The answer is X = 5, and Y = -10 I hope this helps!! Please mark me brainliest
To convert a mixed number into an improper fraction<span>, multiply the whole number by the denominator and add it to the numerator. This becomes the numerator of the </span><span>improper fraction, so 3 x 2 = 6 + 5 = 11 so, your answer should be 11/2</span>
Base angles.
They are congruent.
There are 5280 feet in a mile. Knowing this, we can make the conversion from 2640 feet per hours to miles per hour:
(2640/5280)/1 hour = 0.5 miles / hour

Answer:
Step-by-step explanation:
salut :
en utilisant le theorem de Pythagore on obtient :
AC²= AB² + BC²
(a+5)² = 7²+a²
a²+10a+25 = 49+a²
10a+25 =49
10a =24
donc : a = 24/10 = 12/5 = 2.4 unit
