Answer:
10. First you multiply both sides by 3, making it 2x + 5 = 24
Then you subtract 5 from both sides making it 2x = 19
You dive both sides by 2 making x = 9.5
The answer is x = 9.5
11. First you need to find how much you need to pay each year. 12,000 x 0.05
you can make it easier by changing it to 120 x 5 = 600
You need to pay that for three years so 600 x 3 = 1800
Plus you need to pay the original money. 12,000 + 1,800 = 13,800
The answer is $13,800
12. First you change kilometers into centimeters. 172 km is 172,000 meters. 172,000 meters is 17,200,000
Then, you need to do 17,200,000 ÷ 500,000 but you can make it simple and do 172 ÷ 5 = 34.4
The answer is 34.4 cm
To answer this, you first have to find 3/8 of 4200 by multiplying those two numbers.
First, multiply the numerators.
4200x3=12600
Next, multiply the denominators.
1x8=8
You end up with 
.
This fraction can be simplified to 1575.
All that's left is to subtract that number from 4200.
4200-1575=2625
The final answer is 2625 adults in Lakeview have children.
Answer:
D
Step-by-step explanation:
Mathematically, for us to have a right triangle, Pythagoras’ theorem must be obeyed
From the theorem, the square of the hypotenuse (longest side) equals the sum of the squares of the two other sides
Let us take a look at the given set of numbers:
2 square is not same as 1 squared + 1 squared
9 squared is not equal to 3 squares + 5 squared
7 squared is not equal to 4 squared + 3 squared
But;
root 2 squared equals 1 squared plus 1 squared and that is our answer
<u>Answer-</u>
From 61.21 km on a clear day you could see from the top of the Eiffel Tower.
<u>Solution-</u>
From the attachment,
OA = Distance between the top of the Eiffel Tower and center of the earth = 6240 km + 300 m = 6240 km + 0.300 km = 6240.3 km
OB = Radius of the earth = 6240 km
Applying trigonometric properties,
So,
So, the arc length will be,
Therefore, from 61.21 km on a clear day you could see from the top of the Eiffel Tower.
