Solve the problem yourself first, to see if Pedro made any mistakes.
4/7 x 8/5
4x8 = 32
7x5 = 35
32/35 is the answer.
Pedro made his error in step 2, he cross multiplied instead of multiplying the numerators, and then the denominators.
well there is 7x4, 14x2, and 28x1 of course.
You would need to know the distance in between the points by using the distance formula ( y2-y1/x2-x2) Then add them together
Answer:
Step-by-step explanation:
27 - 1.5x ≤ 36
54 - 3x ≤ 72
54 - 72 ≤3x
-18 ≤ 3x
-6 ≤ x
x ≥ -6
