Answer:
look at explanation
Step-by-step explanation:
To solve all of these questions you just need to scale. While scaling you can divide or multiply.
1. (divide by 4 to get unit rate)
unit rate =
2. If it takes one hour to travel 40 miles, then we don't have to scale or anything. We know , the answer is...
"It'll only take one hour to travel 40 miles. This is correct because the unit rate is . "
3. Knowing that the constant speed of the plane is , we can scale then add half of the unit rate to get our answer.
x 3 = 800 x 3 = 2400
then add half of unit rate which is = 400
so, our answer is
4. <--- ( divided by 2) ( multiplied x 2.5) --->
To get an easier way to find the answer, if possible you can scale back farther than the 1 hour mark.
Elmer would take 2 and a half hours to ride 15 km.
5. The boys speed is . All we need to do is divide by 2. = 4
Answer:
b
Step-by-step explanation:
the graph gets translated 5 units above its parent graph of y = x
<span>2x+38=180 since all triangles add up to 180 and we have 38 as a degree we have to find the value of
2x=180-38
2x=142
x=142÷2
x=71</span>
The answer to the question is
3x+2=3x-2
