A+j=59 so j=59-a
and j=a-3
j=j so
59-a=a-3 subtract a from both sides
59-2a=-3 subtract 59 from both sides
-2a=-62 divide both sides by -2
a=31
n=a=31

Answer:
y = -3x - 8.3
Step-by-step explanation:
You need to rearrange 9x + 3y = -22 in the form y = mx+c.
9x+3y = -22
3y = -9x - 22
y = -3x - 7.3
As long as the gradient is the same, the lines will be parallel. So you can give any number to the intercept (in this case I gave 8.3) and you will have parallel equations.
Final answer : y = -3x - 8.3
Answer:
x = 0, 7
Step-by-step explanation:
Step 1: Write out equation
x² - 7x = 0
Step 2: Factor out <em>x</em>
x(x - 7) = 0
Step 3: Find roots
x = 0
x - 7 = 0
x = 7
Answer:
6.31 1/6
Step-by-step explanation:
6. For this problem, we know that 2 angles are congruent: the right angles and the angles closest to the "mirror." We know that those angles are congruent for mirrors reflect light to where it is congruent on both sides. Since we have two congruent angles, we can use AA Similarity to solve for the height of the hill. We can set up the proportion 6/34 = 5.5/x. We can cross multiply, which results in 6x = 187, and if we bring over the 6 so that x = 187/6, or 31 1/6.
