i think its d! hope that helps! is that flvs?
Answer:
$240
Step-by-step explanation:
Let x = the original price:
x - 0.2x = 192
0.8x = 192
x = 240
Answer:
As this triangle is being transformed by rotation, the angles will stay same as well as the sides and other details, if you are doing this on a coordinate plane, then the points of the triangle would be changed and nothing else
If my answer helped, please mark me as the brainliest!!
Thank You!
The answer is $2.34. I attached an explanation thing below. Forgive my ugly handwriting.
Answer: 160 liters of the
40% solution and 80 liters of the 70% solution will be used.
Step-by-step explanation:
Let x represent the number of liters of 40% antifreeze solution that should be used.
Let y represent the number of liters of 70% antifreeze solution that should be used.
The volume of the mixture to be mixed is 240 liters. It means that
x + y = 240
The 40% antifreeze solution is to be mixed with a 70% antifreeze
solution to get 240 liters of a 50% solution. This means that
0.4x + 0.7y = 0.5(240)
0.4x + 0.7y = 120 - - - - - - - - - - - -1
Substituting x = 240 - y into equation 1, it becomes
0.4(240 - y) + 0.7y = 120
96 - 0.4y + 0.7y = 120
- 0.4y + 0.7y = 120 - 96
0.3y = 24
y = 24/0.3
y = 80
x = 240 - y = 240 - 80
x = 160
