Answer:

k = 18

when x = 4, y = 3, z = -24

Step-by-step explanation:

x = k * y * z

Find k when x = 4, y = 3, and z = 24

4 = k * 3 * 24

4 = k * 72

4 = 72k

k = 72/4

k = 18

find z when x = -3 and y = 4

x = k * y * z

-3 = 18 * 4 * z

-3 = 72 * z

-3 = 72z

z = 72/-3

z = -24

Solve for p: 8 = p over 7 please help!!!
frez [133]

Answer: p= 56

8 = p/7

This means to make p by itself, you have to multiple both sides by 7 to cancel out the 7. On the left side, it’d be 8 times 7, which is 56. On the right side, the 7 cancels out and isolates p.

Help my boy please dawg
creativ13 [48]
Answer:
2j-42

Explanation:
The phrase is “42 less than twice Janelle’s age”. Basically, this can be separated into “42 less than” and “twice Janelle’s age”. “Twice Janelle’s age” infers that Janelle’s age is doubled; This can be achieved by 2j because it multiplies Janelle’s age by 2(Times 2 is doubling, times 3 is tripling, and times 4 is quadrupling). The second part is “42 less than” meaning something, in this case Janelle’s age, is subtracted by 42 because less than means negative/minus; This is written as “-42”. So, when we put “42 less than Janelle’s age” together, it becomes -42+2j, which ordered correctly becomes as 2j-42.
