Answer:
y=x-2
Step-by-step explanation:
if x: 5, x-2=3
y=x-2
therefore:
y=3
x=5
Think of it as a triangle. 20 is the height, 5 is the side. Use the Pythagorean Theorem to find the diagonal distance. 20 squared, or 400, plus 5 squared, or 25, is 425. Now square root that. It's around 20.6. However, they might just ne asking an addition question, since you can't go through solid blocks...
5x + 3 = 3x + 11
• first put all the x-values on one side and the rest on the other
Remember: when the number moves to the other side of the equal sign the sign (+ OR - switches. For ex: the 3 on the left becomes negative when moved to the right side of the equal sign)
5x - 3x = 11 - 3
• subtract left and right sides separately
2x = 8
• divide both sides by 2 to solve for x
2x/2 = 8/2
x = 4 (final answer)
Answer: d + q <u>></u> 17
Step-by-step explanation:
Answer:
the cost for each drink = $2.54
Step-by-step explanation:
The statement formed a simultaneous equation :
3x + 6y = $21.12
4x + 9y = $30.41
solving simultaneously,you have that ; x = 2.54, y = 2.25
