Answer:
Width of rectangular piece = x = 8 inches
Step-by-step explanation:
Perimeter of rectangular piece = 62 inches
Let width of rectangular piece= x
and length of rectangular piece = x+15
We need to find width i.e value of x
The formula used for perimeter of rectangle is: [tex]Perimeter=2(Length+Width)\\[/tex]
Putting values in formula and finding Width:
[tex]Perimeter=2(Length+Width)\\\\62=2(x+x+15)\\62=2(2x+15)\\62=4x+30\\62-30=4x\\4x=32\\x=\frac{32}{4}\\x=8[/tex]
After solving we get value of x = 8
So, Width of rectangular piece = x = 8 inches
what is the answer or solution-15-3p=6
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

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

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?
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 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.
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.
A number added to 12 and then subtracted by 18 equals 26. what is the number?
Answer:
it would be 32. you would take your 26 and add 18 then subtract the 12.
Step-by-step explanation:
hope this helps
Answer:
32
Step-by-step explanation:
x+12-18=26
Subtract the numbers 12 and 18
x-6=26
Add 6 to both sides of the equation
x-6+6=26+6
Simplify- Add the numbers thus getting x=32
The 17th term of an Arithmetic sequence is 51. If the commons difference is 7, what is the first term ?
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]Someone help plsss *giving BRAINLIEST*
