Tickets to the movies cost $12 for adults and $8 for children. A group of 14 people went to the movies, and the tickets cost $136. The system of equations models this situation, where x is the number of adults and y is the number of children.x+y=14
12x+8y=136
How many adults and how many children were in the group?
A.
9 adults and 5 children

B.
6 adults and 8 children

C.
4 adults and 10 children

D.
8 adults and 6 children

Answers

-12*/x+y=14
12x+8y=136

-12x-12y=-168
12x+8y=136
+--------------------
-4y= -32

y=8

x+y=14

8+y=14,

y=6

This question answer  is 6 adults and 8 children

AC = 4, AE = 7, AD = 10, what is the length of AB?


PLZ HELP

Answers

The above answer is not correct! The correct way to solve this is to look at the ratio of the sides as these are similar triangles. We are told that AC = 4 and AE = 7. That means that the side AC has been multiplied by 7/4 in order to become the length AE. Because these are similar trianges, all the sides must be multiplied by the same amount - therefore the side AD is equal to the length of AB multiplied by 7/4. Because we are given the side AD and need to find AB, we simply run the process in reverse like so:
If AD = 7/4 x AB:
AB = 4/7 x AD
AB = 4/7 x 10
AB = 40/7 (5.71 as a decimal)
Hope I helped :))

Answer:

The length of AB is 1 3/7 .

Solve for ggg.3 =\dfrac g{-4}-53=

−4

g

​

−53, equals, start fraction, g, divided by, minus, 4, end fraction, minus, 5

g =g=g, equals

Answers

Answer:

g=-32

Step-by-step explanation:

We are given that

3=(g)/(-4)-5

We have to find the value of g.

3=(g)/(-4)-5

(g)/(-4)=3+5

Using addition property of equality

(g)/(-4)=8

By addition property of integers

g=8(-4)

By using multiplication property of equality

g=-32

Hence, the value of g=-32

Which of the following expressions is a factor of the trinomial x^3 - x^2 - 6x l. x II. x - 3
III. x + 2

Answers

Answer:

Both

Step-by-step explanation:

First,let's resolve the expression into factors

x^3-x^2-6x

x(x^2-x-6)

x(x^2-3x+2x-6)

x(x(x-3)+2(x-3))

x(×+2)(x-3)

Therefore,both of them are the factors of the expression
