In part A, if a's value is 1 then b is 2 and so on so the first letter of your name will have a number, and for part b you tale 3 letters that make up a word and the number after also equals 20.
Answer:
<em>(-3/5, 29/5) </em>
Step-by-step explanation:
Given the simultaneous equation;
-3x+4y=25...... 1
y= -3x+4 ..... 2
We are to confirm if (-3, 4) is the solution to the equations;
Substitute equation 2 into 1;
From 1;
-3x+4y=25
-3x + 4(-3x+4) = 25
-3x -12x + 16 = 25
-15x = 25 - 16
-15x = 9
x = -9/15
x = -3/5
Substitute x = -3/5 into equation 2 to get y;
From 2;
y= -3x+4
y = -3(-3/5)+4
y = 9/5 + 4
Find the LCM
y = (9+20)/5
y = 29/5
<em>Hence the solution to the system of equation is (-3/5, 29/5) hereby falsifying Julie's solution.</em>
The answer to your question is C40
<span>According to the Pythagoras's theorem, The sum of the square of the hypotenuse is equal to the sum of the square of the other two sides.
</span><span>x^2 + x^2 = (29)^2 = 29 x 29 = 281
2x^2 = 841
x^2 = 841/2 = 420.5
x = sqrt(420.5) = 20.51 inches</span><span>
