<u>14 packs of pencils</u> will be needed. Every 2 children use a pack and 28/2=14. Of course there are other ways to solve it too.
Answer: X=3
Explanation=
2•5x = 10x
2•9= 18
48-18=30
10x=30
Divide each side by 10
x=3
Answer:
Time travelled each day = 8 hours
Step-by-step explanation:
total distance of 2-day trip = 880 miles
half the distance each day = 880 ÷ 2 = 440 miles
velocity travelled each day = 55 miles per hour
time travelled each day = ???
velocity = (distance trvaelled) ÷ (Time)
55 = 440 ÷ Time
∴ Time travelled each day = 8 hours
Basically every time the input value is increased the output value is decreased an equal amount. Isn't the table the input increases from -1 to 1, which is an increase of two and the output decreases from 2 to 0, which is a decrease of 2.
Slope is 1
y intercept is also 1
