Answer:

x=12

y=20

Step-by-step explanation:

<u>the</u><u> two</u><u> triangles</u><u> are</u><u> congruent</u><u> </u>

according to the question

x+18=6x-42

6x-x=18+42

5x=60

x=12

if two triangles are congruent the included Angeles are equal

so

y+22=3y-18

3y-y=22+18

2y=40

y=20

Calculus AB

Assuming you mean
\lim_{x \to 4} \frac{\sqrt{x+5}-3}{4-x}

that means as x approaches 4

if we sub 0 for x we get
0/0
and intermitent form
use l'hopital's rule

so
take the derivitive of the top and bottom seperatly
l'hopitals rule is something like
if \lim_{x \to n} \frac{f(x)}{g(x)} results in 0/0 or -∞/∞ or∞/∞ then keep doing it until f(n)/g(n) gives a form that isn't intermitent

so

take derivitive of top and bottom
\dfrac{\frac{1}{2\sqrt{x+5}}}{-1}
now, if we subsitute 4 for x we get
\dfrac{\frac{1}{2\sqrt{4+5}}}{-1}=

\dfrac{\frac{1}{2\sqrt{9}}}{-1}=

\dfrac{\frac{1}{2(3)}}{-1}=

\dfrac{\frac{1}{6}}{-1}=

\dfrac{1}{-6}=\dfrac{-1}{6}

Help me with this please asap​
Sloan [31]

Answer:

See below

Step-by-step explanation:

32.  w + 5 = -20

       w = -20 - 5

       w = - 25

33.  x - 17 = -32

       x = -32 + 17

       x =  - 15

34.  t + 7.2 = 1.65

       t = 1.65 - 7.2

       t = - 5.55

35.  -0.4 = g - 4.9

       g = - 0.4 + 4.9

       g = 4.5

36.  y - 2/5 = 1 3/5

       y = 1  3/5  +   2/5

       y =  1   5/5  or   2

37.  -5 1/6 = 2 1/3 + p

       p =  - 5 1/6  -  2  1/3  convert 1/3 to x/6 for a common denominator

1/3 converts to 2/6

        p =  -5  1/6  -  2  2/6

        p =  - 7   3/6    or   - 7  1/2

38.  You were given that

Simone =  $65.35 + Dan

Simone =  Carly - 37.50

Carly = 127.75

So Simone = 127.75 - 37.50  =  90.25

Simone = 65.35 + Dan   or Dan = Simone - 65.35

Dan = 90.25 - 65.35 = 24.90

Jan has 37.50 tickets to a concert concert 5.25 each how many tickets can Jan buy
alexandr1967 [171]
Number of tickets= X
To find the number of tickets, divide the money Jan has with the cost of each ticket.
So,
X =37.50/ 5.25=7.14

But since she can't buy part of a ticket, Jan can buy 7 tickets
