Step-by-step explanation:
<u>5 teachers for every 115 students </u>
- 1 teacher for every 115/5 = 23 students
<u>3 tutors for every 27 students</u>
- 1 tutor for every 27/3 = 9 students
<u>If there are 90 students, then number of tutors:</u>
Answer:
(1): "x7" was replaced by "x^7". 1 more similar replacement(s).
Equation at the end of step 1
(0 - (3 • (x5))) • (2•3x7)
Equation at the end
(0 - 3x5) • (2•3x7)
Multiplying exponential expressions
3.1 x5 multiplied by x7 = x(5 + 7) = x12
Multiplying exponents:
3.2 31 multiplied by 31 = 3(1 + 1) = 32
Final result :
( -32•2x12)

Answer:
Look below
Step-by-step explanation:
1) x = 14, because 14 * 14 = 196
2) x = 3 / 16, because ( 3 / 16 ) * ( 3 / 16 ) = 9 / 256
3) x = 8, because 8 * 8 * 8 = 512
4) x = 4 / 7, because ( 4 / 7 ) * ( 4 / 7 ) * ( 4 / 7 ) = 64 / 343
