Let's solve ~

\qquad \sf  \dashrightarrow \: 10x + 30 = 90

[ according to given figure ]

\qquad \sf  \dashrightarrow \: 10x = 90 - 30

\qquad \sf  \dashrightarrow \: 10x = 60

\qquad \sf  \dashrightarrow \: x = 60 \div 10

\qquad \sf  \dashrightarrow \: x = 6 \degree

If f(x)=x+8 and g(x)=-4x-3 find (f+g)(x)
nydimaria [60]

Answer:

for this case we have the following functions:

f (x) = x + 8

g (x) = -4x - 3

Subtracting the functions we have:

(f - g) (x) = f (x) - g (x)

(f - g) (x) = (x + 8) - (-4x - 3)

Rewriting:

(f - g) (x) = x + 8 + 4x + 3

(f - g) (x) = 5x + 11

Answer:

D. (f - g) (x) = 5x + 11

I really need an answer pls I used all my points :’(
Mazyrski [523]

Answer:

266 tickets

Step-by-step explanation:

Ratio of adult tickets to child tickets is 4 : 3

So, if we think of these as "parts", there are 4 parts adult tickets and 3 parts child tickets.

In total there is:

4 + 3 = 7 parts

Now, given 152 adult tickets. If there are 4 parts of adult tickets, how much is each part worth?

152/4 = 38

Total amount of tickets is 7 of these "parts", so total number of tickets is:

38 * 7 = 266 tickets
