Answer:
1/6
Step-by-step explanation:
We can make a Punnett square to find number of favourable outcome
so
cube1
+
cube2 1 2 3 4 5 6
1 2 3 4 5 6 7
2 3 4 5 6 7 8
3 4 5 6 7 8 9
4 5 6 7 8 9 10
5 6 7 8 9 10 11
6 7 8 9 10 11 12
The probability of rolling doubles given that the sum is 6
<h3> favourable outcome / number of outcome</h3>
6 / 36
1 / 6
Answer:
they have to pay for school supplies
Step-by-step explanation:
9. The slope for this one is 21 bc y1-y2/x1-x2 is the slope formula and this can be used between any two points (I used the first two) -30-(-54)/ 7-11 which is -84/-4= 21
10. Rate of change is the same thing as slope so 4.5-5/18-20 which is -0.5/-2 which means the rate of change is 2.5
11. 23-39/1-3 which is -16/-2 which means the rate of change is 8
12. 5/4 is 1.25 so the sports drink costs 1.25$ each
Hope this helped :)
Solution
For this case we can do the following:
And then if we multiply we got:
Answer/Step-by-step explanation:
3. By substitution method, let's substitute 
for y in the first equation.
Thus,
Solve for x
Add 4 to both sides
Multiply both sides by 3
Divide both sides by 5
Now, substitute 3 for x in the equation.
The solution of the equation is x = 3, y = -2
4. Solving by elimination, let's try to eliminate the x-variable by adding both equation together.
=> 
Divide both sides by -3 to solve for y
Substitute -5 for y in the first equation to find x
Subtract 10 from both sides
Divide both sides by 3
The solution is
