical.
19. Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or the change in the y values over the change in the x values. The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2.
20. Yes, they did because 2/6 is equivalent to 1/3.
21. A negative slope means that two variables are negatively related; that is, when x increases, y decreases, and when x decreases, y increases. Graphically, a negative slope means that as the line on the line graph moves from left to right, the line falls.
Answer:
4/7
Step-by-step explanation:
Let's start by moving like terms to one side. Remember that when you change the side of a term, the sign flips.
-5x-2x=-3-1
-7x=-4
Divide both sides by -7
x=4/7
