what is the answer or solution-15-3p=6
Answers
Answer:
P = - 7
Step-by-step explanation:
To solve we must put all the literals (letters) on one side of the operation and all the free numbers on the other. To do this we are going to do the same operations on both sides of the equal sign
- 15 - 3p = 6
So, we are going to add 15 on both sides
- 15 - 3p + 15 = 6 + 15
- 3p = 21
We are goint to divide everything by -3
-3p/-3 = 21/-3
It result:
p = -7We check as follows:
We are going to replace the unknown (p) by the value we gave it already (-7)
-15 - 3(-7) = 6
-3 × -7 = +21
-15 + 21 = 6
6 = 6
we have the correct result

A meat distributor paid $2.75 per pound for hamburger and $4.50 per pound for ground sirloin. How many pounds of each did he use to make 75 pounds of meat mixture that will cost $3.24 per pound?
Answers
Answer:
The number of pounds of hamburger meat = x = 54 pounds.
The number of pounds of ground sirloin = y = 21 pounds
Step-by-step explanation:
Let the number of pounds of hamburger meat = x
the number of pounds of ground sirloin = y
How many pounds of each did he use to make 75 pounds of meat mixture that will cost $3.24 per pound?
x + y = 75...... Equation 1
x = 75 - y
A meat distributor paid $2.75 per pound for hamburger and $4.50 per pound for ground sirloin.
$2.75 × x + $4.50 × y = 75 × $3.24
2.75x + 4.50y = 243
We substitute 75 - y for x
Hence,
2.75(75 - y) + 4.5y = 243
206.25 - 2.75y + 4.5 y = 243
Collect like terms
- 2.75y + 4.5 y = 243 - 206.25
1.75y = 36.75
y = 36.75/1.75
y = 21 pounds
Note
x = 75 - y
x = 75 - 21
x = 54 pounds
Therefore:
The number of pounds of hamburger meat = x = 54 pounds.
The number of pounds of ground sirloin = y = 21 pounds

The 17th term of an Arithmetic sequence is 51. If the commons difference is 7, what is the first term ?
Answers
Answer:
The first term is:
[tex]a_1=-61[/tex]Step-by-step explanation:
The arithmetic sequence is defined by
[tex]a_n=a_1+\left(n-1\right)d[/tex]
where
[tex]a_1[/tex] is the first term
[tex]d[/tex] is the common difference
as
the 17th term of an arithmetic sequence is 51.
i.e. [tex]a_{17}=51[/tex]
so
[tex]a_n=a_1+\left(n-1\right)d[/tex]
[tex]a_{17}=a_1+\left(17-1\right)d[/tex]
[tex]51=a_1+\left(17-1\right)7[/tex] ∵ [tex]n = 17[/tex], [tex]a_{17}=51[/tex] , [tex]d=7[/tex]
[tex]a_1+112=51[/tex] ∵ [tex]\left(17-1\right)\cdot \:\:7=112[/tex]
[tex]a_1=-61[/tex]
Therefore, the first term is:
[tex]a_1=-61[/tex]I know it isn’t congruent but how do I explain the reasoning? help ?

The Key Club is having a fundraising dinner for charity. The venue that holds a maximum of 500 people will
cost $1000 and it costs $20 per person for the food. The two charity representatives get to attend for free.
Write an inequality and then determine how many people must come to keep costs at most $25 per person.
Answers
Answer:
[tex]\dfrac{\$1000+\$20x}{x} \leq \$25[/tex]
Minimum 200 people other than the 2 charity representatives.
Step-by-step explanation:
Given that:
The venue can hold a maximum of 500 people.
Cost of venue = $1000
Per person cost for food = $20
Two charity representatives get to attend the dinner for free.
To find:
The inequality and to determine how many people must come to keep costs at most $25.
Solution:
Let the number of people attending the dinner = [tex]x[/tex]
Cost of food for [tex]x[/tex] people = [tex]\$20x[/tex]
Total cost = $1000 + [tex]\$20x[/tex]
Cost per person = Total cost divided by Number of people attending the dinner.
As per question statement:
[tex]\dfrac{\$1000+\$20x}{x} \leq \$25\\\Rightarrow 1000+20x\leq25x\\\Rightarrow 1000 \leq 5x\\\Rightarrow x\geq 200[/tex]
Therefore, the answer is:
Minimum 200 people other than the 2 charity representatives should attend the dinner.

Answers
Answer:
x = 43
Step-by-step explanation:
since the line is parallel, there are a few relationships that goes on in between the parallel lines with the angles formed by the third line (the third line is known as a transversal)
the two angles shown are same side interior angles because they are on the same side of the transversal and on the inside of the parallel lines
same side interior angles always add up to 180 since, if you put them together, they would form a straight angle
so we can set the equation to x + 27 + x + 67 = 180
add like terms: 2x + 94 = 180
subtract 94 from 180: 2x = 86
divide both sides by 2: x = 43
