Answer:
k=2 k=-8
Step-by-step explanation:
X = gummy bears, y = jelly beans, z = gobstoppers
x + y + z = 13
x + 2y + 2z = 20
x = 3y
3y + y + z = 13
4y + z = 13
3y + 2y + 2z = 20
5y + 2z = 20
4y + z = 13....multiply by -2
5y + 2z = 20
-----------------
-8y - 2z = -26
5y + 2z = 20
---------------add
-3y = -6
y = 2........2 lbs jelly beans
x = 3y
x = 3(2)
x = 6....6 lbs gummy bears
x + y + z = 13
6 + 2 + z = 13
8 + z = 13
z = 13 - 8
z = 5........5 lbs gobstoppers
so we have : 6 lbs gummy bears (x), 2 lbs jelly beans (y), and 5 lbs gobstoppers (z)
Answer:
A
Step-by-step explanation:
Arc length is given by the formula:
Where <em>r </em>is the radius and θ is the central angle, in degrees.
The windshield wiper has a radius of 20 inches and a central angle of 150°. Hence:
Use a calculator:
Our answer is A.
Hey there!
1 + 2 = 3
2/8 + 5/8 . . .
= 7/8 (denominator stays the same)
3 + 7/8 = 3 7/8
The sum of the numbers 1 2/8 and 2 5/8 is 3 7/8.
1 2/8 + 2 5/8 = 3 7/8.
Hope this helps you.
Have a great day!
