33 + 15w = 3w -w + 4w
Answers
3w minus w is 2w, +4w is 6w. subtract 15 w both sides of the equation to get 33 on one side, and 9w on the other side. divide 9 on both sides, and the nswer is 3 and 2/3.
First, start by adding like variables on the same side of the equal sign
- 33+15w= 2w+4w
- 33+15w= 6w
Next, subtract 15w from both sides to get like terms on the same side
- 33+15w(-15w)=6w(-15w)
- 33=-9w
Finally, divide -9 on both sides to get the variable alone
- 33(/-9)=-9w(-9)
- 24=w or w=24

Down-fill sleeping bags(y) = 5
Polyester-fill sleeping bags (x) =9
Step-by-step explanation:
Hi, the sum of the product of each type of sleeping bag multiplied by its cost is equal to 1456 (equation1)
The sum of both sleeping bags sold is equal to 14 (equation 2)
A.
x 79 + y149=1456
x +y = 14
B. multiplying the second equation by 79 and subtracting it to the first equation.

_____________
70y = 350
y = 350/70
y = 5
C. solving for x in the second equation:
x = 14-y
Replacing x in the first equation:
79 (14-y)+ 149y=1456
1106-79y +149y =1456
149y-79y = 1456-1106
70y =350
y = 350/70
y = 5
D:
Replacing the value of Y in any equation:
x +y = 14
x+ (5) =14
x =14-5
x = 9
Down-fill sleeping bags(y) = 5
Polyester-fill sleeping bags (x) =9
x+y=14
79x+149y=1456

Answer: 230 pitchers.
Step-by-step explanation:
Given: Gavin has baseball players in his collection of base ball cards = 460
Percent of players which are pitchers= 15%=0.15
The number of pitchers there are in Gavin's collection
Therefore, the number of pitchers there are in Gavin's collection=230
Hence, there are 230 pitchers in Gavin's collection.
number of pitchers = 15/100 * 460 = 69

if we imagine a graph in our head
we see that the graph goes down, negative slope
it goes down 4 units and to right 6, so 4/6=2/3 but it is negative so -2/3
other way is
(y2-y1)/(x2-x1)=(0-4)/(6-0)=-4/6=-2/3
