The answer would be 11 gallons.
The tub starts with 32 gallons. Every minute it loses 3 gallons.
So after 1 minute it has lost 3 gallons. For example:
32-3= 29 Meaning that after 1 minute the tub has 29 gallons left.
Now you have to remember that the tub is draining for 7 minutes. So it is losing 3 gallons 7 times, because it loses 3 gallons each minute and there are 7 minutes.
We can use multiplication to find how many gallons the tub loses after 7 minutes. This sign “X” basically means “groups of”. We have 7 groups of 3, or
7 X 3
This is the same as saying we have 3, 7 times. Written like this:
3+3 +3 +3 +3 +3 +3 = 21
So after 7 minutes the tub has lost 21 gallons.
Now we take the original number of gallons and take away what was lost:
32-21=11
So there are 11 gallons left after 7 minutes.
Please let me know if you need any further explanation. Hope this helped.
Hey, the answer is 36 birds. The equation is "0.25x - 2 - 3 = 4"
We have 0.25x because x resembles the amount of birds that were there in the beginning. A fourth flew away, which explains the 0.25 or one-fourth. After that, 2 birds flew away, followed by another 3.
Let the cost of each bun in 8 count package is x and the cost of each bun in 10 count package is y.
It is given that the unit price of an 8-count package of hamburger buns is $ 0.03 more than the unit price of a 10-count package. So we can write the equation:
x = y + 0.03 (1)
The 8-count package costs $0.45 less than the cost of the 10-count package. We can write this in equation as:
8x = 10y - 0.45 (2)
Using the value of x from (1) in equation (2) we get:
8(y + 0.03) = 10y - 0.45
8y + 0.24 = 10y - 0.45
0.24 + 0.45 = 10y - 8y
0.69 = 2y
y = $ 0.345
This means the unit price of 10 count package of hamburger buns is $ 0.345. So the cost of entire pack will be 10 x 0.345 = $ 3.45
Thus, the cost of 10-count package is $3.45
We can assume that it is aline
y=mx+b
m=slope
b=yintercpt
if you have th epoints (x1,y1) and (x2,y2)
slope=(y2-y1)/(x2-x1)
pick any 2 points
(1,2) and (2,5)
slope=(5-2)/(2-1)=3/1=3
y=3x+b
solve for b
sub a points
(x,y)
(0,-1)
-1=3(0)+b
-1=0+b
-1=b
the equation is y=3x-1
or infunction form
f(x)=3x-1
Answer:
11 panels is 13,750
Step-by-step explanation:
3,750- 2,500= 1,250
1,250 x 11 = $13,750
