Answer:
$398 and $796
Step-by-step explanation:
w = cost of the washer
d = cost of the dryer
w + d = $1194
w = 2d
Substitute the w into the first equation.
2d + d = $1194
3d = $1194
d = $398
Substitute d into either equation.
w=2(398)
w=$796
Answer:
A. 1,500m
B. 2000m
C. 1875m
Step-by-step explanation:
A. Here, we simply substitute the value of t in the equation.
t = 5min
V(t) = 400 - 20t
= 400 - 20(5)
= 400 - 100 = 300m/min
Now we know that distance = speed * time = 300 * 5 = 1,500m
2. Substitute t = 10
V = 400 - 20(10) = 400 - 200 = 200m/min
Distance = speed * time = 200 * 10 = 2000m
3. Here we need to calculate time
Rearranging the equation:
20t = 400 - V(t)
20t = 400 - 250
20t = 150
t = 150/20 = 7.5min
Distance traveled = 250 * 7.5 =1875m
Answer:
x = −1/13 and y = 33/13 or 2 7/13
Step-by-step explanation:
x+2y=5
x+2(6x+3)=5
x+12x+6=5
13x+6=5
-6 -6
13x= -1
/13 /13
<u>x= -1/13</u>
y=6x+3
y=6(-1/13)+3
y= 33/13
y= 2 7/13
3*9= 27
23/9= 2.5
If they have the same number of chickens.
