Answer:
x = 4.5
Step-by-step explanation:
there's definitely other ways to solve this, but I used a proportion.

Then you can make this equation:
14x = 3.5 * 18
I solved for it and got 4.5 .
Divide 7 into 5 to find each penny value.
7/5 = 1.4
Thus, 1 penny is equal to 1.4 mm
100/1.4 = 71.43
Therefore 71.43 pennies is equal to 100mm.
The sentence that is true should have something to do with that 10 multiplied by any number is the number being multiplied by 10 with a zero at the end.
All numbers greater than 0 and smaller than 10 multiplied by 10 and their products are
1×10=10
2×10=20
3×10=30
4×10=40
5×10=50
6×10=60
7×10=70
8×10=80
9×10=90
I hope this helps
Answer:
The constant of proportionality is 1.5 and the value of q is 9.
Step-by-step explanation:
Assume Hours as 'x' and Miles walked = 'y'
Constant of proportionality means the same value of
is maintained throughout.
So, note that
= 1.5
This means that
should also equal 1.5.

= 9.
Therefore, the value of 'q' is 9.
