Answer:
-1/2
Step-by-step explanation:
The equation is in slope intercept form:
y=Mx+b
where m is the slope and b is the t intercept
Compare y=Mx+b to the equation y=-1/2x-5
-1/2 is being multiplied by x, so it is the slope.
Answer:
Number of white marbles in the bag = 45
Step-by-step explanation:
Total number of marbles in the bag = 135
Ratio of white marble to transparent ones = 3 : 6

I think it is C. Sorry if I'm wrong.
Step-by-step explanation:
x=1.25y
perimeter= 2width+2length
olivias p=ryan's p so:
Ryan's p= 2*1.25 Ryan's width+ 2Olivias length
Olivias length= (2,5Ryan's width- Ryan's p)/2
Answer:
that's the simplified way 24×15×38
