Go to the third pic for your answer. I got problem 4 wrong but it shows the correct answer.
3[x+3(4x-5)]=15x-24; x+12x-15=5x-8 (divide both sides by 3); 8x=7 (move all the x's to one side), x=7/8
Answer:
88 rolls of 2.
Step-by-step explanation:
By proportion that would be 220 * 20/50
= 220 * 0.4
= 88.
It should be d. , Because if you take the equation 3x+y=9, and make it slope intercept form, it would be y= -3x+9. -3 is the slope, and 9 is the y intercept. D is the answer.
Can you please tell me your question?
