This question belongs to simple algebric equation, where we need to add or subtract fractions by finding a common denominator.
Given total hours = 120
Number of hours tutored for 1st week =2 1/3 hours = 7/3 hours
Number of hours in the 2nd week = 3/2 = 1.5 hours
Let the number of more hours she needs to teach be x
=
23 + 6x = 120
6x = 97
x = 16.167
Hence Kiara needs 16.167 more hours.
And this belongs to a part-whole problem, because the time she still needs to tutor is unknown.
Answer:
29.1
Step-by-step explanation:
Use logic.
Jk. Tan(x) = 5/9 so x = tan^-1(5/9)
Use a graphing calculator in degrees mode.
A double negative equals a positive so this is essentially:
-34+55
Of which equals 21
Answer:
y=3 x=-20
Step-by-step explanation:
2(3y-5)+12y=-4
6y-10+12y
18y-10=-4
18y=6
y=3
2x+12(3)=-4
2x+36=-4
2x=-40
x=-20
