Abigail is 8 years older than Cynthia. Twenty years ago Abigail was three times as old as Cynthia. How old is each now?
irina [24]
A - age of Abigail
C - age of Cynthia

A = C + 8

A - 20 = 3 (C - 20) 

A - 20 = 3C - 60  

C + 8 - 20 = 3C - 60

C - 12 = 3C - 60                A = C + 8

2C = 48                             A = 24 + 8 

C = 24 years                     A = 32 years

A restaurant adds a 20% tip to the bills of parties of 6 or more people. Suppose a server waits on five such tables. The bill
castortr0y [4]

Answer:

$218.70

Step-by-step explanation:

You need to first convert the percentage to the decimal.

20% = 0.2

Now, you need to find 20% of each bill by multiplying each bill by 0.2.

0.2(185.45) + 0.2(205.20) + 0.2(195.05) + 0.2(245.80) + 0.2(262.00)

Because of the distributive property, you can add up the bills and multiply the sum by 0.2.

0.2(185.45 + 205.20 + 195.05 + 245.80 + 262.00)

0.2(1093.50)

218.7

The waiter made $218.70 in tips.

nordsb [41]

Answer:

The bottom question is wrong. You have to multiply 8 to get the amount earned. But the rest is correct.

Step-by-step explanation:

6.25 x 8 = 50

12.5 x 8 = 100

18.75 x 8 = 150

25 x 8 = 200

31.25 x 8 = 250

Leni [432]

Answer:

2x+5 r. 13

Step-by-step explanation:

So using long division, you can solve for the quotient and the remainder.

Please look at the attached for the solution.

Step 1: need to make sure that you right the terms in descending order. (If there are missing terms in between, you need to fill them out with a zero so you won't have a problem with spacing)

Step 2: Divide the highest term in the dividend, by the highest term in the divisor.

Step 3: Multiply your result with the divisor and and write it below the dividend, aligning it with its matched term.

Step 4: Subtract and bring down the next term.

Repeat the steps until you cannot divide any further. If you have left-overs that is your remained.
