Answer:
1000
Step-by-step explanation:
40x50=2000
2000/2=1000
Multiply the first equation my 2 and than subtract the two equations to eliminate x
6x+16y=60-
6x+7y=6
9y=54
Y=6
Then plug in y to one of the equations
6x+7(6)=6
6x+42=6
6x=-36
X=-6
X=-6 Y=6
Answer:
<h3>The answer is 32cm</h3>
Step-by-step explanation:
Circumference of a circle = 2πr
where
r is the radius
To find the radius of the mat substitute the value of the circumference into the above formula and solve for the radius
Circumference = 200cm
200 = 2πr
Divide both sides by 2π
r = 31.83098
We have the final answer as
<h3>radius = 32 cm to the nearest whole number</h3>
