Answer:
26x-67-x²
Step-by-step explanation:
We are given
Expanding (x-8)²=x²-16x+64
10x-3-(x²-16x+64)
10x-3-x²+16x-64
26x-67-x²
(5x-3)/4 = x/3 +1
5x-3 = 4x/3 +4
5x - 4x/3 = 7
(11/3)x = 7
x = 7/(11/3) = 21/11
If we set the unknown distance (in miles) as x, then we set up an equation according to the data, we can solve for x.
Time taken to go to resort : x/48
Time taken to return : x/40
Total time = x/48+x/40 = 11
Solve for x
common multiple between 48 and 40 = 240
so
5x/240 + 6x/240 = 11
(5x+6x)/240 = 11
11x = 11*240, => x=240
Distance from home to resort is 240 miles
Answer:
4/6 is more than 5/12
Step-by-step explanation:
First, set the denominators of the fractions equal to eachother to make it easier to compare. mulitiply 6 and 4 by 2 so that the denominator now equals 12, and you have the new fractions 5/12 and 8/12. Since 8/12 is more than 5/12, 4/6 is more than 5/12.
Answer:
The answer is x = 14 the more expensive scarf
Step-by-step explanation:
x + y = 25
3 + y + y = 25 (x = 3 + y)
3 + 2y = 25
2y = 25 - 3
2y = 22
y = 22/2
y = 11
x = 3 + y
x = 3 + 11
x = 14 (the more expensive scarf)
(x,y) ; (14,11)
