Answer:
= 13.5
Step-by-step explanation:
<u><em>Explanation:</em></u>-
Given that the equation
cross multiplication, we get
= 4.5 × 3
= 13.5
Answer:
1 / 13
Step-by-step explanation:
lets just say the number is 'x'
5/2 + 6x = 7/2 - 7x
6x + 7x = 7/2 - 5/2
13x = 2/2
13x = 1
x = 1/13
proving it
5/2 + 6 × 1/13 = 7/2 - 7 × 1/13
5/2 + 6/13 = 7/2 - 7/13, solving the fraction by finding the L.C.M will result in
77/26 = 77/26
Answer:
1 1/3 chapters per hour
Step-by-step explanation:
eplaination is in the picture
<span>(-2/3)*(w-(4/9)) = -4/3 // + -4/3
(-2/3)*(w-(4/9))-(-4/3) = 0
(-2/3)*(w-4/9)+4/3 = 0
4/3-2/3*(w-4/9) = 0
(-2/3*3*(w-4/9))/3+4/3 = 0
4-2/3*3*(w-4/9) = 0
44/9-2*w = 0
(44/9-2*w)/3 = 0
(44/9-2*w)/3 = 0 // * 3
44/9-2*w = 0
44/9-2*w = 0 // - 44/9
-2*w = -44/9 // : -2
w = -44/9/(-2)
w = 22/9
w = 22/9</span>
