6:57
Add 3 minutes to it and subtract 3 from the elapsed time.
6:57 + 3 = 7:00
47 - 3 = 44
Now add 44 to 7:00:
7:00 + 44 = 7:44
Answer:
length = 14 feet
Step-by-step explanation:
112/8 = 14 feet
Width =3.5, length = 4
Let's make a few equations to summarize what we know.:
a = 14
l = 2w -3
a = wl
Now let's substitute the expression for l into the expression for area and solve.
a = w(2w - 3)
a = 2w^2 - 3w
14 = 2w^2 - 3w
0 = 2w^2 - 3w - 14
which factors into
(2w - 7) (w + 2)
Solving for w
2w - 7 = 0
2w = 7
w = 3.5
w+2 = 0
w = -2
So w can be either 3.5 or -2. Since a negative width doesn't make sense, w = 3.5
Let's verify
w = 3.5
l = 2w - 3
l = 2*3.5 - 3
l = 7 - 3
l = 4
a = wl
a = 3.5 * 4
a = 14
So the width is 3.5 and the length is 4.
Sounds like 18 servings to me.
6 quarters go into 1.5
6 x 3 is 18 so 18 servings.
Answer:160=40+10x
Step-by-step explanation:
160=40+10x
40+10x means he paid $40 first,and he his going to pay the balance 10x,
160-40=120
He his going to pay $12
