Answer:
Number of Starbursts= 66
Step-by-step explanation:
Method:
The first step in working out the number of Starbursts in the bowl is to add the the ratios of 3 and 4, this gives you 7.
The next step is to divide the total number of sweets which is 154 by the value of 7, this gives you 22. This is because we are trying to find out the value of one in the ratio.
The final step would be to work out the number of Starbursts in the bowl. This can be done by multiplying 22 by the ratio for Starbursts which is 3, this gives you 66. This means that out of 154 sweets 66 of them were starbursts.
Set by step:
1) Add 3 and 4.
2) Divide 154 by 7.

3) Multiply 22 by 3.

Y^2x -2y^x +1 , rewrite using the formula for standard form
To find the percentage of 12/30 you simply have to divide 12 by 30, and then multiply it by 100
(12/30)100
(0.4)100
40%

when you make a small number scientific notation, it will be negative. there has to be one number in the ones place for it to be written correctly. hope this helps!
4x-2
+2
so that leaves 4x
divide by four
x = 1
