Answer:

\boxed{  \bold{ \huge{ \boxed{ \sf{14x + 4}}}}}

Step-by-step explanation:

\sf{(5x + 2) - ( - 9x - 2)}

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

\dashrightarrow{ \sf{5x + 2  + 9x + 2}}

Collect like terms

\dashrightarrow{ \sf{14x + 2 + 2}}

Add the numbers : 2 and 2

\dashrightarrow{ \sf{14x + 4}}

Hope I helped!

Best regards! :D

3. A restaurant bill of $350 was paid using $5 notes and $50 notes. The total number of
Sonbull [250]

The number of $5 notes is 10 and $50 notes is 6

Step-by-step explanation:

Let x be the number of $5 notes

and

y be the number of $50 notes

Then according to given statements

"The total number of notes used was 16."

x+y=16    Eqn 1

"A restaurant bill of $350 was paid using $5 notes and $50 notes."

5x+50y=350       Eqn 2

From\ Eqn\ 1\\x+y=16\\y=16-x\\Putting\ y=16-x\ in\ equation\ 2\\5x+50(16-x)=350\\5x+800-50x=350\\-45x+800=350\\Subtracting\ 800\ from\ both\ sides\\-45x+800-800=350-800\\-45x=-450\\Dividing\ both\ sides\ by\ -45\\\frac{-45x}{-45}=\frac{-450}{45}\\x=10

Putting x=10 in equation 1

10+y=16\\y=16-10\\y=6

So,

The number of $5 notes is 10 and $50 notes is 6

barxatty [35]

Answer:

45%

Step-by-step explanation:

The formula to work out the decrease is:

Percentage Decrease= actual decrease / original amount X 100%

1) So firstly, we have to work out the decrease, to do this we have to do is do $750-$412.50= $337.50

2) We can now substitute this into our formula which will now be. (We will also add the original amount, which is $750.00)

Percentage Decrease= 337.50 / 750.00 X 100% = 45

The percentage decrease is 45%
