Answer:
the dryer costs $425
Step-by-step explanation:
x = washer
y = dryer
x + y = 803
x = y - 47
using the second equation a substitute in the first equation we get
y - 47 + y = 803
2y = 850
y = $425
FYI
x = y - 47 = 425 - 47 = $378
Answer:
Step-by-step explanation:
The satellite has 30 modular units.
There are equal numbers of non-upgraded sensors in each unit.
Let us assume that on the entire satellite there are x numbers of upgraded sensors.
Then as per the given condition, there are number of non-upgraded sensors in one unit.
Therefore, the number of non-upgraded sensors on the entire satellite is =6x
Hence, total number of sensors in the satellite is (x+ 6x) =7x
Therefore, the required fraction of the upgraded sensors is . (Answer)
Two decimals
8.4
5.7
Now add
Those two decimals to get 14.1
8.4
+5.7
14.1

7,134 + d = 10,000
Subtract 7,134 from each side:
d = 10,000 - 7,134
d = 2,866
