Answer:
40 degrees
Step-by-step explanation:
Supplementary angles are angles in which their measures combined add up to 180 degrees. So we can set up an equation:
140+x=180
x=40
So the other supplementary angle is 40 degrees
Answer:
$3.51
Step-by-step explanation:
1 pound is $2.39 so divide by 2 and round up to the nearest whole number which is $1.12. Add $1.12(The cost of 0.5 pounds) to $2.39(The cost of 1 pound) to get $3.51 as your total.
The answer is x=3
1x=3 so that means that one x is the same as 3
3y+21+8y
11y+21 is the answer
Answer:
25.12
Step-by-step explanation:
Formula: 2πr, r = d/2
Given: π = 3.14, d = 8
Sub: r = 8/2
Simplify: r = 4
Sub: 2(3.14)(4)
Simplify: 6.28(4)
Solve: 25.12
