Answer:
$153
Step-by-step explanation:
You would multiply 90 and 0.70 to get 63. Then you add that to the original price, 90, and get 153.
15 ~ 3 - (14~2) just a note, this ~ means the division sign
Where is the question?? I'll be glad to answer in the comments once the question is given. Hope to hear from you!
Step 1: Simplify both sides of the equation.
3(x−3)+5=3x+1+4
(3)(x)+(3)(−3)+5=3x+1+4(Distribute)
3x+−9+5=3x+1+4
(3x)+(−9+5)=(3x)+(1+4)(Combine Like Terms)
3x+−4=3x+5
3x−4=3x+5
Step 2: Subtract 3x from both sides.
3x−4−3x=3x+5−3x
−4=5
Step 3: Add 4 to both sides.
−4+4=5+4
0=9
Answer:
Step-by-step explanation:
y = 3x + 2
6x – 2y = 10
Ryan’s answer:
I solved by adding the equations. The solution is .
y = 3x + 2 → 3x + y = 2
6x – 2y = 10 → 3x – y = 5
6x = 7
x =
6x – 2y = 10 → 6 – 2y = 10
7 – 2y = 10
–2y = –3
y = -
Jesse’s answer:
I used matrices. The solution is .
Mark’s answer:
I graphed the equations. The lines are parallel and do not intersect, so there is no solution.
