Answer:
m= -5/3
Step-by-step explanation:
M= slope
To find slope, you do y= mx + b
First lets put these numbers into improper fractions. 4 2/5 becomes 22/5 becomes we multiple the 4 by the denominator,5, and add to the dividend.
We do the same process with 16 1/2 and get 33/2.
We then need to set these equations so that they have the same base. In these case a common factor is 10.
We multiple our first equation by 2 and get 44/10, and then we multiple our second equation by 5 and get 165/10.
We then setup the equation (44/10)*x=165/10
We can multiple each side out by 10, leaving us 44x=165
Divide each side by 44, which leaves us with x=165/4
When you simiplify the problem we are left with x and our answer.
When done correctly you will find that it takes 3 3/4 minutes to fill a tank that holds 16 1/2 gallons.
Answer:
Step-by-step explanation:
To solve for the given variable 
, we need to get on one side of the equation by itself. To do so, we need to remove the -16 that is on the same side of the variable.
To get rid of the -16, we can add a 16 to that side of the equation since 
, which will get by itself; however, if we add -16 to one side of the equation, we must add it to both sides of the equation:
Answer:
y = 1
d = 4
Step-by-step explanation:
8y - 2d = 0 ---------------(I)
5y + 4d = 26 1/4
5y + 4d = 105/4 ------------------(II)
(I)*2 16y - 4d = 0
(II) <u>5y + 4d = 105/4</u> {add (I) &(II)}
21y = 105/4
Substitute y =1 in equation (I)
8*1 - 2d = 0
8 - 2d = 0
-2d = -8
d = -8/-2
d = 4
