2e - 3f = 4

Varvara68 [4.7K]

Answer:

The value of e is -1 and f is -2.

Step-by-step explanation:

The steps are :

$2e - 3f = 4 - - - (1)$

$2e - 5f = 8 - - - (2)$

$2e - 3f - 2e - ( - 5f) = 4 - 8$

$2f = - 4$

$f = - 4 \div 2$

$f = - 2$

$substitute \: f = - 2 \: into \: (1)$

$2e - 3( - 2) = 4$

$2e + 6 = 4$

$2e = 4 - 6$

$2e = - 2$

$e = - 2 \div 2$

$e = - 1$

Computer battery A has 4/5 of its power remaining. Computer battery B has 9/20 of its power remaining. How much more power does

zhuklara [117]

Answer:

7/20

Step-by-step explanation:

GIven:

Battery A = 4/5 remaining

Battery B = 9/20 remaining

assuming both batteries are otherwise identical (except for charge level remaining), then,

Battery A - Battery B

= 4/5 - 9/20

we need to convert both fractions to same denominator to perform the subtraction easily. Note that the Least Common Multiple for 5 and 20 is 20, hence we convert both denominators to 20,

Battery A - Battery B

= 4/5 - 9/20

= (4/5) (4/4) - 9/20

= 16/20-9/20

= 7/20
