Answer:
3
Step-by-step explanation:
To find 12.5% of 2 dozen
We convert 2 dozen into a number which would be:
2×1 dozen (1 dozen = 12)
2×12=24
12.5% of 24 will be
10% of 24 will be 24÷10=2.4
2.5% will be 1/4 of 10%
2.5% = 2.4÷4
2.5%=0.6
12.5%=0.6+2.4
12.5%=3
The answer is a if the line is dotted/dashed. The answer is c if the line isn't dotted/dashed.
Answer:
-27
Step-by-step explanation:
Given expression:
-9(x + 3) = 27
Now use the open the bracket;
-9x - 27 = 27
Given -9x + (?) = 27
Comparing the two equations shows that the question mark corresponds to the value -27;
The solution is -27
33*12=396
396+9=405
3+5+7=15
405/15=27
P= 27*3=81
Q=27*5=135
R=27*7=189
