Answer:
The answer is 20 points
Step-by-step explanation:
If the points is based on 100 by rating, and your confidence level of 'I think I know it' places you on the initial risk of 80 points as suggested, which eventually places you on the wrong side, you will be left with the following:
Total rating point of 100 minus initial risking points of 80. This leaves you with a second chance points of just 20.
Answer:
(5, 2)
Step-by-step explanation:
Given the following system of equations;
2x - 2y = 6 ......equation 1.
4x + 4y = 28 ......equation 2.
To get an equivalent equation, we would multiply eqn 1 by 2;
2 * (2x - 2y = 6) = 4x - 4y = 12
The new equivalent system of equations are;
4x - 4y = 12
4x + 4y = 28
Adding the equivalent system of equations, we have;
(4x + 4x) + (-4y + 4y) = (12 + 28)
8x + 0 = 40
8x = 40
x = 40/8
<em>x = 5</em>
Next, we would find the value of y;
2x - 2y = 6
Substituting the value of x, we have;
2(5) - 2y = 6
10 - 2y = 6
Rearranging the equation (collecting like terms), we have;
2y = 10 - 6
2y = 4
y = 4/2
<em>y = 2</em>
<em>Therefore, the solutions to the new system of equations are 5 and 2.</em>
<u>Check:</u>
2x - 2y = 6
Substituting the values, we have;
2(5) - 2(2) = 6
10 - 4 = 6
6 = 6
Answer:
He made 5 2-pointers and 4 3-pointers
Step-by-step explanation:
Let x = number of 2-pointers he scored.
Let y = number of 3 pointers he scored.
The total number of shots he made is x + y, and it it equals 9.
The first equation is
x + y = 9
The total number of points he scored on 2-pointers is 2x. The total number of points he scored on 3-pointers is 3y. The total number of points he scored with 2-pointers and 3-pointers is 2x + 3y. It equals 22.
The second equation is
2x + 3y = 22
We have a system of 2 equations.
x + y = 9
2x + 3y = 22
We will use the substitution method.
Solve the first equation for x.
x = 9 - y
Now substitute 9 - y in for x in the second equation.
2x + 3y = 22
2(9 - y) + 3y = 22
18 - 2y + 3y = 22
y + 18 = 22
y = 4
Now we substitute 4 for y in the first equation and solve for x.
x + y = 9
x + 4 = 9
x = 5
Answer: He made 5 2-pointers and 4 3-pointers
Check:
5 2-pointers and 4 3-popinters are a total of 9 shots, so the number of shots is correct.
Now we check the number of points.
5 * 2 + 4 * 3 = 10 + 12 = 22
22 points is the correct total.
Our answer is correct.
The answer is C I think try putting that one ok I tried to help so yeah um have a great day
