Answer:
A. (3,0)
Step-by-step explanation:
When the equations are graphed, the solution is where the two graphs cross. For the red line and the blue line, the cross at (3,0)
We can check this by substituting x=3 into both equations and seeing if we get y=0
y = -x+3
y = -3+3
y =0
y = x-3
y = 3-3
y=0
In both cases, we got y=0.
Therefore (3,0) is a solution to both equations and since it solves both equations, it solves the system.
2.5= 2 1/2
just do 10/20= .5 so 7.5
8.2= 8 2/10 which simplifies to 8 1/5
2.88=2 <span>22/<span>25

3/6= 7.5
3 1/4= 3.25
i couldn't see the other ones except for also 12
2.1= 2 1/10
Answer:
Brad needs 37.68 ft of plastic edging to enclose the flower garden, in terms of "pi" it is 12π only.
Step-by-step explanation:
Given:
Diameter of the circular flower garden = 12 ft
We have to find the measure of the plastic edging Brad need to have.
So,
We have to find the length of the edge of the circular garden for circular object the measure of its length has a special name we call it circumference.
And it is very well known to us that:
For any circle the ratio of its circumference and its diameter is equivalent to pie (π) which is equal to 3.14
Then,
⇒
In the above question we have to find the measure of its circumference.
⇒
⇒
⇒ ft
⇒ Or
⇒
⇒ ft
Brad needs 37.68 ft of plastic edging to enclose the flower garden, in terms of "pi" it is 12π only.
Given:
Selling price of bird feeder = 40 each
Discount percent = 7%
To find:
The final price of the bird feeder after the discount.
Solution:
We know that,
Final price = Selling price - Discount
=
=
=
Therefore, the final price of the bird feeder after the discount is 37.2 each.
hello!
Your answer is 150°
the 30° angle and ∠1 are a linear pair, and are supplementary. therefore they add up to 180°
take the 30°, subtract it from 180°, and you get 150°
equation:
∠1 + 30° = 180°
subtract 30 from both sides and you get 150°
I hope this helps, and have a nice day!
