30 is 120% of what number? show ur work
Yanka [14]

Answer:

30 is 120% of 25

Step-by-step explanation:

30 = 120% of y

\frac{120}{100} × y = 30

After multiplying both sides by 100 and dividing both sides by 120, we have

y = 30 × \frac{100}{120}

y = 25

Here are two points from line AB: A (9,-2) B(1, 14) Here are two points from line CD: C (6.-10) D (8,-14) Are these lines parall
valentinak56 [21]

Step-by-step explanation:

slope of AB = y2 -y1/x2 -x1 =14 -(-2)/1-9

= 14 +2 /1 -9

= 16/-8

= -2

slope of CD = -14 -(-10)/8 -6 = -14 +10 /2

-4/2 = -2

since slope of AB = CD

(The lines are parallel to each other)
