What is the value of x?
Step-by-step explanation:
Hello! x = 24 This is a complementary angle so it will add up to 90 degrees in total so 24 × 3 = 72 and 72 - 6 = 66 and 66 + 24 = 90 so x = 24 HOPE THAT HELPS!
Answer:
X = 24
Step-by-step explanation:
so you will have to add all the angles and get 90
3x - 6 +x=90
4x =96
x=24
check your answer.
3 x 24
72 -6 = 66
66 +24 = 90

The price of an item decreased by 10% each week for 4 weeks. What was the approximate percent of decrease of the price of the item after 4 weeks?
A 34%
B 40%
C 60%
D 66%
Answer:
34%
Step-by-step explanation:
Answer:
A) 34%
Step-by-step explanation:
Lets say that the price of this object was $100.
Then, we know that each week the price is reducing by 10%, so therefore, we take 10% of $100, and we have $10
If we subtract that from $100, ($100-$10), we find that the price has come down to $90 after the first reduction in the first week. We will now do this process three more times to get to the four weeks total.
10% of $90 dollars is 9 dollars, so therefore the price reduces to $90-$9, $81 after the second reduction in the second week.
Then we take 10% of $81 and then get $8.1. We subtract that from $81 and get $72.9
Then for the final reduction in the fourth week, we take 10% of $72.9, and we get $7.29. Take that from $72.9, and you get $65.61, which we can round to $66.
The question however asks how much was the approximate percantage in decresse over the 4 weeks. We see that the object went from $100 to $66, which is $34 decrease.
Now we simply find what percantage of $100 is $34, and that is 34%, which gives you option A.
Hope this helped.
please help me on math
Answer:
Hello! answer: b = 75
Step-by-step explanation:
We have to find b so we have to work backwards to find the answer the steps would be to find c^2 subtract that by a^2 and then you get b^2 and have to find out what multiplied by itself equals b^2 so... 85 × 85 = 7225 40 × 40 = 1600 7225 - 1600 = 5625 75 × 75 = 5625 therefore b = 75 hope that helps!

What is a Geometric Series?A sequence of numbers such that the consecutive term is increasing or decreasing by a fixed ratio is called a geometric series.
The standard equation for geometric series is
Tₙ = a₁ rⁿ⁻¹
The sum of an infinite geometric series is given by
S = a₁/(1-r)
where a₁ is the first term and r is the common ratio.
The graph of an infinite series curves away from its sum.

Solve for x the triangles In Each pair LMN~LRS
Please help quickly and show work pleasee
Given:
[tex]\Delta LMN\sim \Delta LRS[/tex]
To find:
The value of x.
Solution:
We have,
[tex]\Delta LMN\sim \Delta LRS[/tex]
We know that the corresponding sides of similar triangles are proportional. So,
[tex]\dfrac{LM}{LR}=\dfrac{LN}{LS}[/tex]
[tex]\dfrac{18}{2x-18}=\dfrac{30}{10}[/tex]
[tex]\dfrac{18}{2x-18}=3[/tex]
[tex]18=3(2x-18)[/tex]
Using distributive property, we get
[tex]18=3(2x)-3(18)[/tex]
[tex]18=6x-54[/tex]
[tex]18+54=6x[/tex]
[tex]72=6x[/tex]
Divide both sides by 6.
[tex]\dfrac{72}{6}=x[/tex]
[tex]12=x[/tex]
Therefore, the correct option is A.
Which expression is equivalent to (-18) - 36n?
Answer:
D
Step-by-step explanation:
-18 - 36n = -6(3 + 6n).
Use distributive property.
-6(3 + 6n)
-18 + (-36n)
-18 - 36n
-18 - 36n = -18 - 36n
Have a nice day!
Answer:
D. -6 (3 + 6n)
Step-by-step explanation:
When you distribute [tex]-6 (3 + 6n)[/tex], you get [tex]-18 + -36n.[/tex]
[tex]-18 + -36n = (-18) - 36n.[/tex]
Each bag of pears weighs 1 kg 160 gram. What is total weight of a sack which contains 5 bags of pears?
Answer:
5 kg 800 grams
5800g
Step-by-step explanation:
the first step is to convert 1kg to gram
100 kilogram = 1 gram
1kg x 1000 = 1000g
1kg 160 gram = 1000 + 160 = 1160 gram
If 1 sack weighs 1160 g
5 sacks = 1160g x 5 = 5800 gram
or 5800 / 1000 = 5 kg 800 grams

solve by elimination 5x+2y=-11 and 3x+2y=-9
Answer:
[tex]5x + 2y = - 11 - - - (a) \\ 3x + 2y = - 9 - - - (b) \\ (a) - (b) : \\ 2x + 0y = - 2 \\ x = - 1 \\ (3 \times - 1) + 2y = - 9 \\ - 3 + 2y = - 9 \\ 2y = - 6 \\ y = - 3 \\ { \boxed{x = - 1}} \\ { \boxed{y = - 3}}[/tex]
Answer:
(- 1, - 3 )
Step-by-step explanation:
Given the 2 equations
5x + 2y = - 11 → (1)
3x + 2y = - 9 → (2)
Subtract (2) from (1) term by term to eliminate y
2x = - 2 ( divide both sides by - 2)
x = - 1
Substitute x = - 1 into either of the 2 equations and solve for y
Substituting into (1)
5(- 1) + 2y = - 11
- 5 + 2y = - 11 ( add 5 to both sides )
2y = - 6 ( divide both sides by 2 )
y = - 3
solution is (- 1, - 3 )
