−15 = 5(3q − 10) − 5q
Answers
Answer:
q = 3.5
Step-by-step explanation:
-15 = 5(3q - 10) - 5q
-15 = (5*3q + 5*-10) - 5q
-15 = 15q - 50 - 5q
-15 + 50 = 15q - 5q
35 = 10q
q = 35/10
q = 3.5
Check:
-15 = 5(3*3.5 - 10) - 5*3.5
-15 = 5(10.5 - 10) - 17.5
-15 = 5*0.5 - 17.5
-15 = 2.5 - 17.5

Xian and his cousin Kai both collect stamps. Xian has 52 stamps, and Kai has 72 stamps. The boys recently
joined different stamp-collecting clubs. Xian's club will send him 12 new stamps per month. Kai's club will
send him 8 new stamps per month. After how many months will Xian and Kai have the same number of
stamps? How many stamps will each have?
After
months Xian and his cousin will have
stamps each.
Answers
Answer:
Step-by-step explanation:
Let the x be the number of months.
In x months, xian will have:
(52+16x) stamps
and kai will have:
(76+12x)stamps
To find out how many months they will have the same number of stamps, we evaluate the two expressions:
52+16x=76+12x
52+4x=76
4x=24
x=6
So xian and kai will have the same number of stamps after 6 months.
Using either of two expressions, each will have:
52+16(6)=76+12(6)= 148 stamps.

65 -3x
The value of the second card starts at $55 and decreases by $2.50 for each of x periods. Its value is ...
55 -2.5x
The equation that can be used to find x that makes the values equal is ...
65 -3x = 55 -2.5x
__
The solution can be found by adding 3x-55 to both sides of this equation.
10 = 0.5x
Multiplying by 2 gives ...
20 = x
After 20 30-day periods. the cards will have the same value.

A fence for a rectangular garden with one side against an existing wall is constructed by using 60 feet of fencing. What is the maximum area that can be enclosed
Answers
Step-by-step explanation:
A fence for a rectangular garden with one side against an existing wall is constructed by using 60 feet of fencing.
Perimeter of rectangle (3 sides)= 60 feet
Let 'x' be the width of the wall
[tex]Perimeter = 2(length)+2(width)\\60=2(length)+2x\\\\60-2x=2(length)\\\frac{60-2x}{2} =length\\Length =30-x[/tex]
Formula for the area of the rectangle is
[tex]Area=length \cdot width\\A=length(x)[/tex]
Replace the length we got using perimeter
[tex]A=(30-x)(x)\\A(x)= 30x-x^2[/tex]
To find out the maximum are we take derivative
[tex]A'(x)= 30-2x\\0=30-2x\\-30=-2x\\x=15[/tex]
find out second derivative to check whether x=15 is maximum
[tex]A''(x)=-2[/tex]
second derivative is negative
So, Maximum area at x=15
To find maximum area we plug in 15 for x in A(x)
[tex]A(x)=30x-x^2\\A(15)=30(15)-15^2\\A(15)=225[/tex]
So, maximum area is 225 square feet

Answer:
Addition
Step-by-step explanation:
You should add 4 and 5 first because of PEMDAS.
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
Since 4+5 is in parentheses it should be done first.
Answer:
Addition
Step-by-step explanation:
This the answer because:
1) First, we have to know the Order of Operations
2) An easy way of remembering this is PEMDAS or GEMS
PEMDAS : Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction
GEMS : Grouping (Parenthesis), Exponents, Multiplication and Division (whichever one comes first from left to right), Addition and Subtraction (whichever one comes first from left to right)
3) In this expression, parenthesis would be first because that's what comes first in the order of operations
4) Inside the parenthesis is another expression where you need to add. Therefore, the answer is addition
