x + 2y = 9
x + 3y = 13
____________________________________________________________
Solve for x in the first equation. Subtract 2y from both sides.
x = 9 - 2y
____________________________________________________________
Plug x into the second equation.
(9 - 2y) + 3y = 13
Combine like terms.
9 + y = 13
Subtract 9 from both sides.
y = 4
____________________________________________________________
Plug y back into the first equation.
x + 2(4) = 9
x + 8 = 9
Subtract 8 from both sides.
x = 1
____________________________________________________________
x = 1
y = 4
Let us assume the amount of baskets Joe scored = x baskets.
4 times of x is 4x.
4x+x = 5x.
Therefore, Peter scored = 5x.
Together they scored = 32 baskets.
Sum of Peter score and Joe score = 32.
x+5x = 32.
6x = 32.
Dividing both sides by 6, we get
x = 32/6
= 16/3.
x= 16/3.
<h3>Joe scored = 16/3 baskets.</h3><h3>Peter scored = 5 × 16/3 = 80/3 baskets.</h3>
Answer:
12.449899598
Step-by-step explanation:
You would use pythagoras thereom.
C^2=A^2+B^2
The hypotenuse is C (which is the longest side of the triangle - 18).
18×18=13×13+B^2
324=169+B^2
324-169=B^2
155=B^2
Square root B to get B on it's own which would be 12.449899598.
