Answer:
5
Step-by-step explanation:
because ?*9=45
45÷9=5
Answer:
A
Step-by-step explanation:
The additive inverse property states that if we have a number a, then:

Here, we have the equation:

And we divide both sides by 2:

To acquire:

So, we did <em>not</em> use the additive inverse property since we didn't add anything.
Instead, we used the<em> division property of equality</em> by dividing both sides by 2.
So, our answer is A.
And we're done!
Answer:
30 is the least common factor or lcm
Step-by-step explanation:
when adding fractions you always have to find the lcm
First let’s find the equation:
a = (42-21)/(26-13)
a= 21/13
y-y1 = a(x-x1)
y-21=(21/13)(x-13)
y-21=(21/13)x - 21
y=(21/13)x-21+21
y=(21/13)x
Now we will find the other point:
X = 2 >> y =(21/13)*2 = 3.23 (not)
X = 3 >> y =(21/13)*3 = 4.84 (not)
X = 4 >> y =(21/13)*4 = 6.46 (not)
X = 5 >> y =(21/13)*5 = 8.07 (yes) find the answer
