It'll be 3/4 lbs I'm pretty sure...
Step-by-step explanation:
marlena steps should look like this:
2x + 5 = -10 - x
(minus 5 from both sides)
2x = -15 - x
(add x to both sides)
3x = -15
(divide by 3)
x = -5
Answer: 21.78
Step-by-step explanation: Multiply 33 by .66. You will get 21.78.
If you multiply the two numbers, you will have 36 + 78i.
*I assumed you had a typo in the first expression, it is generally written as 6 + 3i. If you meant, 6i + 3i, it should have been just 9i.
To find this product, we use the foil method.
(6 + 3i)(10 + 8i)
60 + 48i + 30i + 24i^2
60 + 78i + 24(-1)
34 + 78i
Answer:
x = 21°
Step-by-step explanation:
Complementary angles have a sum of 90°. If ∠A + ∠B = 90°, we know that
x - 6° + 3x = 90°.
4x - 6° = 90°
4x = 96°
x = 24°
Hope this helps!
