It sounds like initially we have a total of 18*5 = 90. Then we are adding 5 + 4 +3 +2 +1 to this.
so that gives us 105.
105/5 = 21
Are you solving for X? If so, your answer will be x=-3. Hope this helps!
Answer:
a = -7
B= *4
Step-by-step explanation:
Answer is C
3.2 oz + 4.7oz = 7.9 oz * 4 = 31.6oz total
in such cases where 2 line intersect each other, opposite angels are equal
so
2x+2 = 3x - 52
now subtracting 2 from both side
2x +2 -2 = 3x - 52 - 2
2x = 3x - 54
subtracting 3x from both side
2x -3x = 3x -54 - 3x
-x = -54
drividing by -1 both side
-x/-1 = -54/-1
x = 54
