So the whole goal of this is to get the variable (z) all by itself on one side with a coefficient (the number in front of the variable (z)) of one. All you have to do is add seven to each side to get z alone and then divide by two:
2z-7< or equal to 1
+7
2z< or equal to 8
/2
z< or equal to 4
Step-by-step explanation:
Let the 5 even integers be x-4,x-2,x,x+2,x+4
Hence, x-4+x-2+x+x+2+x+4=530
Hence, 5x=530
Hence, x=530/5
Hence,x=106
so.. the integers are 102,104,106,108,110
Answer:
Cube 2
Step-by-step explanation:
The order of operations are PEMDAS.
P = parenthesis
E = exponent
M = multiplication
D = division
A = addition
S = subtraction
Since we don't have any parenthesis, so the first thing we have to do is solve the exponent
