You can first convert everything to ounces and then subtract, when you get your answer convert it back to lbs.
*16 oz = 1 lb

12 lbs 5 oz = 197 oz
7lbs 10 oz = 94 oz

197 - 94 = 103

103/16
= 4 lbs and 7 oz

hope this helps :)

Hallie bikes 1 5/8 km before lunch 6 1/4 km How much farther does hallies bike after lunch than before lunch? Express your answe

kondaur [170]

Distance biked before lunch = 1 $\frac{5}{8}$ km (the number is written in mixed fraction)

⇒ Distance biked before lunch = $\frac{13}{8}$

Distance biked after lunch = 6 $\frac{1}{4}$ km (the number is written in mixed fraction)

⇒ Distance biked after lunch = $\frac{25}{4}$

We need to determine how much farther does Hallie bike after lunch than before lunch

Extra distance biked after lunch vs. before lunch = $\frac{25}{4}$ - $\frac{13}{8}$

⇒ Extra distance biked after lunch vs. before lunch = $\frac{50-13}{8}$

⇒ Extra distance biked after lunch vs. before lunch = $\frac{37}{8}$

⇒ Extra distance biked after lunch vs. before lunch = 4 $\frac{5}{8}$ (in mixed fraction)

Hence, Hallie biked 4 $\frac{5}{8}$ km extra after lunch vs. before lunch.

Serggg [28]

Answer:

x^2 -10x+25

Step-by-step explanation:

(x − 5)^2

(x-5)(x-5)

FOIL

first x*x = x^2

Outer -5 *x = -5x

inner -5*x = -5x

last -5*-5 =25

Add them together x^2 -5x-5x+25

Combine like terms x^2 -10x+25
