Terms may consist of variables and coefficients, or constants. Like terms are terms that differ only in their numerical coefficients. the factors of 10 are 1, 2 ... Then you choose the biggest factor that can be found in each number.
I hope this helped you but, I did not have your exact answer
Answer:
x = 25
Step-by-step explanation:
2x-20=30
First, isolate the term with x in it by moving everything else to the other side:
2x = 30 + 20
Simplify like terms:
2x = 50
Further isolate the x by dividing by 2 on both sides:
2x/2 = 50/2
The 2 cancels out on the left, leaving:
x = 25
Answer:
6
Step-by-step explanation:
Y is directly proportional to 1/x2
Y = k/x2
Where k is the proportionality constant
y1*(x1)2 = y2*(x2)2
7.2*(10)2 = 20*(x2)2
x2 = sqrt(36)
X = 6
I would go with -15 that’s what I came up with
