Hi Quanzia25,
Solution:
45mph
45mph x 4hrs. = 180 miles in 4 hours
45 / 3 = 15
180 + 15 = 195
Answer:
The car has traveled 195 miles.
84-6-4=72
48/4=12. 84-12= 72
84 - (48/(8-4)) = 84 - (48/4) -4 = 72
84 - 12 = 72
Answer:
top left
Step-by-step explanation:
5x + 300y = 178
4x + 500y = 197
Multiply the first equation by 5 and the second equation by -3.
25x + 1500y = 890
-12x - 1500y = -591 Subtract.
------------------------------
13x = 299 Divide.
x = 23.
Solve for y by plugging in 23 for x.
4(23) + 500y = 197
92 + 500y = 197
500y = 105
y = .21
The Daily Fee is $23 and the Charge Fee per mile is $0.21.
So if you multiply 15 and 10 by .2 or (1/5) you would get 3 and 2 then find the area which would be 6 then 6/150 to get what its multiplied by so the area of the new rectangle would be multiplied by .04
