Answer:
7⁵-3=7⁵x- 19
Step-by-step explanation:
16807 - 3 = 7⁵x - 19
16804 = 7⁵x - 19
16804 = 16807x - 1
adding 19 on both sides
16804 + 19 = 16807x - 19 + 19
16823 = 16807x
x = 16823 / 16807
16823 upon 16807 is the x
The correct answer is y=4x-1
Answer: 12.25
Explanation:
If you read 4.8 out loud it should be "four and eight tenths." This is always a good start when changing a decimal into a fraction. 4 8/10 is a mixed number, so to further simplify it as a mixed number we leave the 4 alone and reduce the fraction 8/10. So we can reduce 8/10 to 4/5. Then you bring the 4 back and put 4/5 with it. So 4.8 as a fraction is 4 4/5.
