So find factors of 5
1 and 5
both factors must be both negative or both positive to be positive 5
adds to negative 4
to do that, they both must be negative
-5 times -1=5
-5+-1=-6
doesn't work
the only way it would work is if it is what multipies to -5 and adds to -4 which then the numbers would be -5 and 1
Answer:
There doesn't seem to be numbers to answer that, do you have the question right? If it was a difference of 18, for example, the numbers would be 64 and 36.
Step-by-step explanation:
Find 2 numbers that added together, equal 10.
91
82
73
64
55
46
37
28
19
Then subtract them by their opposites. Find the numbers with the difference of 12.
91 - 19 = 72
82 - 28 = 54
73 - 37 = 36
64 - 46 = 18
55 - 55 = 0
46 - 64 = -18
37 - 73 = -36
28 - 82 = -54
19 - 91 = -72
There is no numbers with the difference of 12.
If it was a difference of 18, for example, the numbers would be 64 and 36.
Answer:
X = 15
Step-by-step explanation:
We move all terms to the left:
<em>x+8+2x-(2x+13)=0</em>
We add all the numbers together, and all the variables:
<em>3x-(2x+13)+8=0</em>
We get rid of parentheses:
<em>3x-2x-13+8=0</em>
We add all the numbers together, and all the variables:
<em>x-5=0</em>
We move all terms containing x to the left, all other terms to the right:
<em>x=5</em>
Answer:
y=5x+2
Step-by-step explanation:
Slope formula:
y=mx+b
- m stands for slope
- b stands for y intercept.
Plug the information in:
y=5x+2
Answer:
Patricia is 47 years old
Sharla is 55 years old
Step-by-step explanation:
Rewrite the first sentence as an equation: (S= Sharla) (P= Patricia)
S=P+8
Rewrite the second sentence as an equation:
S+P=102
1) Substitute P+8 as Sharla in the second equation:
P+8+P=102
2) Combine alike terms:
2P+8=102
3) Subtract 8 from both sides:
2P=94
4) Divide both sides by 2:
P=47
5) Substitute 47 as P in the <u>First</u> equation:
S=47+8
6) Solve:
S=55
