In other words it is 1 1/2
50,779/590 is 90.7125 but rounded to 90.71
Answer:
x=5.2
Step-by-step explanation:
8x−14=7.7x+3x
Step 1: Simplify both sides of the equation.
8x−14=7.7x+3x
8x+−14=7.7x+3x
8x−14=(7.7x+3x)(Combine Like Terms)
8x−14=10.7x
8x−14=10.7x
Step 2: Subtract 10.7x from both sides.
8x−14−10.7x=10.7x−10.7x
−2.7x−14=0
Step 3: Add 14 to both sides.
−2.7x−14+14=0+14
−2.7x=14
Step 4: Divide both sides by -2.7.
−2.7x
/−2.7 =
14
/−2.7
x=−5.185185 or 5.2
14.99n+4.99 represents the cost of n cds
(14.99x3) + 4.99 =
34. 97 + 4.99= $39.97- 0.1= $39.96
3 CD s cost $39.96
To find the answer,we can set up two equations:
Let the integer be x and y seperately,and x be the larger number:
x+y=74
y=74-x....(1)
x-2y=26...(2)
Put (1) into (2):
x-2(74-x)=26
x-148+2x=26
3x=26+148
x=174/3
x=58
Put the above answer into (1):
y=74-58
y=16
Therefore,the answer is x=58, y=16.
Hope it helps!
