Answer: 9.
Step-by-step explanation: First take 6 and divide it by 2, and then multiply by 3. This gets to the correct answer of 9.
Answer: The answer is 9.
Step-by-step explanation: First I take 6 divided by 2 and then I multiply by 3 to get the correct answer of 9. Or I could show you an equation that looks like this from: 6÷2(1+2) to 3*3=9; therefore, 1 is incorrect answer because it has an order of operations and 9 is the correct answer because it doesn’t have an order of the operations.

The ratio of collectible cards Deshawn owns to cards that Stephanie owns is 5:2 Stephanie has 36 cards how will the ratio of Deshawn's cards to Stephanie's cards change if they both sell half there cards.
Answers
Given :
The ratio of collectable cards Deshawn owns to cards that Stephanie owns is 5:2.
Stephanie has 36 cards.
To Find :
How will the ratio of Deshawn's cards to Stephanie's cards change if they both sell half there cards.
Solution :
Number of card Deshawn had, n = 5/2 × 36
n = 90 .
Number of card after they sell half there cards :
[tex]n_D = \dfrac{90}{2}=45[/tex]
[tex]n_S=\dfrac{36}{2}=18[/tex]
Therefore, new ratio is [tex]\dfrac{45}{18}=5 : 2[/tex].
So, new ratio will be same.

Point S is on line segment \overline{RT} RT . Given RT=4x,RT=4x, ST=5x-10,ST=5x−10, and RS=6,RS=6, determine the numerical length of \overline{ST}. ST .
Answers
Answer:
[tex]ST = 10[/tex]
Step-by-step explanation:
Given
[tex]RT =4x[/tex]
[tex]ST = 5x - 10[/tex]
[tex]RS = 6[/tex]
Required
Determine ST
Since S is on RT, we have that:
[tex]RT = RS + ST[/tex]
[tex]4x = 5x - 10 + 6[/tex]
[tex]4x = 5x - 4[/tex]
[tex]4x - 5x= - 4[/tex]
[tex]-x= - 4[/tex]
[tex]x= 4[/tex]
Substitute 4 for x in [tex]ST = 5x - 10[/tex]
[tex]ST = 5 * 4 - 10[/tex]
[tex]ST = 20 - 10[/tex]
[tex]ST = 10[/tex]

1. Find the value of x and y.
2. In an A-figure house, the two congruent sides extend from the ground to form a 34° angle at the peek. What angle does each side form with the ground?
Answers
Problem 4
Note the markings at the top indicate that angle y represents half the angle BAC. In other words, we need 2 copies of angle y to make up angle BAC.
So we know that angle BAC = 2y
Due to the fact that triangle ABC is isosceles, we know that base angles B and C are congruent to 47.
Focusing on triangle ABC we have
A = 2yB = 47C = 47So,
A+B+C = 180 .... for any triangle, the angles always add to 180
2y+47+47 = 180
2y+94 = 180
2y = 180-94
2y = 86
y = 86/2
y = 43
Turn your attention to triangle ABD.
Here we have
angle A = y = 43angle B = 47angle D = xWe'll use the same idea as above, that all angles add to 180, to get...
A+B+D = 180
y+47+x = 180
43+47+x = 180
x+90 = 180
x = 180-90
x = 90
Answer: D) x = 90, y = 43===================================================
Problem 5
Let x be the angle formed by the diagonal sides and the horizontal ground. This is considered the base angle because this triangle is isosceles.
We have two base angles x and the third angle up top is 34
x+x+34 = 180
2x+34 = 180
2x = 180-34
2x = 146
x = 146/2
x = 73

Step-by-step explanation:
An equation with zeros at these numbers could be put in form x = number.
So, (x-3) could be set to 0 to get x=3.
So, you can look at these "answers" they give you and work backward to get:
(x-3)(x+2/5)(x-3i)

-5x^2/-5 - 13/5x -6/5
Divide all terms by 1/5 (which is the same as multiplying each term by 5)

Answers
Answer: 120
Step-by-step explanation:
From the question, we are informed that there are 10 people in a math club and that three people will be chosen for the Pi Day committee.
The number of different ways that the club members can structure the committee goes thus:
This can be solved by:
nCr = n! / r! (n - r)!
where n = 10
r = 3
= n! / r! (n - r)!
= 10! / 3! (10 - 3)!
= (10 × 9 × 8) / (3 × 2)

Solve
2/7 x 28 = 8
C = 8
The value of c is 8 in the proportion 2/7=c/28.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given proportion is 2/7=c/28
Two divided by seven equal to c divided by twenty eight.
We have to find the value of c.
We find the value of c by applying cross multiplication
28×2=7c
56=7c
Divide both sides by 7
56/7=c
Divide numerator and denominator by 7
We get c=8
Hence, the value of c is 8 in the proportion 2/7=c/28.
