Well to find the value of x you need to get x alone. so you -1 from 3 and do 2/27 and your answer is 0.074
How generous
x+3=8
minus 3 both sides
x+3-3=8-3
x+0=5
x=5
Answer:
x = 5, y = 8, z = -3
Step-by-step explanation:
Opposite sides of a parallelogram are congruent so to find x:
x + 7 = 3x - 3
-2x = -10
x = 5
To find y:
y + 2 = 2y - 6
-y = -8
y = 8
Therefore, z = x - y = 5 - 8 = -3.
Step-by-step explanation:
here
f(x)=2x^2-1
Now
f(4y)=2*4y^2-1
<span><u><em>The correct answer is:</em></u>
$42.
<u><em>Explanation:</em></u>
The best way to find a total bill including tip (or tax if that is what you are looking for - it is found the same way), is to multiply the original total by 1 + the percentage of the tip.
Since the percentage is 20%, we add 0.20 to 1 to get 1.20.
Now we multiply that by the original cost to get the final answer.
1.20*35 = 42</span>
