Answer: D
Step-by-step explanation:
so we know the probability of drawing a 9 is 25 percent or 1/4 because 9 is only one and doesn't repeat.
So the cards we drawn cards we drawn 2 times so multiply 1/4 times two.
1/4 * 2/1= 2/4 = 1/2
Jacob found 0.6 pears, I know this because 6 divided by 10 is 0.6.
Answer:
11. odd, 12. slope = 2 and the line rises.
Step-by-step explanation:
11. To determine if the function is odd, even, neither, you have to plug in -x in the function and simplify.If you end up with the exact same function that you started with (that is, if f (–x) = f (x), so all of the signs are the same), then the function is even. If you end up with the exact opposite of what you started with (that is, if f (–x) = –f (x), so all of the signs are switched), then the function is odd. In all other cases, the function is "neither even nor odd".
12. y2 - y1 / x2 - x1
1-9/-2-2 = 2
Answer: x = 3
Step-by-step explanation:
Note that this triangle has 3 congruent angles. Therefore, it is an equilateral triangle. So, the sides will also be congruent.
So it can be said that : 6x - 3 = 3x + 6
+3
6x = 3x +9
-3x
3x = 9
/3
x = 3
By replacing x with 3, we can prove that these expressions all equal 15.
6(3) -3 = 18 - 3 = 15 . 3(3) + 6 = 9 + 6 = 15 . 5(3) = 15
<h3>16 lollipops and 9 bags of chips are sold</h3>
<em><u>Solution:</u></em>
Let "x" be the number of lollipops sold
Let "y" be the number of bags of chips sold
Cost of 1 lollipop = $ 1.50
Cost of 1 bag of chip = $ 1.75
<em><u>Yesterday Lucy made $39.75 from selling a total of 25 lollipops and bags of chips</u></em>
Therefore,
x + y = 25
y = 25 - x -------- eqn 1
<em><u>Yesterday Lucy made $39.75</u></em>
Therefore,
number of lollipops sold x Cost of 1 lollipop + number of bags of chips sold x Cost of 1 bag of chip = 39.75
1.5x + 1.75y = 39.75 -------- eqn 2
<em><u>Substitute eqn 1 in eqn 2</u></em>
1.5x + 1.75(25 - x) = 39.75
1.5x + 43.75 - 1.75x = 39.75
0.25x = 4
<h3>x = 16</h3>
<em><u>Substitute x = 16 in eqn 1</u></em>
y = 25 - 16
<h3>y = 9</h3>
Thus 16 lollipops and 9 bags of chips are sold
