if you multiply the amount of sugar for one batch (1/2 cup), and the amount of batches you are making (7) you will get the answer.
Answer:
4x+5y=20
Step-by-step explanation:
bc if u subtract your 4x from both sides
then u should end up with 5y= -4x+20
then u divide the 5 from everything
then you end up with y= -4/5x+4
Answer:
y = -2x - 8
Step-by-step explanation:
Slope-intercept form is y = mx + b. Slope is m, and y-intercept is b. To do this, we substitute -2 for m and -8 for b. When we do this, we get y = -2x + -8. We can simplify this to y = -2x - 8.
62=2w+2l
120= 2(2w)+ 2(l+21)
120=4w+2l+42
78= 4w+2l
39=2w+l
39-2w=l
Use substitution
62=2w+2(39-2w)
62= 2w+78-4w
62= -2w+78
-16=-2w
8=w
Plug w in
62=2(8)+2l
62=16+2l
46=2l
23=l
Final answer: Width=8, Length=23
