2x + 10 = 2(3x - 7)
2x + 10 = 6x - 14
4x = 24
x = 6
3x - 7 = 3(6) - 7 = 11
2x + 10 = 2(6) + 10 = 22
Answer:
17
Step-by-step explanation:
Let the number be x.
We know that 3x=51
If we divide both sides by three, we get x=17
If you interpret the question as is, the answer is in the thousands, which is not listed. The last part of the question should read 'the number of new cases doubled from those newly identified cases from the day prior. The question is very poorly phrased.
Day 1 : 5
Day 2: 5 + 10
Day 3: 15 + 20
Day 4: 35 + 40
Day 5: 75 + 80
Day 6: 155 + 160
Which is 315 at the end of 6th day
It's the bottom one. Miko found the incorrect and checked her work using multipication incorrectly.
This is because the correct way to solve this would to use (5/1) * (3/5) = (15/5) then simplify it to 3/1 or simply 3.
Dividing fractions is simply flipping the second fraction and then multiplying across
If you mean minus, the answer is 36.
