Answer:
22
Step-by-step explanation:
2x -6 = 38
Add 6 to each side
2x-6+6 = 38+6
2x + 44
Divide each side by 2
2x/2 = 44/2
x = 22
Answer: 26 4/5 miles pee gallon
Step-by-step explanation:
From the question, we are informed that Jack drove 33 1/2 miles and that he used 1 1/4 gallons of gasoline. The unit rate for miles per gallon will be calculated by dividing 33 1/2 by 1 1/4. This will be:
= 33 1/2 ÷ 1 1/4
= 26 4/5 miles per gallon
Answer:

Answer:
<em></em><em></em>
Step-by-step explanation:
Given system of equations are
2x-6y-2z = 1
3y - 2z = -5
2y + 2z = -3
given
2 x - 6 y - 2 z = 1
0 x + 3 y - 2z = -5
0 x +2y + 2 z = - 3
<em>The Matrix form of the given system of equations </em>
<em>A X = B</em>
