A kilogram is equal to 1,000 grams, if you multiply it by 8, you get 8,000 grams, then you add 622 grams. You're finally left with 8,622 grams.
We don't know the number she started with, so let's call it x.
<span>Petra started with a number added 3: x + 3
</span>
<span>multiplied the result by 4: 4(x + 3)
</span><span>subtracted 6: 4(x + 3) - 6
</span>
<span>and multiplied that result by 3: 3[4(x + 3) - 6]
</span>
her final answer was 90: <span>3[4(x + 3) - 6] = 90
Now we solve the equation for x.
</span><span>3[4(x + 3) - 6] = 90
</span>
<span>4(x + 3) - 6 = 30
4(x + 3) = 36
x + 3 = 9
x = 6
The number is 6.

Answer:
The answer to your question is letter A
Step-by-step explanation:
Data
Vertex = (-5, -2)
Point = (-4, 2)
This is a vertical parabola the opens upwards.
The equation is
(x - h)² = 4p(y - k)
Substitution
(-4 + 5)² = 4p (2 + 2)
Simplification
1² = 4p(4)
1 = 16p
p = 1/16
Equation of the parabola
(x + 5)² = 4/16(y + 2)
x² + 10x + 25 = 1/4y + 1/2
Conclusion
The coefficient of the squared expression is 1
Answer:
∠ABC=90°
Step-by-step explanation:
if ∠DAB =110 then ∠BAC =180-110 =70° because straighht lines make 180°∠s
use the fact that the sum of angles in a Δ is 180°
∠ABC= 180-20-70= 90
Answer:
(3) is the right answer because 360° - 308° = 52°
