100/5= 20
20 x 4 = 80
80 + 43 = 123
if my math is correct then none are correct
(prolly a typo)
It is easier (for me anyway) to find 10% then work around that.
Following that path would mean that, by making a table:
100% = 220
10% = 22
5% (Which is half the 10) = 11
Answer:
23 starfish, 7 octopi
Step-by-step explanation:
x=starfish
y=octopi
x+y=30
5x+8y=171
-5(x+y=30)
5x+8y=171
-5x-5y=-150
5x+8y=171
3y= 21
y=7
x+7=30
x=23
23 starfish, 7 octopi
Answer:
m= 6-(-4)/-4-0 = -5/2
m=-5/2, the slope.
Step-by-step explanation:
Use the formula m=y2-y1/x2-x1
To find the SLOPE (m) you need to do m=y2-y1/x2-x1
(0,-4) is ordered pair #1, (-4,6) is ordered pair #2
m = 6-(-4)/-4-0
m = -5/2, THE SLOPE.
This is the answer for you.
