Answer:
d
Step-by-step explanation:
multiply the left side by 3 on the top and bottom to get 12x/15
then multiply the right side by 5 on the top and bottom to get 10x/15
then subtract 12x/15 and 10x/15 to get 2x/15
(1/2, -1/2) I went to Google and clicked the first link that popped up
1st answer: x= -7/2 -5/4y + 1/2z
2nd answer: x= 6 + 1/7y -2/7z
3rd answer: x= 28/3 -1/3y -4/3z
Steps
4x + 5y -2z = -14
Move variables to the right
4x = -14 -5y +2z
Divide both sides by 4
X= -7/2 -5/4y +1/2z
Answer
X= -7/2 -5/4y +1/2z
7x -y +2z =42
Move variables to the right
7x = 42 +y -2z
Divide both sides by 7
X= 6 + 1/7y -2/7z
Answer
X= 6 + 1/7y -2/7z
3x +y +4z = 28
Move variables to the right
3x =28 -y -4z
Divide both sides by 3
X= 28/3 -1/3y -4/3z
Answer
X= 28/3 -1/3y -4/3z
Answer:
child tickets - 47
adult tickets - 94
Explanation:
since the number of adult tickets sold is twice that of the number of child tickets sold, we can divide 141 into three parts to find the number of child tickets sold.
141 ÷ 3 = <u>47</u> (number of child tickets sold)
we can now multiply this by two to find the number of adult tickets sold.
47 × 2 = <u>94</u>
i hope this helps! :D
