Answer: 4 pounds of wooden blocks and 6 pounds of plastic bricks should be used.
Step-by-step explanation:
Let x = Quantity of wooden blocks.
y = Quantity of plastic bricks.
As per given , we ahve
5x+10y=80 (i)
x+y=10 (ii)
Multiply 5 on both sides of (ii), we get
5x+5y=50 (iii)
Eliminate (i) from (iii), we get
5y=30
⇒ y= 6
Put y=6 in (ii), we get
x+6=10
⇒ x= 10-6= 4
Hence, 4 pounds of wooden blocks and 6 pounds of plastic bricks should be used.
Dimensions of the logo:
W = 4 in, L = 6 in
Dimensions of the billboard:
W ( Billboard ) = 4 x 15/2 = 2 x 15 = 30 in
L ( Billboard ) = 6 x 15/2 = 3 x 15 = 45 in
Answer:
D ) 30 in by 45 in
Answer:
Step-by-step explanation:
let s be speed and t be time taken
s*t=649
(s+8)(t-4)=649
st-4s+8t-32=649
-4s+8t-32=0
4s=8t-32
s=2t-8
2t=s+8
t=4+s/2
