Answer:
dryer cost = $450
Step-by-step explanation:
Given that:
washer + dryer = $841 ---- eq1
As washer costs $59 less than dryer So,
Dryer - $59 = washer
putting in eq1
Dryer + dryer - $59 = $841
2 dryers = $841 +$59
Dryer = $900/2
Dryer = $450
So the cost of washer will be:
washer = dryer - $59
Washer = $450 - $59
washer = $391

Answer:
This is a reflection about the x-axis.
Step-by-step explanation:
A reflection about the x-axis has the rule
[x,y]-> [x,-y].
Therefore
M[x,y] = [x,-y}
Let M=
|a b|
|c d|
Then the matrix multiplication gives
ax+by=x.............(1)
cx+dy=-y............(2)
Solving the previous equations (1) and (2) gives
a=1, b=0
c=0, d=-1
giving M as
|1 0|
|0 -1|
Answer:
Step-by-step explanation:
3/5 divided by 7/10
You use KCF
KCF stands for keep change flip
So it would be 3/5x10/7
3 10 15
_ x _ = _
5 7 7
you need to simplify it so the 5 in 3/5 would be a 1 and the 10 in 10/7 would be 5
