3.given the formula D=ABC, WHAT IS THE FORMULA FOR C
a.c=ab divided by d
b.c=ad divided by c
c. c= d divided by ab
d. c=abd

Answer 1

(1) we have been asked to find the value of y in this equation 16y=164.

The given equation can be solved as below

`16y=164.\\ \\ \text{Divide both the sides of 16 we get}\\ \\ y=10.25=10 (1)/(4) \\`

Hence the correct option is a

2.Find the value of Z in the following equation 8Z=64

we are given that

`8Z=64\\ \\ \text{Divide both the sides by 8 we get}\\ \\ z=8`

Hence the correct option is a

3.given the formula D=ABC,we have been asked to find the formula for C.

we can solve it as below

`D=ABC\\ \\ \text{Divide both the sides by AB we get}\\ \\ (D)/(AB)=C\\ \\ C= (D)/(AB)\\`

Hence the correct option is C.

Answer 2

1). 16 Y= 164. ( then divided)
Y= 164 : 16
Y= 41 : 4
Y = 10 +1/4

2) 8z = 64. (then divided)
z= 64 :8
z= 8


3. D = A•B•C. ( divided)
D : A•B = C

C= D:AB

c. c= d divided by ab
