Which of the following is the best estimate for 31% of 9? *GIVING 99 Points!*
Marina CMI [18]
Hello! So, when you know your fractions and percents, you know that about 33% equals 1/3. 31 is close to 33, so the best estimate for 31% of 9 is 3. When you solve it on a calculator, 9 * 31% (0.31) is 2.79, which rounds off to 3 when rounded to the nearest whole number. The answer is B: 3.

vovikov84 [41]

Answer:

x = (+ - ) 9

Step-by-step explanation:

x^2 = 81

u know how u can sometimes cancel something out by doing the opposite.

This is one of those times as well. the opposite of ^2 = square root.

so if we take the square root of both sides, this will cancel out the^2 on the left side.

sqrt (x^2) = sqrt(81)

x = (+-) 9.....thats a positive and a negative sign...because the sqrt of 81 is both 9 and -9.
