Answer:
5/4 kg is Parcel A
im guessing what you meant was that parcel B is 3 times as heavy as A.
Step-by-step explanation:
Lets say parcel A is x
3x would be parcel b
x + 3x = 5 kg
4x = 5 kg
x = 5/4 kg
Answer:
Correct answer: x₁ = 1 / √3 = √3 / 3 or x₂ = - 1 / √3 = - √3 / 3
Step-by-step explanation:
Given:
3 x⁴ + 14 x² - 5 = 0 biquadratic equation
this equation is solved by a shift x² = t and get:
3 t² + 14 t - 5 = 0
t₁₂ = (-14 ± √14² - 4 · 3 · 5) / 2 · 3 = (-14 ± √196 + 60) / 6
t₁₂ = (-14 ± √256) / 6 = (-14 ± 16) / 6
t₁ = -5 or t₂ = 1 / 3
the solution t₁ = -5 is not accepted because it cannot be x² = -5
we accepted t₂ = 1 / 3
x² = 1 / 3 ⇒
x₁ = 1 / √3 = √3 / 3 or x₂ = - 1 / √3 = - √3 / 3
God is with you!!!
Answer:
X = 10.4
Step-by-step explanation:
Since the angle is a 90 degress angle we can assume that
39 + (5x-1) = 90 degrees.
Therefore we can subtract 39 from both sides which will give us
5x-1=51
Add 1 to both sides
5x = 52
Divide both sides by 5
x=52/5
The answer is
X = 10.4
Hope this helps! :)
Answer:
-2w+-14
3d+3
-7y+-16
Step-by-step explanation:
Remove ()- <u>2w</u>+-9+<u>-4w</u>+-5
2w+-4w = -2w
-9+-5 = -14
-2w+-14
Remove ()- <u>6d</u>+5+-2+<u>-3d</u>
6d+-3d = 3d
5+-2 = 3
3d+3
Remove ()- 4+<u>-5y</u>+<u>-2y</u>+-16
-5y+-2y = -7y
4+-16 = -12
-7y+-12
