Let no red ribbons=x
no. Of blue ribbons=x+3
No. Of yellow ribb9ns=x+7
Totsl ribbons=28
28=x+x+3+x+7
28=3x+10
3x=28-10
3x=18
X=18/3
X=6
No .of red ribbons=6

No. Of yellow ribbons=x+7=13
Answer:
x= -2
Step-by-step explanation:
7x-3=4x-9
3x-3= -9
3x= -6
x= -2
Answer:
C
Step-by-step explanation:
related equation
-16t^2 + 32t + 20 = 0
-4t^2 + 8t + 5 = 0
Δ/4 = 16 + 20 = 36
t1 = (-4 + 6)/-4 = -1/2
t2 = (-4 - 6)/-4 = 5/2
-16(t+1/2)(t-5/2)
-16(2t+1/2)(2t-5/2)
-4(2t+1)(2t-5)
The amount of money, b, is $140.
Answer:
b = 3/4
Step-by-step explanation:
Hi!!!
You want the value of B. To get that, we have to divide both sides by 16:


Thus the answer to your question is
.
<u>Check:</u>
3/4 * 16 = 3 * 4 = 12.
12 = 12
So we are correct!!!
