Answer:
solution for n is 
Step-by-step explanation:
Given an equation containing one variable n.
The equation is as follows:
To solve for n we can subtract 3/4 from both the sides
The result is
Verify:
Substitute the answer in the given equation.
Both sides equal thus proving our correctness of answer.
X - y = -3
Move constant to the left by adding its opposite to both sides
x - y + 3 = -3 + 3
The sum of two opposites equals
your answer would be: x - y + 3 = 0
Answer:
0.7 seconds
Step-by-step explanation:
You have to subtract both lap times, but before doing so you need to know what 2/5 is in decimal form. To do so, you must do 2 divided by 5, getting 0.4 seconds as it's a fraction converting to decimal. This means Fam swam 29.4 seconds, which instead of 2/5, you have 0.4 as your converted answer, so you would substitute it after 29. Then, you would do 29.40 subtracted by 28.7 and get 0.7 seconds as your answer to find out the difference of their swim times.
Answer:
25π cm^2 ≈ 78.5 cm^2
Step-by-step explanation:
The base is a circle with a radius of 5 cm. Its area is given by ...
A = πr^2
A = π(5 cm)^2 = 25π cm^2 ≈ 78.5 cm^2
