Answer:
Y=7/3x+3
Step-by-step explanation:
you start at the y intercept which is b. you would then do a rise over run, starting with the lowest value ont the grid. you will count 7 up, and then you do run, which is counting across. you will get 3. your answer is y=7/3x+3
Answer:
- 5
Step-by-step explanation:
Step 1:
4 ( 2y + 1 ) = 2 ( y - 13 )
Step 2:
8y + 4 = 2y - 26
Step 3:
6y + 4 = - 26
Step 4:
6y = - 30
Answer:
y = - 5

Answer:
Step-by-step explanation:
Okay so lets put the x values on one side and the whole numbers which are the numbers without variables on the right side.
so now,
m/9 = -2/3 + 7/3
now lets use the inverse operation of division to multiply 9 to separate it from the variable
9(m = -2/3 + 7/3)9
m = -18/3 + 63/3
which can be simplified to,
m = -6 + 21
so,
m = 15.
Hope this helps!
x+ y = 96 → y = 96 - x (1)
And the price per plain cake * the number he sold + price of the decorated cake * the number he sold = total sales
So
8x + 12y = 800 (2)
Subbing (1) into (2), we have that
8x + 12 (96 - x) = 800 simplify
8x + 1152 - 12x = 800
-4x + 1152 = 800 subtract 1152 from both sides
-4x = -352 divide both sides by -4
x = 88 = the number of plain cakes he sold
And 96 - x = 96 - 88 = 8 = the number of decorated cakes he sold
