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.

What’s the correct answer for this? Any help would be appreciated
Please help me with this.
Image attached below! Thank you.
Answer:
C
because:
[tex]y = 0.074x + 50.48 \: \: \\ \: when \: x = 2158 \\ y = 0.074(2158) + 50.48 \\ y = 210 \\ when \: x = 2040 \\ y = 0.074(2040) + 50.48 \\ y = 200 \\ [/tex]
So the equation can be used to calculate fair housing prices is:
[tex]y = 0.074x + 50.48[/tex]
Maurice has completed 72 pages of the research paper he is writing. That is 90% of the required length of the paper. What is the required length of the paper?
Answer:
its 100 pages ................
Answer:
80
Step-by-step explanation:
When we first look at this, it generally says "90% of what number is 72?" so that's what we can do.
We can change 90% into a decimal, and put in x, which is what our answer will be!
[tex]0.9*x=72[/tex]
We can multiply both sides of this equation by 100, and then divide by 90. After all of this, we have
[tex]x=72*10/9[/tex], which is 80.
Add parentheses to make true.
2(with exponent of 3) +7.8 + 4 = 30.
Answer:
8 (hopefully)
Step-by-step explanation:
Exponents and Fractions always get dealt with before Math Symbols and Parentheses.
But other than that, you ALWAYS do times or divide from left to right, than plus or minus left to right (unless there's a parentheses, go for the number in the parentheses).
2 by the power of 3 (or 2^3) splits into three twos.
2 * 2 = 4 * 2 = 8 (2^3 = 8)
7 * 8 = 56
56 divided by 4 = 14
8 + 14 = 22
Long story sort
2^3 + 7 * 8 */. 4
8 + 7 * 8 */. 4
8 + 56 */. 4
8 + 14
22
Now than I do not remember what you're supposed to with the "= [Number]" but I do believe you're supposed to sum the left and the right. So I do believe it's 8, now than remember this is not an exact answer, due to not knowing what it's properly to be.
Answer:
(2³ +7)·8÷4 = 30
Step-by-step explanation:
You want to add parentheses to make a true statement from ...
2³ +7·8÷4 = 30
Order of operationsWe recognize that 2³ +7 = 15 and 8÷4 = 2, and the product of these is 30. So, we need to insert parentheses to make (2³ +7) be evaluated before multiplying by 8 and dividing by 4:
(2³ +7) · 8 ÷ 4 = 30

The indication of QRS and TUV are similar is QRS ~ TUV.
What is Similarity?Similar triangles are triangles that have the same shape but differ in size. Similar items include all equilateral triangles and squares with any side length. In other words, if two triangles are identical, their corresponding angles and sides are congruent and in equal proportion. The " ~ " sign here denotes the resemblance of triangles.
The three-sided polygon is the triangle. The following is the criteria for triangle similarity:
Corresponding angles of both triangles are equal, and corresponding sides of both triangles are proportional to each other.
In Triangle QRS and TUV the similarity sign is used.
We know the ≅ is the sign of Congruence.
and, ~ is the sign of Similarity.
So, the sign of Similarity is QRS and TUV.

Which values from the set {-6, -4, -3, -1, 0, 2} satisfy this inequality? 1/2x+3>5
Answer:
-12x+3 greater than or equal to 5
-12x greater than or equal to to 2
To turn the negative sign of -12x into positive, we multiply both sides by minus, which shifts the inequality sign.
So, 12x less than or equal to 2
x is less than or equal to 1/6
Therefore, 0, -1, -3, -4 and -6 satisfy this inequality

What is the slope of the line that passes through the points (-7, -2) and (-15, -14)
The slope of the line that passes through the points (-7, -2) and (-15, -14) is 3/2.
The given coordinate points are (-7, -2) and (-15, -14).
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The formula to find the slope of a line is slope = (y2-y1)/(x2-x1)
The slope of the line is
Put (x1, y1) =(-7, -2) and (x2, y2)=(-15, -14)
Slope = m= (-14-(-2))/(-15-(-7))
= -12/(-8)
= 3/2
Therefore, the slope of the line that passes through the points (-7, -2) and (-15, -14) is 3/2.

Ms. reed makes salad dressing by combining oil and vinegar. she combines 8 fluid ounces of oil and 3 fluid ounces of vinegar to make one batch. Ms. Reed makes 3 batch of salad dressing. How many total cups of salad dressing does she makes ?
By performing a change of units, we will see that she did make 1.375 cups of salad dressing.
How many total cups does she make?First, we know that she combines 8 oz of oil and 3 oz of vinegar, then the total volume in ounces is:
V = 8oz + 3 oz = 11 oz
Now we want to know how many cups there are in 11 ounces, so we need to perform a change of units.
We know that:
1 oz = 0.125 cups
Then we can write:
11 oz = 11*(1 oz) = 11*(0.125 cups) = 1.375 cups
