so counting 7 spaces from the number one should land you at 1.7
(the second red dot from the left)
hope i was able to help!
For this case we must find the value of "x" of the following expression:

Multiplying by 2 on both sides of the equation:

Subtracting 8x from both sides of the equation:

Adding 16 to both sides:

Dividing between -2 on both sides:

Answer:

9cm
Imagine there are 2 triangles solve for one 3*3=9\2=4.5
Then add
4.5+4.5=9
Answer:
Speed of first plane is 350 miles per hour
Speed of second plane is 100 miles per hour
Step-by-step explanation:
Let the speed of the second plane be X
Then the speed of the first plane will be 3.5 X
Distance travelled by first plane is 9.5 *X
Distance travelled by second plane is 9.5 * 3.5 X
Difference of distance between the two plane is
miles per hour
Speed of first plane is 3.5 *100 = 350 miles per hour
Speed of second plane is 100 miles per hour
