Answer:
17 for 1 point shots and 35 for two point shots.
Step-by-step explanation:
let the number of 1 point shots be x
let the number of 2 point shots be y
x + y = 52 (1)
x + 2y = 87 (2)
subtracting (1) from (2)
y = 35
from (1) x = 52 - y = 52 - 35 = 17
Hence number of 1 pointers = 17
number of 2 point shots = 35
checking; 17 + 35 =52 ; and 17+ 2*35 = 87
Answer:
21,800
Step-by-step explanation:
I'm assuming you meant 2.18 x 10^4
Since the exponent is positive, you will move the decimal point 4 spaces to the right.
Answer:
.188 pounds per day
Step-by-step explanation:
Given
- 35 pounds gained in 186 days
<u>Divide the amount of pounds gained by the total number of days</u>
35/186 = .188
<u>Answer</u>
Approximately .188 pounds per day.
Our system of equations is:
y = -3x + 9
y = -x - 5
To solve this system of equations, we are going to use substitution. This means that we are going to substitute the second equation into the first equation since both are already solved for y in terms of x.
y = -3x + 9
-x - 5 = -3x + 9
Now, we must simplify by moving all of the constant terms to one side of the equation and all of the variable terms to the other side.
-x - 5 = -3x + 9
2x - 5 = 9
2x = 14
Finally, to undo the multiplication between the coefficient 2 and the variable x, we must divide both sides by 2 to get the variable x alone.
x = 7
Next, we must substitute in this value we have solved for x into one of the original equations to solve for the other variable, y.
y = -3x + 9
y = -3(7) + 9
To simplify, we must multiply through the parentheses and combine like terms by addition.
y = -21 + 9
y = -12
Therefore, your final answer is x = 7 and y = -12, or as an ordered pair (7, -12).
Hope this helps!
Answer:
1. X=-3, Y=0
2. all real numbers
Step-by-step explanation:
1.
2x+x+3=-6
3x+3=-6
3x=-9
x=-3
y=-3+3
y=0
2.
6x-2(3x-6)=12
6x-6x+12=12
0=0
All real numbers
