Step-by-step explanation:
x - 2/5= 7
Add 2/5 to each side
x - 2/5 + 2/5 = 7+2/5
x = 7 2/5
or if
( x-2) /5 = 7
Multiply each side by 5
(x-2) /5 *5 = 7*5
x-2 = 35
Add 2 to each side
x-2+2 = 35+2
x = 37
We want to solve 9a² = 16a for a.
Because the a is on both sides, a good strategy is to get all the a terms on one side and set it equal to zero. Then we apply the Zero Product Property (if the product is zero then so are its pieces and Factoring.
9a² = 16a
9a² - 16a = 0 <-----subtract 16a from both sides
a (9a - 16) = 0 <-----factor the common a on the left side
a = 0 OR 9a - 16 =0 <----apply Zero Product Property
Since a = 0 is already solved we work on the other equation.
9a - 16 = 0
9a = 16 <----------- add 16 to both sides
a = 16/9 <----------- divide both sides by 9
Thus a = 0 or a = 16/9
Answer: 7.1 yd
Step-by-step explanation:
the formula for arc length is 2πr(x/360), x being the central angle
input the values, so the equation would be 2π9(45/360), which equals 7.1
A is your answer hope this helps
Answer:
There are 0.0328 centimeters in 1 foot.
Step-by-step explanation:
Given : There are 12 inches in 1 foot.
To find : How many centimeters are there in 1 foot?
Solution :
1 foot = 12 inches
and 1 inch = 2.54 centimeter
So, 12 inches = 
centimeter
12 inches = 30.48 centimeter
i.e. 1 foot = 30.48 centimeter
Then, 1 centimeter = 
foot
1 centimeter = 0.0328 foot
Therefore, there are 0.0328 centimeters in 1 foot.
