Step 1.) Multiply both sides of the equation by -6
step 2.) Sum the equations vertically to eliminate at least one variable
step 3.) Divide both sides of the equation by
step 4.) Substitute the given value of into the equation x - 2y = 10
step 5.) Solve the equation for x
step 6.) The possible solution of the system is the ordered pair (x , y)
step 7.) Check if the given ordered pair is the solution of the system of equations
step 8.) Simplify the equalities
step 9.) Since all of the equalities are true, the ordered pair is the solution of the system
So your answer would end up being (40/13 , -45/13) !! Hope that helps you out :D !!

Answer:
Maria is 10, Floyd is 8, and Karen is 5.
Step-by-step explanation:
Having said that Maria's age was the smallest two-digit number, that's ten. (10). If Floyd is 2 years younger then 10-2=8. Karen is 3 years younger, so she would be 8-3=5.
Answer:
none of the tables shown
Step-by-step explanation:
Inverse variation is
xy = k where k is the constant
xy = 4
in the top table
-2*2 = -4 so it cannot be the first table
In the middle table
-2 * -8 = 16 so it is not the middle table
In the bottom table
-2 *4 = -8 so it is not the bottom table
There must be a table not shown
Answer:
B 7feet
Step-by-step explanation:
Side a = 24
Side b = 25
Side c = 7
Angle ∠A = 73.74° = 73°44'23" = 1.287 rad
Angle ∠B = 90° = 1.5708 rad = π/2
Angle ∠C = 16.26° = 16°15'37" = 0.28379 rad
C=16.26°B=90°A=73.74°b=25a=24c=7
Area = 84
Perimeter p = 56
Semiperimeter s = 28
Height ha = 7
Height hb = 6.72
Height hc = 24
