If 5+ 20-22-3x – 10.2-2x + 5, what is the value of x?
-3
-2
2
3

3

Step-by-step explanation:

Step 1: get rid of the +5 on both sides.

Step 2: divide by 10 on both sides

Then you have: 2*2^(2-3x) = 2^(-2x)The factor 2 on the left can be brought into the exponent because you're simply multiplying with 2 more...2^(1+2-3x) = 2^(-2x)Now you can equate the exponents:3-3x = -2x => 3 = -2x+3x => x=3

so D is your answer.

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
