<span>2x − 3y − z
</span><span> x = −2,
</span><span> y = 3,
</span><span> z = −2
What we must do is replace the values given in the equation. We have then replacing:
</span> 2*(-2) - 3*(3) - (-2) = -11
The answer is -11
Answer:
Total paintings Sergio have in his art collection after his donation = p - 4
Step-by-step explanation:
P.S - The exact question is -
Given -Sergio has p paintings in his art collection. He and other local painting collectors agreed to donate a total of 48 paintings to the local museum. Each of the 12 collectors will donate the same number of paintings.
To find - How many paintings will Sergio have in his art collection after his donation ?
Proof -
Given that,
Total collectors = 12
Total painting that has to denote = 48
⇒12 collectors donate paintings = 48
⇒1 collector donate painting =
= 4 paintings
∴ we get
Each collector donate paintings = 4
⇒Sergio donate total paintings = 4
Now,
Total pictures Sergio have = p
After donating,
Total left paintings = p - 4
∴ we get
Total paintings Sergio have in his art collection after his donation = p - 4
Because of the Vertical Angles theorem, we know that the two expressions are equal.
6x - 35 = 4x + 11
Add 35 to both sides: 6x = 4x + 46
Subtract 4x from both sides: 2x = 46
Divide by 2 on both sides: x = 23
Now, insert x into one of the equations: 6(23) - 35
138 + 35
103
103 + K = 180
Subtract 103 from both sides: K = 77
K = 77
