Answer:
25, 45, 30
Step-by-step explanation:
(a)
The line is divided into 3 parts, that is 75 ÷ 3 = 25
The 1 part is then 25 units
(b)
The line is divided into 5 parts , that is 75 ÷ 5 = 15
The 3 parts are then 3 × 15 = 45 units
(c)
The line is divided into 5 parts, that is 50 ÷ 5 = 10
The 3 parts are then 3 × 10 = 30 units
Answer: 20
Step-by-step explanation:
You find the mean by adding up all the numbers in a data set, then dividing by the number added.
18 + 15 + 22 + 18 + 25 + 19 + 23 + 20 = 160
We added 8 numbers together, so we divide 160 by 8
160/8 = 20
Answer:
x = 7
Step-by-step explanation:
the smallest common denominator between 2 3 and 6 is 6. Multiply the original equation by 6
- 6(x/3 + x/6 = 7/2)
- 6(x / 3) = 2x
- 6(x/6) = x
- 6(7/2) = 3*7 = 21
Result
- 2x + x = 21
- 3x = 21
- 3x/3 = 21/3
- x = 7
Check
- 7/3 + 7/6 = 7/2
- 14/6 + 7/6 = ? 7/2
- 21/6 =? 7/2
- 21/6 = 3.5
- 7/2 = 3.5
Answer: x = 7
Answer:
y = 5x +4
Step-by-step explanation:
