Answer:

given ,

number of coins in bag A = 5x

number of coins in bag B = 3x

_____________________________________

According to Question ,

8 coins are taken from Bag B and put into Bag A

The ratio of coins in Bag A to Bag B is now 11 : 5

therefore ,

$\frac{5x + 8}{3x - 8} = \frac{11}{5} \\ \\ 5(5x + 8) = 11(3x - 8) \\ \\ 25x + 40 = 33x - 88 \\ \\ 33x - 25x = 40 + 88 \\ \\ 8x = 128 \\ \\ x = \cancel\frac{128}{8} \\ \\ \fbox{x =16}$

now ,

$no. \: of \: coins \: in \: bag \: A = 5x \\ \dashrightarrow{5 \times 16 = 80 \: coins}$

$number \: of \: coins \: in \: bag \: B = 3x \\ \dashrightarrow{3 \times 16 = 48 \: coins}$

$total \: number \: of \:coins = 80 + 48 \\ \dashrightarrow{ 128 \: coins}$

hope helpful :D

Answer:

a. (2x - 3)(x - 4)

b. 17 m, 6 m

c. 46 m

Step-by-step explanation:

2x² - 11x + 12 = (2x - 3)(x - 4)

2x - 3 = 2(10) - 3 = 17

x - 4 = 10 - 4 = 6

P = 2L + 2W = 2(17) + 2(6) = 46

UW; Converse of the Isosceles Triangle Theorem

This is the answer because angles T and W are congruent. Meaning that they make an isosceles triangle. The two sides connecting to those angles should be congruent. Therefore UT and UW are congruent.

Elise and her dad are planning to attend the state fair. An adult ticket is $21.00. The price of an adult ticket is $10.00 more

solong [7]

Answer:

C. two thirds x + 10 = 21

Step-by-step explanation:

Given

Price of adult ticket = $21.00

Let x be the price of student ticket

Then

two third of the student ticket will be:

$\frac{2}{3} x$

The statement $10.00 more than two third of student ticket:

$\frac{2}{3} x+10$

As we are given in the question that the adult ticket price is $21.00 and the second explanation is th equation formed by the given statement

So, both will be equivalent

$\frac{2}{3} x+10 = 21$

Solving this equation for x will give us the price for the student ticket.

Hence,

C. two thirdsx + 10 = 21 is the correct answer ..
