Josh is going to the store with $60 to buy candy. bags of candy corn cost $3 & bags of chocolate cost $5 he needs to buy at least 20 bags of candy.
What do I put for the blank space? 3x+5y_60
Answer:
3a+5b
Step-by-step explanation:
Variable 1: a = candy corn
Variable 2: b = chocolate
Inequality 1: 60 ≥ 3a + 5b
Inequality 2: 20 ≤ 3a + 5b
The inequalities are as such because Josh needs to spend no greater than $60. He must also buy at least 20 bags of candy. The candy corn costs $3, while the chocolate costs $5. An expression for the total cost of the candy would be 3a + 5b.
A plumber charges $75 for the service call and $25 per hour (h) for repairs. Write an algebraic expression to represent the total bill for all plumbing services.
A.
(75 + 25)h
B.
75 + 25h
C.
75h + 25
D.
75 + 25 + h
Answer:B i think if wrong im so sorry
Step-by-step explanation:
Answer:
B 75+25h
Step-by-step explanation:
$75 is the first charge for the service and is constant. $25(per hour) is not constant and changes as the time (hours) changes. That's why it has a h next to it, the h is the variable to hold the place for the hours that would be multiplied in the problem.

Answer: True for all x
Step-by-step explanation:
4x - 6 + 2x = 3(2x-2)
Group Like Terms: 4x+2x - 6 = 3(2x-2)
Add Similar Elements (4x+2x=6x): 6x - 6 = 3(2x-2)
Expand: 3(2x-2) ; 6x - 6
6x - 6 = 6x - 6
Add 6 to Both Sides: 6x - 6 + 6 = 6x - 6 + 6t: 6x - 6x = 6x - 6x
Simplify: 6x = 6x
Subtract: 6x - 6x
Simplify: 0 = 0
Both sides are equal in this equation, therefore all values for x is true.

Answer:
x = 6
Step-by-step explanation:
3x + 4 = 22
subtract 4
3x = 18
divide by 3
x = 6
Answer:
x=6
Step-by-step explanation:
Subtract 4 from each side of the equation to get 3x=18. divide 18 by 3 to get 6, and divide 3x by 3 to get x. x=6

A circle has a circumference of 6. It has an arc of length 1.
What is the central angle of the arc, in degrees?
Answer:
60 degrees
Step-by-step explanation:
s = r (theta)
(theta) = s/r
= 1 / (3/π) = π/3
as a degree π/3 x 180/π = 60
60 degrees
*Circumference = 2πr
6 = 2πr
r = 6/2π = 3/π

S. The area of a stage for a concert is 216 square feet. The length is 6 times the width. Find the dimensions of
the stage
Answer:
Width=6 Length=36
Step-by-step explanation:
The stage is rectangular since the length is not equal to width.
We use the formula (Width × Length) to obtain the area of any rectangle.
But the Length is 6 times the Width, therefore we equate the formula for the area of stage as
Width × 6Width = 216
we get Width as 6 and 6width which is the length as 36

Jacob is ordering baseball gloves for 214 league members. If the gloves are packed in boxes of 8, what is the least number of boxes Jacob needs to order?
Answer:
26.75 so 27
Step-by-step explanation:
214 divided by 8 = 26.75
Answer:
27 boxes
Step-by-step explanation:
214 ÷ 8 = 26.75
Because you can't get .75 of a box, Jacob needs at least 27 boxes.

r1 represents first root, r2 represetnts second root
What are the roots?
Remember, x-r1 = 0 and x-r2=0
Answer:
f(x) = (x - 3)(x - 4)
Step-by-step explanation:
f(x)= x^2 - 7x +12 factors immediately into f(x) = (x - 3)(x - 4).
The roots are {3, 4}

what is 2.1 times 3.2 find the missing partial products HELP.
Given:
The area model for [tex]2.1\times 3.2[/tex].
To find:
The value of [tex]2.1\times 3.2[/tex] and the missing values in the area model.
Solution:
2.1 can be written as 2 and 0.1 on the left side of the area model.
3.2 can be written as 3 and 0.2 on the top of area model.
Area of the four parts of the area model are:
[tex]2\times 3=6[/tex]
[tex]2\times 0.2=0.4[/tex]
[tex]0.1\times 3=0.3[/tex]
[tex]0.1\times 0.2=0.02[/tex]
The complete area model is shown below.
After adding all areas of the area model, we get
[tex]6+0.4+0.3+0.02=6.72[/tex]
Therefore, the value of [tex]2.1\times 3.2[/tex] is 6.72 and the missing values of the area model are 0.3 and 0.02 respectively.
The art club is designing a rectangular mural for the school hallway. Three corners are located at (-1, -1), (-1, 1), and (4, 1) on teh coordinate plane. What would be the forth vertex on the coordinate plane below?
Answer:
The fourth vertex must be located at [tex]Z(x,y) = (4, -1)[/tex]. The graph of the figure is included below.
Step-by-step explanation:
Let be [tex]X(x,y)[/tex], [tex]Y(x,y)[/tex], [tex]Z(x,y)[/tex] and [tex]W(x,y)[/tex] so that a rectangle is formed. Hence, we must satisfy the following conditions:
[tex]X(x,y) = (a, c)[/tex] (1)
[tex]Y(x,y) = (a, d)[/tex] (2)
[tex]Z(x,y) = (b, c)[/tex] (3)
[tex]W(x,y) = (b, d)[/tex] (4)
[tex]a < b[/tex] (5)
[tex]c < d[/tex] (6)
If we know that [tex]a = -1[/tex], [tex]b = 4[/tex], [tex]c = -1[/tex], [tex]d = 1[/tex], then we have the following points:
[tex]X(x,y) = (-1, -1)[/tex]
[tex]Y(x,y) = (-1, 1)[/tex]
[tex]Z(x,y) = (4, -1)[/tex]
[tex]W(x,y) = (4,1)[/tex]
Then, the fourth vertex must be located at [tex]Z(x,y) = (4, -1)[/tex].
