Answer:
Angle1:12
Angle2:168
Step-by-step explanation:
Angle 1+angle 2=180
X-9+8x=180
9x=189
x=21
angle1=21-9=12
Angle2=180-12=168
Answer:
It'd be C?
Step-by-step explanation:
Well, if you turn 5/2 into a mixed number, it will be 2 1/2, and if you add 2 1/2 to 3, it would be 5 1/2, and C is the only one that shows it. Not only that, you could probably find out with common sense, because there is no subtracting in this problem, but every other answer besides C is subtracting.
Hope this helps
Bit late though lol
Answer:
36.4%
Step-by-step explanation:
You know the most about Kim and Molly, so you should start with them.
Let kim's share = x
Therefore Molly's share = x + 105
Ratio
Kim is to Molly as 2 is 5
2/5 = x / (x + 105)
Solution
Cross multiply
2(x + 105) = 5x Remove the brackets.
2x + 2*105 = 5x Consolidate.
2x + 210 = 5x Subtract 2x from both sides
2x - 2x + 210 = 5x - 2x Reduce like terms.
210 = 3x Divide by 3
210/3 = x
70 = x
Laura's Share.
Kim = x = 70
Molly = x + 105 = 70 + 105 = 175
Kim + Molly + Laura = 385
70 + 175 + Laura = 385 Combine the left side
245 + Laura = 385 Subtract 245 from both sides
Laura = 385 - 245 Combine the right. (Subtract)
Laura = 140
Laura's %
Laura's % = (140 / 385) * 100 = 36.4 to 3 places.
I’m assuming you meant -2x^2 so It would be shifted to the left 3 it would be compressed from having 2 to 1.
Answer:
Yes, it is true that 1.555 <em>is </em>a rational number.
