8 4
- -
18 9
Step-by-step explanation:
sorry i dont know how to put a fraction but that is the answer because after the red coin is removed and the 3 blue coins are added there will be 9-1=8 red coins and 7+3=10 blue coins for a total of 8+10 coins the probability of then choosing a red coin is then the answer put up there tell me if that helped please!
Start by isolating the variable on one side by adding 43w^2 to both sides. The equation will read:
25w^2+5=0
<em>*Subtract 5 from both sides*</em>
25w^2=-5
<em>*Divide both sides by 25*</em>
w^2=-1/5
<em>*Take the square root of both sides*</em>
w=√(-1/5)
The square root of -1 is i. The square root of 5 remains √5
The answer is i/√5.
Hope this helps!!
Answer:
Let the cost of orange be X and cost of cherry be y
3x + 9y = 78
8x + 4y = 58
Solving equation using elimination method
multiplying eq 1 with 8 and eq 2 with 3
8(3x + 9y ) = 78(8)
3( 8x + 4y) = 3(58)
24x + 72 y = 624
24x + 12y = 174
subtracting,
60 y = 450
y = 7.5
3x + 9(7.5) = 78
3x + 67.5 = 78
3x = 78 - 67.5
3x = 10.5
x = 3.5
<h2>Box of orange = $3.5 </h2><h2>Box of cherry = $7.5</h2>
