Do 560 * .38 which is 212.8 or B, it could be C if you are rounding but 212.8 is the exact answer
the rate of change is -2 for every set shown in the chart on the right
so 6 to 7 would be -11 -2 = -13
7 to 8 would be -13-2 = -15
8 to 9 = -15-2 = -17
B is the answer
So all the angles on one side should equal 180.
50+55= 105
180-105=75
12x+3=75
12x=72
12*6=72
x=6
Answer:
1. D
2. x=65
Step-by-step explanation:
Hi!
Your answer is D because 78 is 120% of x
120% in decimal point is 1.2.
So it's 1.2x is the same as 120% of x
For question 8:
1.2x=78
Isolate x by divide 1.2 on both sides
78/1.2=65
Step-by-step explanation:
Mean=sum of observations/no. of observations
