Step-by-step explanation:
Katie brought a birthday treat to school. She has 40 pieces of candy to share equally with the students in her class. If there are n students in the class, which expression shows how many pieces of candy each student will get?
Answer:
Step-by-step explanation:
Pieces = 40/n
Pieces = the number of pieces each student will get
n = the number of students in the class.
n
n has an upper limit of 40. Each student will get exactly 1 piece of candy
Other values of n could be
1 2 4 8 5 10 20 40
Answer:
2 candie each because if there 20 and 40 candie it well be 2:)`

Step-by-step explanation:
X-4/2 = 4x-9/3
A x=-6
B x=-3/5
C x=6/5
D x =6/11
Answer:
x = 6/5
Step-by-step explanation:
x-4 4x-9
------ = ----------
2 3
Using cross products
3 * (x-4) = 2 ( 4x-9)
Distribute
3x-12 = 8x-18
Subtract 3x from each side
3x-12-3x = 8x-18-3x
-12 = 5x-18
Add 18 to each side
-12+18 =5x-18+18
6 = 5x
Divide by 5
6/5 = 5x/5
6/5 =x
In football, the path that a defender must run to
tackle the ball carrier is called the path of pursuit.
If the ball carrier runs 40 yards to the end zone
and the path of pursuit is 45 yards, how far
apart were the ball carrier and defender when
they started? Answer with appropriate
precision.
Use the distributive property to remove the parentheses. -6(5y-2u-3)
by multiplying each term in the parentheses by the term outside
-6(5y-2u-3) = (-6 × 5y) + (-6 × - 2u) + (-6 × -3)
= -30y + 12u + 18

Need Help?
Read It
If x terminates in the fourth quadrant, then we know that sin(x) < 0 and cos(x) > 0. Given that sec(x) = 8, we immediately have
cos(x) = 1/sec(x) = 1/8
Recall the Pythagorean identity,
cos²(x) + sin²(x) = 1
Then it follows that
sin(x) = -√(1 - cos²(x)) = -3√7/8
Now recall the double angle identities,
sin(2x) = 2 sin(x) cos(x)
cos(2x) = cos²(x) - sin²(x)
Then
sin(2x) = 2 (-3√7/8) (1/8) = -6√7/64 = -3√7/32
cos(2x) = (1/8)² - (-3√7/8)² = -62/64 = -31/32
By definition of tangent,
tan(x) = sin(x)/cos(x)
Then
tan(2x) = sin(2x)/cos(2x) = (=3√7/32) / (-31/32) = 3√7/31

Answer:
[tex]=\frac{3x}{20}[/tex]
Step-by-step explanation:
[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \:a\cdot \frac{b}{c}\cdot \frac{d}{e}=\frac{a\:\cdot \:b\:\cdot \:d}{c\:\cdot \:e}[/tex]
[tex]=\frac{3x\cdot \:2}{8\cdot \:5}[/tex]
[tex]=\frac{3x}{4\cdot \:5}[/tex]
[tex]\mathrm{Multiply\:the\:numbers:}\:4\cdot \:5=20[/tex]
[tex]=\frac{3x}{20}[/tex]
Answer:
Do you mean 3/8 times 2/5? It equals 3/20
Step-by-step explanation:
So multiple the top numbers together for the top result and multiple bottom numbers for bottom result. 3 times 2 equal 6, 8 times 5 equal 40. the result is 6 over 40. After simplifying, we have 3 over 20 (dividing both 6 and 40 by 2)

Answer:
h(-2) = 32
[tex]\displaystyle\mathsf{h(\frac{20}{7})=-2}[/tex]
Step-by-step explanation:
Given the linear function, h(x) = -7x + 18:
h(-2)In order to evaluate h(-2), simply substitute the value of the given input, x = -2, into the function.
h(x) = -7x + 18
h(-2) = -7(-2) + 18
h(-2) = 14 + 18
h(-2) = 32
Therefore, the output value when x = -2 is: h(-2) = 32.
Find x if h(x) = -2.
This particular problem asks us to find the corresponding domain (x-value) given the range value of y = -2.
Substitute the value of y = -2 into the function to solve for the value of x:
h(x) = -7x + 18
-2 = -7x + 18
Subtract 18 from both sides:
-2 - 18 = -7x + 18 - 18
-20 = -7x
Divide both sides by -7 to solve for x:
[tex]\displaystyle\mathsf{\frac{-20}{-7}\:=\:\frac{-7x}{-7} }[/tex]
[tex]\displaystyle\mathsf{x\:=\frac{20}{7}}[/tex]
Therefore, the value of x when h(x) = -2 is: [tex]\displaystyle\mathsf{h(\frac{20}{7})=-2}[/tex].

Answer:
1/5
Step-by-step explanation:
it appears as those two distinct points on the graph are (-3,1) and (2,2)
so take the difference of the y-values and put it over the difference of the x-values to get a fraction to represent the slope
2-1 / 2-(-3) = 1/5
if you start from the point (-3,1) you must rise by one unit and then run five units to the right to get to (2,2)

Step-by-step explanation:
how do you find the vertex of a quadratic equation in standard form?
Answer:
Step-by-step explanation:
The standard form of a quadratic equation is ax² + bx + c, where a ≠ 0.
Given that the axis of symmetry occurs at x = h, then we can assume that the h coordinate of the vertex is the same as the x-coordinate in an ordered pair, (x, y).
In order to find the vertex, (h, k), use the following formula to solve for the value of h:
[tex]h = \frac{-b}{2a}[/tex].
Example:To demonstrate this concept, let's say that we're given the following quadratic equation: 2x² + 8x + 8, where a = 2, b = 8, and c = 8. Substitute the values of a and b into the given equation for solving the x-coordinate (h) of the vertex:
[tex]h = \frac{-b}{2a}[/tex]
[tex]h = \frac{-8}{2(2)} = \frac{-8}{4} = -2[/tex]
Therefore, h = -2.
Next, substitute the value of h = -2 into the given quadratic equation in order to solve for its corresponding y-coordinate (k ) of the vertex:
k = 2x² + 8x + 8
where: a = 2, b = 8, and c = 8
k = 2(-2)² + 8(-2) + 8
k = 2(4) - 16 + 8
k = 8 - 16 + 8
k = 0
Therefore, the vertex of the quadratic equation, 2x² + 8x + 8 is (-2, 0).

Mrs. Womack wants to make 22 mini pizzas for her favorite math class party. She
has 18 cups of flour and each mini pizza takes 4 cup of flour. Does she have enough
flour? If not, how much more flour does she need? If so, how much flour will she
have left over?
Answer:
She can only make 4 whole mini pizzas and needs 70 more cups of flour and will not have any leftover after that.
Step-by-step explanation:
18/4= 4.5
22*4=88
88-18= 70
Answer:
No
Step-by-step explanation:
Mrs. Womack need 22 mini pizzas and each requires 4 cups and when you do the math 22 times 4 is 88, and she only has 18 cups so she would only have enough to make 4 full pizzas. So in total she needs 88 cups meaning she needs 70 more.
22x4=88
88-18=70
18÷4= 4.5
Answer:70 more cups are needed
Kim's school is selling tickets to a play. On the first day of ticket sales the school sold 5 senior citizen tickets and 6 child tickets for a total of $148. The school took in $189 on the second day by selling 7 senior citizen tickets and 7 child tickets. Find the price of a senior citizen ticket andthe price of a child ticket.
Answer:
Child $13 and Adult $14
Step-by-Step
x=cost of child tix
y=cost of adult tix
first day: 5y+6x=148
2nd day: 7y+7x=189
series of equations so solve for one variable
7y=189-7x
y=27-x
then plug into other equation
5(27-x)+6x=148
135-5x+6x=148
x=148-135
x=13
then plug into y equation
y=27-13
y=14
