Answer:
7,000
Step-by-step explanation:
The number of actual steps is x.
x + x(.05) = 7350 This is actual steps plus the extra 5% equals the number shown on the tracker.
Pull out x
x (1+.05) = 7350
x (1.05) = 7350 Divide by 1.05
(x (1.05))/1.05 = 7350/1.05
x = 7,000
Answer:
Look in explanation.
Step-by-step explanation:
1. 
is the same as 
because since there is a negative exponent, you would want to flip the reciprocal and change the negative to positive.
The rest are very similar to this.
Answer:
x = 29 1/3 degrees
Step-by-step explanation:
A triangle has 3 angle that total 180 degrees.
The three angles given are 82 degrees ,2x+10 degrees and x degrees.
So,
82+ (2x+10) + x = 180
Combine like terms.
92 + 3x = 180
Subtract 92 from each side
3x = 180 -92
3x = 88
divide each side by 3
3x/3 = 88/3
Change 88/ 3 to a mixed number
3 goes in to 88 29 times with 1 left over.
x = 29 1/3 degrees
1. 1650 / 55 = 330 / 11 = 30
2. 5634 / 18 = 939 / 3 = 313
3. 6440 / 28 = 920 / 4 = 230
4. 5256 / 52 = 2628 / 26 = 1314 / 13 = 101.07
5. 1955 / 85 = 391 / 17 = 23
