Well if your sum is -18 then you know your answers are going to be negative numbers.
<span>make x be your first unknown negative even integer. you want your negative x and then negative x minus two and negative x minus four </span>
<span>x1= x </span>
<span>x2= x-2 </span>
<span>x3= x-4 </span>
<span>you know all three need to equal -18 </span>
<span>solve for x: </span>
<span>-18= -x + (-x-2) + (-x-4) </span>
<span>-18 = -x-x-2-x-4 </span>
<span>-18+2+4= -3x </span>
<span>12=-3x </span>
<span>12/-3=x </span>
<span>-4=x </span>
<span>then plus x into the first problem. </span>
<span>x1= -4 = -4 </span>
<span>x2= -4-2 = -6 </span>
<span>x3= -4-4 = -8 </span>
<span>so your integers would be -4, -6, and -8 </span>
<span>check: </span>
<span>(-4) + (-6) + (-8) = -18 </span>
<span>let me know if you have any questions. </span>
Answer:
The answer is 1
Step-by-step explanation:
1² = 1×1

Answer:
There are 80 men on the train.
Step-by-step explanation:
M : W
4 : 5
W : C
10 : 9
As you can see, the units for women is not equal, so I shall multiply the first ratio by 2 so that the units for women is 10.
M : W
8 : 10
Now that everything has the same units, I can put the ratio of men, women and children together:
M : W : C
8 : 10 : 9
Total number of units = 8 + 10 + 9
= 27
27 units = 270
No. of men (8 units) = × 270
= 80
