Step-by-step explanation:

1)

P = 2(l + w)

P = 2(3a + 3 + 8a - 12)

P = 2(11a - 9)

P = 22a - 18

2)

P = 22a - 18

P = 22(3) - 18

P = 66 - 18

P = 48

3)

P = a + b + c

P = 3b + 7 + 7b - 2 + 7b - 2

P = 17b + 3

Suppose you want to treat your office team to lattes at a local coffee shop. The drinks are $4.25 each,
plus you plan to buy a $3 scone for yourself. You also tip the barista 10% and have to pay 8.25% sales tax.
How many lattes can you afford if you have $60 to spend?

Answers

Answer: 10 lattes

lmk if this is incorrect

Step-by-step explanation:

sales tax: 60(.0825)=4.95

tip: 60(.10)=6

scone: 3

total excluding lattes: 4.95+6+3=13.95

total left to spend on lattes: 60-13.95=46.05

amount of lattes you can afford: 46.05/4.25=10.835294.....

Answer:

11 lattes and 1 scone

Step-by-step explanation:

11×4.25= 46.75+3.00= 49.75

49.75×8.25%= $53.85

10% of $53.85 is $5.38

53.85+5.38= $59.23

You will have .77 left

The answer is K=-1/5

You suppose to divide both sides by 3.

Move the constant to the left-hand side and change its sign Use a^2 + 2 ab+ b^2 = (a+b)^2 to factor the expression.

The only way an exponentiation can be 0 is when the base equals 0.

Move the constant to the right-hand side and change its sign.

Divide both sides of the equation by 5.

Ben score is 56 out of 79 marks what is his score as a percentage

Answers

Answer:

71%, without rounding 70%

Step-by-step explanation

We know our total number of marks is 79 if we only get 56 out of 79 we take 56/ 79. You'll end up with a number of 0.7088. You will ALWAYS end up with a decimal point. Because its a percentage we move the decimal point over 2 spots making the number 070.88 the 0 in front of of the 70.88 gets removed so you're left with 70.88 so rounded it would be 71%. Hope this helps

Answer:

70.88% or 70.9%(if rounded off)

Step-by-step explanation:

1. 100 ÷ 79 = 1.2658227848

2. 1.2658227848 × 59 = 70.8860759494

3. 70.88 rounded off to the nearest tenths is 70.9
