X is -8
To solve the problem you have to get X by itself. So you would multiply every number in the equation by 4. Which will give you -X + 12 = 20
Now you have to subtract 12 on both sides of the equal side giving you -X = 8 since the positive twelve cancels out.
Finally you divide by negative 1 since X can NOT be a negative!
Your final answer should be X = -8
I hope that helped and you know what to do now...
Answer:
4 is approx 5.7 feet
Step-by-step explanation:
let 'x' = length of leg
use pythagorean theorem to get:
x² + x² = 8²
2x² = 64
x² = 32
x = = · ·
x = 4
Answer: X=-3
Step-by-step explanation:
-4(-2x+5)-5x+5=-24 (=) [(-4×-2x)+(-4×5)]-5x+5=-24 (=) [(8x)+(-20)]-5x+5=-24 (=) 8x-20-5x+5=-24 (=) 3x-15=-24 (=) 3x=-9 (=) x=-9/3 (=) x=-3
Answer:
The equation is y= 0.08 x+55
Step-by-step explanation:
Let's use total cost y= Variable cost + fixed cost.
Here fixed cost =$55
And variable cost for each minute =0.08
That's variable cost for x minutes =0.08
So, total cost y=0.08 x+55
