Answer:
Step-by-step explanation:
7x + 8y + 5z
I put the equations in parentheses, assuming that I would be adding both of the equations together. Then, I removed them and combined the like terms. I used two calculators to check my answer, and this should be correct.
To add these to expressions we have to combine like terms:
(4x + 3x) + (3y + 5y) + (2z + 3z) = 7x + 8y + 5z
<em>Like terms - In algebra, like terms are terms that have the same variables and powers</em>.
plz mark me brainliest :)
-0.5
with T = 50⁰C, we have:
50 = 200 - 5x - x²
<=> x² + 5x = 150
<=> x² + 5x - 150 = 0
=> x = 10
