Step-by-step explanation:

1. -7 = w + 5

w = -12

(-12 + 5 = -7)

2. -4p + 38 = 10

-38 -38

-4p = -28

/-4 /-4

p = 7

3. -3 1/2 = -1 1/4b

Duncan takes a break from studying and goes to the gym to swim laps. If swimming burns 9.05×105 cal per hour, how many kilojoule

fgiga [73]

For this case we have to by definition:

1 kilojoule equals 0.239006 kilocalorie.

1 kilocalorie equals 1000 calories

Then, if we have: $9.05 * 10 ^ 5 \frac {calories} {hour} *\frac {1} {1000} \frac {kilocaloria} {calorie} = 9.05 * 10 ^ 2 \frac {kilocaloria} {hour}$

Now:

$9.05 * 10 ^ 2 \frac {kilocaloria} {hour} * \frac {1} {0.239006} \frac {kilojoule} {kilocaloria} = 3786.52 \frac {kilojoule} {hour}$

Answer:

$3786.52 \frac {kilojoule} {hour}$
