A small private airplane traveled 140 miles in the same amount of time it took a helicopter to travel 95 miles. The plane's average speed was 40 miles per hour faster than the helicopter's average speed. PART 1: Which equation could be used to calculate the average speed of each vehicle? A. 140 95 B. 95 x + 40 Y Y + 40 C. 140x = 95x + 40 D. 40. 235​

step-by-step explanation:

b and c

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.

so the rectangle is 80cm (area)

now to find the area of a triangle.

base times height.

4 times 8.

your answer is 96cm.

hope this .
