Answer:
Each hat is $5
Each mask is $3
Step-by-step explanation:
Hat= x dollars
Mask= y dollars
Now,
3 hats and 4 mask sold = $27
We can write
3x + 4y = 27
Adding the second equation (-1 times 1st equation) gives us;
3x + 6y = 33
-1* (3x + 4y = 27)
3x + 6y = 33
-3x -4y = 27
2y = 6
y = 6/2
***y = 3***
Now we replace y= 3 into 1st equation and solve for x:
3x + 4y = 27
3x + 4(3) = 27
3x + 12 = 27
3x + 15
x = 15/3
***x= 5***
Each hat costs $5
Each mask costs $3
Answer:
The slope is 7/7 or 1.
Step-by-step explanation:
Find any two points on the line. I chose (0,7) and (-7,0).
Put rise over run.
7-0
———
0 – -7
this would equal 7/7 which simplifies to 1.
Hope this helped!
You need to multiply 25 by 8 so the answer well be 200
