5/8 9/x
Cross multiply
9x8=72
5×x=5x
Rewrite the equation
72 = 5x
Divide by 5
72÷5=14.4
So, x=14.4
Answer:
Set it up using the slope from the two points. (c - (-5))/3 - 1 = slope = (c + 5)/2. Now put this into slope intercept since they give you the y intercept of 7. y = x*(c + 5)/2 + 7. Now put in the point, (1,-5). -5 = 1*(c+5)/2 + 7. Subtract 7 from both sides. Now multiply through and you can solve for c.
Step-by-step explanation:
Answer:
c=4
Will venus1234 delete the c4?
Step-by-step explanation:
You simplify by distributive property
2c+2=10
Then you can use subtraction property of equality to subtract 2 from both sides to get
2c=8
Then do division property of equality to get the unit rate of c.
You end up with
c=4

Answer:
x = ± 
Step-by-step explanation:
Given
3x² - 9 = 0 ( add 9 to both sides )
3x² = 9 ( divide both sides by 3 )
x² = 3 ( take the square root of both sides )
x = ±
