What is equivalent to 6/9

If you want to find equivalent fractions to you can multiply the numerator and denominator by the same number.  You don't change the value of a fraction if you multiply its top and bottom numbers by the same number because you are just multiplying by 1.

Some equivalent fractions of 6/9 are:
2/3 = 4/6 = 6/9 = 8/12 = 10/15 = 12/18 = 14/21 = 16/24 = 18/27 = 20/30 = 22/33 = 24/36 = 26/39 = 28/42 = 30/45 = 32/48 = 34/51 = 36/54 = 38/57 = 40/60

A 32-meter antenna mast is stabilized by a 40-meter guy wire. How far from the base of the mast is the guy wire secured to the ground? A) 24
B) 6
C) 16
D) 8

To solve this, use the Pythagorean Theorem.
a^2 + b^2 = c^2 since it forms a right triangle
32^2 + b^2 = 40^2
1024 + b^2 = 1600
b^2 = 576
b = 24
so the correct answer would be A

Marina drove 288 miles in the same amount of time it took Jaime to drive 312 miles. If Jaime drove 6 miles per hour faster than Marina, at which speeds were Jaime and Marina traveling?

Let X = Marinas speed in MPH

Let T = Time

T=288/X
312=(X+6)T
312=(X+6)(288/X)
312=288X/X+1728/X
312=288+1728/X
312-288=1728/X
24=1728/X
24X=1728

X=1728/24
X=72 MPH  FOR MARINA

72+6=78 MPH FOR JAMIE

−4x+3y=−2
y=x−1
​ i need x and y

Rewrite equations:

y=x−1;−4x+3y=−2

Step: Solvey=x−1for y:

y=x−1

Step: Substitutex−1foryin−4x+3y=−2:

−4x+3y=−2

−4x+3(x−1)=−2

−x−3=−2(Simplify both sides of the equation)

−x=1

(Divide both sides by -1)

x=−1

Step: Substitute−1forxiny=x−1:

y=x−1

y=−1−1

y=−2(Simplify both sides of the equation)

x=−1 and y=−2

Which of the following points lies on the circle whose center is at the origin and whose radius is 13? (-5, 12) (, ) (6, -7)

The equation of a circle is defined by (x – h)² + (y – k)² = r² with the center being at (h, k) and with radius r. So for this circle with center at (0, 0) and r = 13 the equation is x² + y² = 169.
Then we plug in the ordered pairs:
(-5, 12)
(-5)² + (12)² = 169
25 + 144 = 169 is true.

The answer is (-5, 12). Hope that helps.
