Help me with number 4 plzzzzzz
Answer: x=8
Step-by-step explanation:
To solve for x, we want to use our algebraic properties to isolate x.
[tex]-\frac{1}{2}x-7=-11[/tex] [add both sides by 7]
[tex]-\frac{1}{2}x=-4[/tex] [multiply both sides by -2]
[tex]x=8[/tex]
Now, we know that x=8.
A volcanic eruption releasing rock, ash, and dust particles into the air is an example of which interaction?
the biosphere interacting with the geosphere
the geosphere interacting with the atmosphere
the geosphere interacting with the hydrosphere
the hydrosphere interacting with the atmosphere
The interaction described is that of the geosphere interacting with the atmosphere.
The geosphere refers to all the rock and mineral materials that we have on our planet including:
Lava in the mantle Soil Mountains and everything made of rockThe atmosphere is the air that surrounds the Earth including gases like Nitrogen and Oxygen.
When a volcano erupts therefore, it is releasing rock (geosphere) into the air (atmosphere).
As a result, we can conclude that a volcano erupting is an interaction between the geosphere and the atmosphere.

Alonso brings \$21$21dollar sign, 21 to the market to buy eggs and avocados. He gets eggs that cost \$2.50$2.50dollar sign, 2, point, 50. Then, he notices that the store only sells avocados in bags of 333 for \$5$5dollar sign, 5. He wants to buy as many avocados as he can with his remaining money. Let BBB represent the number of bags of avocados that Alonso buys. 1) Which inequality describes this scenario?
This scenario is described by the following inequality:
[tex]2.5 + 5B \leq 21[/tex]
-------------------------
First, we find Alonso's total spendings.He spends $2.50 in eggs.After that, he buys B bags of avocados, each costing $5, and thus, his spending on avocados is: [tex]5B[/tex]His total spending is given by:[tex]T = 2.5 + 5B[/tex]
-------------------------
He brought $21 to the market, thus, his total spending can be at most $21, that is:[tex]T \leq 21[/tex]
Replacing the equation for T, the inequality is:
[tex]2.5 + 5B \leq 21[/tex]
