Twenty people attended a going away party for Zach.The guest left in groups of 2.By 9:00,x groups had left.Rewrite the number of guests remaining at 9:00 as a sum.
Answer:
The number of guests remaining at 9:00 is;
(20-2x)
Step-by-step explanation:
From the question, we are told that x groups have left
Since they are leaving in groups of 2, x groups means a total of x * 2 = 2x
So we have 2x left out of a total 20; the people remaining at the party will be;
20-2x

What is the common ratio of 9, 81, 729. -6561
Given:
Consider the given sequence is 9, 81, 729, 6561.
To find:
The common ratio.
Solution:
We have,
9, 81, 729, 6561
Here,
First term = 9
Second term = 81
Divide the second term by first term to get the common ratio.
[tex]r=\dfrac{81}{9}[/tex]
[tex]r=9[/tex]
Similarly,
[tex]\dfrac{81}{9}=\dfrac{729}{81}=\dfrac{6561}{729}=9=r[/tex]
Therefore, the common ratio is 9.

- Question 11
Mrs. Pitoya has 30 apples and is buying more apples in crates containing 20 apples each. She needs 130 apples for a harvest celebration at her school,
Which equation and solution correctly represent x, the number of crates of apples Mrs. Pitoya needs to buy?
Answer:
Mrs pitoya has to buy 9 crates of apples
Answer: She only needs to buy 5 more crates of apples.
30 + 20(x) = 130
30-30+20(x)=130-30
20x = 100
x = 5

Answer:
x = 58°, y = 32°
Step-by-step explanation:
all sides are equal, hence it is a rhombus.
in a rhombus, diagonals meet at 90degree..
hence in triangle,
58 + 90 + z = 180 (asp of a triangle.)
z = 32
y = z ( alternate interior angles as lines are parallel in rhombus)
y = 32
in the bigger triangle,
angles opposite to equal sides are equal, hence,
32 + 32 + (58 + x) = 180 ( angle sum property of a triangle,)
hence, x = 58
therefore,
x = 58°, y = 32°
Two ordered pairs that would form a direct variation

What is the missing value:
[tex]\frac{16}{1}[/tex] =[tex]\frac{x}{2 \frac{1}{2} }[/tex]
Answer:
[tex] x = 40 [/tex]
Step-by-step explanation:
[tex] \dfrac{16}{1} = \dfrac{x}{2 \frac{1}{2}} [/tex]
Convert the mixed numeral into a fraction.
[tex] \dfrac{16}{1} = \dfrac{x}{\frac{5}{2}} [/tex]
Multiply both sides by 5/2.
[tex] \dfrac{5}{2} \times \dfrac{16}{1} = x [/tex]
[tex] x = \dfrac{80}{2} [/tex]
[tex] x = 40 [/tex]

Answer:
x > 17
Step-by-step explanation:
Given equation:

2x - 12 + 7 > 3x - 4x + 32 ^ Distributive Property
2x - 19 > -1x + 32 ^ Combine like-terms
3x - 19 > 32
3x > 51
