x=25 failled in both
Step-by-step explanation:
1) 4(x+7)=80
Value of x
Multiply
4x+28=80

Answer:
B. 110.5 square units
Step-by-step explanation:
The area of a rhombus is half the product of the diagonals.

Ratio of number of classes and the time taken to conduct each one of them on Thursday = 6 : 8
Ratio of number of classes and the time taken to conduct each one of them on Friday = c : 4
Which means :-
6 : 8 :: c : 4
6/8 = c/4
= 6 × 4 = c × 8
= 24 = 3 × 8
c = 3
The ratio = 6 : 8 :: 3 : 4
Which means that C = 3 .
