The next the sequence is 19,23,27. it increases by 4. John is wrong
Answer:
12
Step-by-step explanation:
4(x-6)=24
4x-24=24
+24 +24
4x=48
x=12
Answer:
See below
Step-by-step explanation:
5x + y = 9 re-arrange to y = 9-5x
use this value of 'y' in the second equation:
10x - 7(9-5x) = - 18
solve for x = 1
sub in this value of 'x' into one of the equations to compute 'y'
5 (1) + y = 9
y = 4
10 mean 100%
x mean 7%
--------------------
x=7*10/100 = 70/100 = 0,7
hope this helped
