Answer:
Step-by-step explanation:
2x + 4 + x + 23 = 180
3x + 27 =180
3x = 153
x = 51
Answer:
x = 13/4
Step-by-step explanation:
(2x/3)-(5/3)=(1/2)
Multiply everything by 3
2x - 5 = 3/2
Get the x term on it's own by adding 5 to both sides
2x = 3/2 + 5
2x = 3/2 + 10/2
2x = 13/2
Divide by 2 to get x on it's own
x = 13/2 ÷ 2 = 13/2 * 1/2 = 13/4
Answer:
Minimum height is 7.25ft and maximum height is 7.75ft
Step-by-step explanation:
You measured to the nearest half foot, so the greatest possible error is 0.25 foot.
Minimum height= measured value-possible error= 7.5-0.25= 7.25ft
Maximum height= measured value+possible error= 7.5+0.25= 7.75ft
Answer:
4
Step-by-step explanation:
(24+4) ÷ 2 = (24 ÷ 2) + (4 ÷ 2)
28÷2 = 14
Check:
24÷2 = 12
4÷2 = 2
12+2=14
look at the hundreds place, if it is 5oo or greater than you round up, if it is less than 5 you round down
in 39,176, the hundreds place is one hundred, which is less than 5, so round it to 39,000
