Answer:
s = 16.2 units
Step-by-step explanation:
s^2 = 15^2 + 6^2 (6 is 1/2 of 12)
s^2 = 225 + 36
s^2 = 261
s = 16.16
Answer: Yes
Explanation: a statement that the values of two mathematical expressions are equal (indicated by the sign =).
Two values (6 and 3) are being brought together for another value represented by the = symbol making this an equation
First, fifth, and sixth are correct!
If y is substitute into either of the original equation. The solution as an ordered pair are: x=-2; y=3.
<h3>The solution as an ordered pair</h3>
x + 3y= 7 equation 1
x+2y=4 equation 2
Solving for y
x+3y-(x+2y)=7-4
x+3y-z-2y=7-4
3y-2y=7-4
y=7-4
y=3
Substitute y=3 into equation 2
x+2y=4
x+2×3=4
x+6=4
Collect like terms
x=4-6
x=-2
Therefore the solution as an ordered pair are: x=-2; y=3.
