2.4=-5y+14.9
We move all terms to the left:
2.4-(-5y+14.9)=0
We get rid of parentheses
5y-14.9+2.4=0
We add all the numbers together, and all the variables
5y-12.5=0
We move all terms containing y to the left, all other terms to the right
5y=12.5
y=12.5/5
y=2+2.5/5
Y=2.5
Answer:
5,652,000
Step-by-step explanation:
1. Simplify 1/3 * 3.14
you'll end up with 3.14/3
2. Divide 3.14 by 3
this will give you 1.046
3. Raise 150 to the power of 2.
you now have 22,500
your equation is now: 1.046 * 22,500 * 240
4. Multiply 1.046 by 22,500
your equation is now 23,500 * 240
5. Multiply 23,500 by 240
your answer is 5,652,000
Step-by-step explanation:
So first you want to multiply the percentage of the yellow balls by three to get the amount of "300%" which is 300 balls. Munising 100 by 40, you get 60% is white. So multiply that by three also. So for Yellow, you have 120 balls, and for white, you have 180. So you take 120 and take 20% of it, and it would give us 24. You take the 180, and that one gives us 144. So if you add 144 and 24, Sally's team found 168 balls out of 300.
hope this helps
Answer:
0.25 or 1/4
Step-by-step explanation:
3 1/2 x 1/14 = 0.25
Answer:
∠1 = 23°
Step-by-step explanation:
∠WXZ = ∠WXY + ∠YXZ
Note that ∠2 = 4∠1 ( angle 2 is 4 times angle 1 )
Hence
4∠1 + ∠1 = 115
5∠1 = 115 ( divide both sides by 5 )
∠1 = 23°
