Hope this helps I had the same problem. That’s what I got.
Answer:
7.23km/h
Step-by-step explanation:
Speed = distance/time
Given
distance = 6.36km and
Time = 53minutes
Convert 53minutes to hour.
60 minutes = 1 hour
53 minutes = x hour
Cross multiply
X hour x 60 = 53
Xhour = 53/60
X = 0.88 hour
Therefore
Speed = 6.36km /0.88hr
= 7.23km/h
For the Swiss cheese he sold 3 pounds of them and for the Cheddar cheese he sold 4 of them. When you multiply them together you get 24 for them both. 24+24=48. That's how you get your answer.
Answer:
(-2,-2)
Step-by-step explanation:
Step: Substitute 3x+4 for y in y=−x−4:
y=−x−4
3x+4=−x−4
3x+4+x=−x−4+x (Add x to both sides)
4x+4=−4
4x+4+−4=−4+−4 (Add -4 to both sides)
4x=−8
4x/4=−8/4(Divide both sides by 4)
x=−2
Step: Substitute −2 for x in y=3x+4:
y=3x+4
y=(3)(−2)+4
y=−2(Simplify both sides of the equation)
