Answer:q=-6
Step-by-step explanation:
If the solution of the system is {(x,y) : x-3y=4}, then both equation should have proportional coefficients:
[tex]1/2=-3/q=4/8[/tex]
Solve it:
1/2 = -3/q
q=-3*2
q=-6
Check whether q=-6 is correct answer, substituting this value into the first ratio:
[tex]1/2=-3/-6=4/8[/tex]
q=-6

Answer:
Q = 2Step-by-step explanation:
If the solution to the system is the first equation only, then both equations should be same:
x - 3y = 4Qx - 6y = 8Double the first equation, then both of coefficients of y and constant will be equal:
2x - 6y = 8Qx - 6y = 8Comparing we get Q = 2

C. -8x2 + 34x - 35
D. -8x2 + 6x - 35
5x+4x-6x=24 what is the answer
Answer:
8
Step-by-step explanation:
First, solve the left side by adding/subtracting all the x's. 5x + 4x - 6x = (5+4-6)x = (9-6)x = 3x
Then if 3x=24, x must be 8.

The value of measure of angle ∠ A is,
⇒ ∠ A = 50°
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
In triangle ABC,
∠ B = 100°
∠ C = 30°
Since, The sum of all angles of a triangle are 180 degree
Now, We can formulate;
⇒ ∠A + ∠B + ∠C = 180°
⇒ ∠A + 100° + 30° = 180°
⇒ ∠A + 130° = 180°
⇒ ∠A = 180° - 130°
⇒ ∠A = 50°
Thus, The value of measure of angle ∠ A is,
⇒ ∠ A = 50°

A car averages 28.5 miles per gallon of gasoline. How many liters of gasoline will be needed for a trip of 415 km? Some conversion factors that may be helpful are the following:
Answer:
34.22 liters
Step-by-step explanation:
Step one:
Given data
A car averages 28.5 miles per gallon of gasoline
How many liters of gasoline will be needed for a trip of 415 km
let us convert 415km to miles first
1 km is 0.621371 miles
415km is x miles
cross multiply we have
x= 415*0.621371
x=257.86 miles
Step two:
if 1 gallon of gasoline will cover 28.5 miles
the x gallons will cover 257.86 miles
cross multiply we have
28.5x= 257.86
divide both sides by 28.5
x= 257.86/28.5
x=9.04 gallons
Step three:
let us convert gallons to liters
1 gallon is 3.78541 liters
9.04 gallons will be x liters
cross multiply we have
x=9.04*3.78541
x= 34.22 liters
