Answer:
For the first example, the constant of proportionality should be .4 of a mile, meaning that Li can run .4 mile per minute. The equation should be .4x = y. For the second example, it is easy to find the constant of proportionality because it is given, which is 2. The equation to represent this would be 2x = y.
Step-by-step explanation:
The reason why the constant of proportionality is .4 is because I used the ratio from before and compared it to the one needed. I simply turned the ratios into fractions and I cross multiplied before turning it into a equation to solve to find .4 as the constant of proportionality. The equation should be .4x = y because x = the amount of minutes Li ran, and y = the total amount of miles she ran. The reason why the constant of proportionality is 2 in the second problem is because Jennifer is paying 2 per pound, which is the unit rate. If we are looking at the cost per pound, it would mean that 2 is the constant of proportionality. The reason why the equation to represent this would be 2x = y is because x = the amount of pounds, and y = the total amount of money, which represents the situation.
Answer:
S,Z and W,X
Step-by-step explanation:
If you look at your number line, you will see that point Z (20) is positive and point S (-20) is negative. The opposite of a positive is a negative, which makes -20 and 20 opposites. This goes for -5(W) and 5(X) as well.
Answer:
<1 = 54
Step-by-step explanation:
< CAB = <1 + <2
We have to assume that AP is a perpendicular bisector or we cannot solve the problem.
That would mean that <1 = <2
11x+9 = 6x+6x
11x+9 = 12x
Subtract 11x from each side
9 = 12x-11x
9 =x
We want <1
<1= 6x
<1 = 6*9
<1 = 54
