qiulian and tammy have 2400 cards. tammy has twice as many cards as qualian.how many cards must tammy gaive qiulian so that tey have a the same number of card?
Tammy must give Qiulian 800 cards, so that they have the same number of card.
Let Qiulian's card be Q.Let Tammy's card be T.Given the following data:
Total cards, T = 2400 cards.How to solve the word problem.Translating the word problem into an algebraic expression, we have;
Qiulian and Tammy have 2400 cards:
[tex]Q+T=2400[/tex] .....equation 1.
Tammy has twice as many cards as Qiulian:
[tex]T=2Q[/tex] .....equation 2.
To determine the amount of card that Tammy must give Qiulian so that they have the same number of card:
Substituting eqn. 2 into eqn. 1, we have:
[tex]Q+2Q=2400\\\\3Q=2400\\\\Q=\frac{2400}{3}[/tex]
Q = 800 cards.
For Tammy:
[tex]T =2Q\\\\T=2\times 800[/tex]
T = 1600 cards.
Therefore, Tammy must give Qiulian 800 cards, so that they have the same number of card.

Find the values of x, y, and z in the
parallelogram. Note that the figure is not
drawn to scale.
Step-by-step explanation:
we know that sum of all angles of a triangle is 180°
so, angle N + angle O + angle M = 180°
=> (-5b+16)+(-b+8)+(-9b-9) = 180°
=> -5b+16-b+8-9b-9 = 180°
=> -15b+15 = 180°
=> -15b = 180-15
=> -15b = 165
=> b = -165/15
=> b = -11
angle N => -5(-11)+16
=> 55+16 => 71
angle O => -(-11)+8
=> 11+8 => 19
angle M => -9(-11)-9
=> 99-9
=> 90

Answer:
I'm certainly late, but it took me a while to figure this one out so I want to leave an answer.
A=-5 B=2 C=19 D=-2
Step-by-step explanation:
I looked back at the video and actually tried to pay attention and the way to figure these problems out is set up all of the degrees of x in an equation. So, take all of the coefficients that are attached to an x^3, and set them up equal to each other. This makes -5=A, which is the first answer. Repeat for x^2 and you have B=2. For x, it becomes 9=2A+C. A is equal to -5 (from the x^3), so you can substitute and get c=19. Repeat for the x^0 term (the constants), and you get 2=2B+D. Plug in the value for B, 2, and get 2=4+D, which then becomes D=-2. That's how you get the answer and I hope this helps somebody.
The values are A=-5, B=2, C=19 and D=-2
What is partial fraction?Partial fractions are the fractions used for the decomposition of a rational expression. When an algebraic expression is split into a sum of two or more rational expressions, then each part is called a partial fraction. Hence, basically, it is the reverse of the addition of rational expressions.
Given:(-5x³+2x²+9x+2) / x²+2 =(Ax + B)/x²+2 + (Cx + d)/x²+2 .......(1)
First, we have to perform the long division as follows
The long division gives
(-5x³+2x²+9x+2 )/ x²+2= ( -5x+2)+ (19x-2)/ x²+2
Now, we have to find the partial fraction for (19x-2)/ x²+2
But, as denominator cannot be factored, So no partial fraction can be calculated.
Thus, (-5x³+2x²+9x+2 )/ x²+2= ( -5x+2)+ (19x-2)/ x²+2
Comparing it with equation (1), we get
Hence, A=-5, B=2, C=19 and D= -2

find the equation of the line tangent to the graph of f at (1,4), where f is given by f(x)=2x^3-3x^2+5
Answer:
[tex]y = 4[/tex]
Step-by-step explanation:
First, find the derivative of f:
[tex]\displaystyle \begin{aligned} f'(x) & = \frac{d}{dx}\left[ 2x^3 - 3x^2 + 5\right] \\ \\ & = 6x^2 - 6x \\ \\ & = 6x(x-1)\end{aligned}[/tex]
Find the instantaneous slope at x = 1:
[tex]\displaystyle \begin{aligned} f'(1) & = 6(1)((1)-1) \\ \\ &= 0 \end{aligned}[/tex]
From the point-slope form, find the equation of the line:
[tex]\displaystyle \begin{aligned}y - y_1 & = m(x-x_1) \\ \\ y - (4) & =(0)(x-(1)) \\ \\ y & = 4 \end{aligned}[/tex]
In conclusion, the equation of the tangent line is y = 4.

So
YZ=2(66)=132Apply Pythagorean theorem
[tex]\\ \tt\hookrightarrow VY^2=XS^2-VS^2=80^2-48^2=6400-2304=4096\implies VY=64[/tex]
Answer:
XS = 80
YZ= 132
VY = 64
Step-by-step explanation:
Firstly, SU is a perpendicular bisector
so, UV= UZ and YZ = 2(66) = 132
Each median bisect each other at centre with the ratio 2 : 1
therefore ZS = 80 = XS
now , by using P.G.T
VY² = XS²-VS²
=> 80²-48²
=> 6400-2304

Ava cannot spend more than $100 on food for a party. The lemonade will cost $19 and she wants to spend the rest on pizza. Each pizza costs $7.
How many pizzas can she buy?
Enter your answer in the box.
___ pizzas
Answer and Step-by-step explanation:
So for this question, we need to create an equation. We will use one of the most common forms of equations of math, which would be the linear equation of y=mx+b. The only difference is, we need to change the = to a ≥ symbol, meaning greater than or equal to, because the 100 dollars needs to be more or equal to the amount spent. But we cannot solve this problem until we know where everything goes.
So, the 100 is all she can spend, so this is where the ≤ comes in handy. She can use less than or equal to the amount of 100 dollars for the food for this party. And because she started out with 19 dollars, that can be added into the problem. So far we have:
100 ≥ __x + 19.
Now we need to find what the missing part of the equation is. But first let's change the x to p in this equation so that it is easier to understand. The p stands for the amount of pizzas purchased. Each pizza costs 7 dollars, so the equation should look like this:
100 ≥ 7p + 19. Now we solve for p.
-19 - 19 Subtract 19 from both sides to cancel out the positive 19 (+ 19).
81 ≥ 7p Divide 7 into 81 to single out p.
7 7 So p = 81/7. But we can't have 81/7 of a pizza, so we convert this to a decimal then round. So: 11.57142857… is the decimal form.
Now we need to round, because that is way too big. So, we round to the nearest whole number. So we look at the placement behind it (The tenths placement in this situation). Because the placement behind it (5) is on the 5 - 9 scale, the placement before it gets rounded up.
So, Ava can buy 12 pizzas.
I hope that this helps.

The solutions to a certain quadratic equation are x= -4 and X = 3. Write the equation in standard form below.
[blank] +x [blank] [blank] = 0
Answer:
x² + x - 12 = 0

If x = -4 and x = 3 are solutions to a quadratic equation, then
(x + 4)(x - 3) = 0
Expand the brackets: x² - 3x + 4x - 12 = 0
Combine like terms: x² + x - 12 = 0
