This is because 180-95= 85 which would make 8x+5= 85
Subtract 5 from both sides and get 8x=80
Then, divide 8 from both sides and get x=10
Step-by-step explanation:
95+8x+5=180
100+8x=180
8x=80
X=80/8
x=10

2. A tree casts a shadow 25m long. At the same time, a signpost next
to the tree casts a shadow 6m long. The signpost is 3.5m tall. How
tall is the tree?
(10 pts.)
Answers
Answer:
The height of the tree is 14.85[tex]\bar 3[/tex] m
Step-by-step explanation:
The length of the shadow cast by the tree = 25 m
The length of the shadow cast by the signpost = 6 m
The height of the signpost = 3.5 m
Therefore, by similar triangles, we have;
Let θ, represent the angle formed by the line extending a line from the tip of the shadow, to the tip of the object and let x represent the height of the tree, we have
Tan(θ) = Opposite/Adjacent = Height of the object/(The length of the shadow)
∴ Tan(θ) = 3.5/6 = x/25
x = 25 × 3.5/6 = 14.58[tex]\bar 3[/tex]
The height of the tree = x = 14.85[tex]\bar 3[/tex] m

an article after allowing a discount of 20% on its marked price was sold at a gain of 20% had it been sold after allowing 25% discount would have been of gain of rupees 125 find the Marked price of the article
Answers
Answer:
Rs 120
Step-by-step explanation:
Let MP = m
Discount = 25% of MP = m/4
SP = MP - Discount
= m - m/4 = 3m/4
If profit is 20%, CP = 3m/4 x 100/120 = 5m/8
=> Profit = 3m/4 - 5m/8 = m/8
Given Profit - Discount = Rs 15
=> |m/8 - m/4| = 15
m/8 = 15
m = Rs 120

the price of a necklace was increased by 10% to £150. what was the price before the increase
Answers
Answer:
$135
Step-by-step explanation:
10% of 150 = 15
150 - 15 = 135
Increased by 10%.
So, 150 x 0.10 = 15
The necklace was increased by £15.
The price before the increase is £150 - £15.
This amount is £135.

Step-by-step explanation:
Imagining living a life for five hundred years in the future, can have two perspectives considering the reality of today's society.
Let us suppose that we currently overcome all challenges related to preserving the environment, sustainable consumption, violence, and racial discrimination. Well, considering that point of view, a typical day five hundred years from now would be a lot of fun, I imagine that we would have great biodiversity preservation centers, people would be more cordial with others, everyone would have access to education and essential rights, and we would use more bicycles as a means of transport, because even if they had already managed to invent teleportation, the bicycle would still be a good option for the practice of physical exercises.

369.75 + 330.90 + 287.00 = 997.65
997.65 / 3 = 332.55
Therefore, the average Cliff's average payment for utilities is $332.55 per month. Hope you ace your test! :)

Answer:
2√6
Step-by-step explanation:
Because 2 multiplied by itself is 4
4 times 6 is 24
You multiply 2 by itself is because of the square root
Square roots are the opposite of exponents
Just like how addition is the opposite of subtraction
2^2 is 4
√4=2
Since 24 has a 4 in its multiple you can simplify it into 2 and put it on the outside

Step-by-step explanation:
Sum the parts of the ratio, 5 + 3 = 8 parts
Divide the quantity by 8 to find the value of one part of the ratio.
192 Kg ÷ 8 = 24 Kg , thus
5 parts = 5 × 24 Kg = 120 Kg
3 parts = 3 × 24 Kg = 72 Kg

To find these out you have to use the strategy of P (parenthesis) E (exponents) M (multiplication) D (division) A (addition) S (subtraction)
3 - 4 x 2 The first thing you need to do is do the multiplication part first, since subtraction is the last thing you need to do. You multiply 4 and 2 and get the answer of 8, then subtract 3 which is 5
5 x 3 - 4 The first thing you need to do is multiplication 5 x 3 which equals 15 and then do 15 - 4 = 11
15 ÷ (3 x 5) x 2 The first thing you do is you do the P (parenthesis) which is (3x5) which equals 15. Then you multiply 15 with 2 which is 30 and then divide 30 with 15 which is 2
5 + 3 x 2 ÷ 6 First you need to do the Multiplication which is 3 x 2 which equals 6, and then you do the division, which is 6 ÷ 6 which is 1. Then add 5 to the 1 which is 6.
