7 = 07
Assuming you mean 10 °C higher... 3 °C (or +3 °C) is 10° higher than -7 °C
.9 is farther from 0 on the number line in the positive direction than .7. Thus, .9 is higher (or greater than) .7 Alternatively, .9-.7 = .2, a positive number. Since the difference is positive, the first number must be greater than the second
You add an positive number to .07. The answer is greater than .07
No 0.51 is closer to the decimal point as in 0.51 is 51/100 whereas 0.07 is only 7/100 so 51 is bigger than 7 basically
No, but .07 is less than 7.
5
It is normal for an alkaline solution to have a pH higher than 7.
10 degrees higher than -7 degrees is 3 degrees.
051 as in 51 is bigger than 7
7 - 07 = 7You may have meant:7 - .07 = 6.93

No.
It is difficult to answer without knowing exactly where the decimal point is in 07 so here are the three options. .07 is less than 0.15 0.7 is greater than 0.15 7 is greater still.
7 = 07
No, 7 is neutral. Higher than seven is a base, and lower than 7 is an acid.
