To find out the answer, let's factor out -42 (as if it's a positive number).
42: 1 x 42, 2 x 21, 3 x 14, 6 x 7.
With these given factors and due to the product being negative, we will go on and off with them being negative to find which sum up to 11.
Let's try 1 and 42.
-1 + 42 = 41
-42 + 1 = -41.
1 x 41 is not our answer.
Let's try 2 and 21.
2 - 21 = -19
-2 + 21 = 19
2 x 21 is not our answer.
Let's try 3 and 14.
-3 + 14 = 11
3 - 14 = -11.
Your answer is:
-3 and 14 sum up to 11 and make a product of -42.
-3 and 14 are your numbers.
I hope this helps!
Answer:
cesar is 11 1/4 years old
Step-by-step explanation:
k = kaleighs age
d = dwaynes age
3k - 2d = 5
d + k = 30
rewrite
-k -k
d = 30 - k
substitute
3k - 2(30 - k) = 5
3k - 60 + k = 5
4k - 60 = 5
+ 60 +60
4k = 65
/4 /4
k = 16.25
16.25 - 5 = 11.25 or 11 1/4
