Answer:

AQ = 20 units

Step-by-step explanation:

Comparing triangle AQR to ABC,

$\frac{AQ}{AB}$ = $\frac{QR}{BC}$

$\frac{4p}{8p}$ = $\frac{2p + 3}{6p-4}$

cross multiply and make p the subject of formula, we have:

8p (2p+3) = 4p(6p-4)

16 $p^{2}$ + 24p = 24 $p^{2}$ - 16p

24p + 16p = 24 $p^{2}$ - 16 $p^{2}$

40p = 8 $p^{2}$

divide through by 8p,

p = 5

Therefore, AQ = 4p

= 4 × 5

= 20

AQ = 20 units

Xan and Katie are twins. Xan weighs 66 6 6 pounds 99 9 9 ounces, and Katie weighs 88 8 8 pounds 11 1 1 ounce. What is the differ

gtnhenbr [62]

Answer:

264 ounces

Step-by-step explanation:

#Convert Xan weight into ounces:

$1lb= 16 \ oz\\\\66\ lb=66\times 16=1056 \ oz\\\\\therefore Xan's=1056 \ oz+ 99 \ oz=1155 \ oz$

Convert Katie's 88 pounds 11 ounce to ounces:

$1lb= 16 \ oz\\\\88\ lb=88\times 16=1056 \ oz\\\\\therefore Katie's=1408 \ oz+ 11 \ oz=1419\ oz$

The difference is calculated by subtracting Xan's from Katie's:

$=1419 \ oz-1155 \ oz\\\\=264\ oz$

Hence, the difference between the weights is 264 ounces
