Answer:
Tara's current expression finds how much the school will be keeping. 50 x 2/5 (also written as 50 x 0.4) totals out as 20. $20 is 2/5 of $50. The expression that Tara SHOULD have written to find how much goes to the candle company would be 50 x 3/5 (also written as 50 x 0.6), as this adds up to 30. $30 is 3/5 of $50.
Step-by-step explanation:
50/5 = 10 which means that 1/5 of 50 = 10.
2/5 of 50 ($20) is kept by the school. This is what Tara's expression finds. This means that $30 is sent to the candle company, and can be found with the expression 50 x 3/5.
The decimals are created by dividing the numerator of the fraction by the denominator (I find it easier to do math with decimals).
He is correct and incorrect. 2 and 4 can create factors but they can also be factors of other numbers. So 8 can be a factor of bigger whole numbers and can also have it own smaller factors.
Simple,
The Y inctercept.
To find the Y intercept we know x=0 because the graph crosses the y axis when x axis is 0 so.
Y=4x-2
Y=4(0)-2
Y=-2 y interecpt is -2
The x intercept.
To find the X intercept we know y=0 because the graph crosses the x axis when y axis is 0 so.
Y=4x-2
0=4x-2
2=4x
2/4 = x x intercept is 2/4 or 0.5
It might be the first one or the second one. i said MIGHT!!
