Hi there!
Step-by-step explanation:
First, you subtract by 8 from both sides of an equation.
x+8-8>14-8
Then, you subtract by the numbers from left to right.
14-8=6
The answer must have a positive sign.
Answer: →→ x>6
Hope this helps!
Have a nice day! :)
Answer:
volume is about 113.1 in^3
Step-by-step explanation:
V=(pi)(r^2)(h)
V=(pi)(2^2)(9)
V=(pi)(4)(9)
V=(pi)(36)
V= about 113.1 in^3
Answer:
The answer is 10.9
Step-by-step explanation
#1 think of the formula of the area
length x width = area
#2 do the oposite of what you would to to find the area to find the width
82.84➗7.6 = 10.9
#3 check your answer
7.6 x 10.9 = 82.84
#3 answer
width= 10.9
Hope this helps!!!!!!
If gold coin weigh 20 grams. If the coin contains gold,copper and tin and in the ratio 4:3:1 then 10gm of gold is present in coin.
A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given,
A gold coin weigh 20 grams
the coin contains gold, copper and tin and in the ratio 4:3:1
We need to find the amount of gold in the coin.
Now let us add the ratio.
4x+3x+x=20
8x=20
Divide both sides by 8.
x=2.5
The amount of gold in coin is 4x.
4(2.5)=10 gm
Hence, 10 gm of gold is present in 20 grams of coin.
