Answer:
x + 1
Step-by-step explanation:
3x - (2x + 4) + 5
3x - 2x - 4 + 5
x - 4 + 5
x + 1
3×2+14=20
20×3+18=78
78×4+22=334
334×5+26=1696
1696×6+30=10206
Hence, the question mark should be replaced by 10206
Answer: False
Explanation :
Although basalt is very acidity due to its non calcareous nature, it is made up of grains that are so fine that they are impossible to differentiate without the aid of a microscope (that is they can't be seen with the naked eyes or even with the use of magnifying lens), but this it's features are very different from that of granite which is composed of crystals of the four particles hornblende, quartz, feldspar, mica big enough to be easily seen without a microscope.
Solutions

Calculations
20 - 14 = 6
He saves $ 6 each week.
Now we have to find how many times 6 goes into 300. To do this we have to divide.
300 ÷ 6 = 50
<span>It is going to take him 50 weeks. </span>
