Answer: Rewrite equations:
3x=y;x−2y=10
Step: Solve3x=yfor y:
3x=y
3x+−y=y+−y(Add -y to both sides)
3x−y=0
3x−y+−3x=0+−3x(Add -3x to both sides)
−y=−3x
−y
−1
=
−3x
−1
(Divide both sides by -1)
y=3x
Step: Substitute3xforyinx−2y=10:
x−2y=10
x−23x=10
−5x=10(Simplify both sides of the equation)
−5x
−5
=
10
−5
(Divide both sides by -5)
x=−2
Step: Substitute−2forxiny=3x:
y=3x
y=(3)(−2)
y=−6(Simplify both sides of the equation)

Answer:
5
Step-by-step explanation:
The slope between (4,3) (3,-2) can be found using the following formula
m = (y2-y1)/(x2-x1)
=(-2-3)/(3-4)
= (-5)/(-1)
=5
Answer:
Step 1: Take the first digit of the dividend from the left. Check if this digit is greater than or equal to the divisor.
Step 2: Then divide it by the divisor and write the answer on top as the quotient.
Step 3: Subtract the result from the digit and write the difference below.
Step 4: Bring down the next digit of the dividend (if present).
Step 5: Repeat the same process.

Answer:
B. 12.25 cm^2
Step-by-step explanation:
Formula for area of trapezoid is:
A = 
* h <u>where a and b is the bases and h is the height</u>
A = 
* 3.5 <u>We plug in the numbers</u>
A = 12.25 cm^2
