Answer:
7x-1
Step-by-step explanation:
14 + 7x - 15 = k
7x - 1 = k
Finding x,
14 + 7x - 15 = k
=> 14 + 7x = k + 15
=> 7x = k + 15 - 14
=> x = (k + 1)/7
So, 7 * (k+1)/7 - 1 = k
k + 1 - 1 = k
=> k = k
So the answer is true that 7x - 1
Answer:
-9
Step-by-step explanation:
The missing number will be labeled as x.
-15*x*8*(-4)=-4320
480x=-4320
x=-9

Answer:
25
Step-by-step explanation:
use pythagoras theorem:
sqrt of: a^2+b^2 = c
where
a=24
b=7
c=x
so substitute these values in the theorem:
sqrt: 24^2+7^2=25
hope this helps!
