Answer:
7.5 < x≤10.5
Step-by-step explanation:
14<2x−1≤20
Add 1 to all sides
14+1<2x−1+1≤20+1
15<2x≤21
Divide each side by 2
15/2 <2x/2 ≤21/2
7.5 < x≤10.5
Answer:
y = - 3x -11
Step-by-step explanation:
(x₁ , y₁) = (-2 , -5) & m = -3
y - y₁ = m (x - x₁)
y - [-5] = (-3)(x -[-2])
y + 5 = (-3)(x + 2)
y + 5 = -3x - 6
y = -3x - 6 - 5
y = - 3x -11
Answer:
83%
Step-by-step explanation:
No. of questions answered correctly = 166
Total no. of questions = 200
Percentage of questions answered correctly = (166/200)*100 = 83%
The ratio would need to be 1:1 in order to split the line in half. Think of it like having two cookies. If you split those cookies between you and your friend, then you get 1 and s/he gets the other. So the ratio of your cookie count to your friend's count is 1:1
With the ratio 1:2, you would have 1 cookie while your friend has 2 cookies. This is no longer a fair split. Things are not 50/50 anymore. You have 1/3 of the cookies while your friend has 2/3 of the cookies. Your friend would have twice as much.
So that applies to the segment lengths as well. The line segment would be split up into two parts A and B. Part A is the smaller segment that is half as long as part B. Or put another way, part B is twice as long as part A
Answer:
x = - 6
Step-by-step explanation:
Equation
1/3 * (-9x +12) = 22 Multiply both sides by 3
Solution
3 * 1/3(-9x + 12) = 22*3
- 9x + 12 = 66 Subtract 12 from both sides.
-9x = 66 - 12 Combine
-9x = 54 Divide by -9
x = 54/-9
x = - 6
