There are 6 boys for every 18 girls. 1:3 ratio. 6:18 = 1:3
3x+y=16 because it adds 3 each time so 13+3=16
Answer:
Perimeter: 18 Area: Unknown
Step-by-step explanation: Add all the sides together, 2+4+4+8= 18
Area is length x width, and we do not know which numbers are the length or width.
Answer:
x=-3/2
Step-by-step explanation:
-3(x+2)+5x=-9
-3x-6+5x=-9
2x-6=-9
2x=-9+6
2x=-3
x=-3/2
Answer:
4 yellow rosebushes
Step-by-step explanation:
Givens(What the question tells us):
m = 3(There are 3 multicolored bushes)
r + y + p = 15 - m( total red bushes plus total yellow bushes plus total pink bushes equals 15 - the amount of multicolored bushes)
r = y = p (total red bushes equals total yellow bushes which also equals total pink bushes)
Since we know m =3 we can substitute m for 3 in the second equation:
r + y + p = 15 - 3.
r + y + p = 12
Now since r, y, and p are equal we can divide the total amount left (12) by the 3 kinds of roses left to get our answer:
12/ 3 = 4 red, 4 yellow, and 4 pink
Since we are solving for the amount of yellow the answer is:
4 yellow rosebushes
