" 4c * d ÷ d " =
" (4c*d) /d " ;

= " (4cd) /d " ; The "d's" cancel out to "1" ; since "d ÷ d = 1 " ;

and we are left with: " 4c " .

on a certain hot Summer's Day 613 people use the public swimming pool the daily prices are $1.75 for children $2.25 for adults t

Elodia [21]

389 children and 224 adults were at the pool that day.

Step-by-step explanation:

Cost of one child ticket = $1.75

Cost of one adult ticket = $2.25

Total people = 613

Total receipts worth = $1184.75

Let,

Number of children = x

Number of adults = y

According to given statement;

x+y=613 Eqn 1

1.75x+2.25y=1184.75 Eqn 2

Multiplying Eqn 1 by 1.75

$1.75(x+y=613)\\1.75x+1.75y=1072.75\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(1.75x+2.25y)-(1.75x+1.75y)=1184.75-1072.75\\1.75x+2.25y-1.75x-1.75y=112.00\\0.50y=112.00$

Dividing both sides by 0.50

$\frac{0.50y}{0.50}=\frac{112.00}{0.50}\\y=224$

Putting y=224 in Eqn 1

$x+224=613\\x=613-224\\x=389\\$

389 children and 224 adults were at the pool that day.

pychu [463]

Answer:

Step-by-step explanation:

$8a - 5b - (6a - 9b)$

When there is a (-) in front of an expression in parentheses, change the sign of each term in the expression.

$8a - 5b - 6a + 9b$

Collect like terms

$2a + 4b$

Factor out 2 from the expression

$2(a + 2b)$
