Hello! I can help you!
12. Okay. 16 1/5 is 16.2 in decimal form. Let’s subtract both numbers. 19.8 - 16.2 = 3.6. Paloma is 3.6 seconds faster than Savannah in the 100m dash.
13. Two lengths that are within the given span of 0.08 and 0.4 are 0.22 and 0.17. 0.22 as a fraction in simplest form is 11/50 and 0.17 as a fraction in simplest form is 17/100.
Answer:
22?
Step-by-step explanation:
Just take 40 and subtract the 7 to get 33 and then 2 to get 31 and 9 to get 22.

Answer:
- Infinitely many solutions
Step-by-step explanation:
First, let's organize the equations of the lines into slope-intercept form.
- x + 4y = 1
- => 4y = -x + 1
- => y = -x/4 + 1/4
And,
- 2x + 8y = 2
- => 8y = -2x + 2
- => y = -2x/8 + 2/8
- => y = -x/4 + 1/4
Since both the graphs are the same, the two equations have infinitely many solutions.
Let the width of the rectangle be x
Then length =x-4
Area=x(x-4)=140
x²-4x=140
x²-4x-140=0
x²-14x+10x-140=0
x(x-14)+10(x-14)=0
(x-14)(x+10)=0
Therefore,length=14 cm and width=10 cm
