Answers

Answer 1

Step-by-step explanation:

ab                 =>    (5)(6) = 30

b + 3             =>    6 + 3 = 9

a + b + c       =>    5 + 6 + 7 = 18

3b + 4          =>    3(6) + 4 = 22

5a - c           =>    5(5) - 7 = 18

Answers

Answer:

5(5b-1z)

Step-by-step explanation:

we know that we have 25b and -5z

we will have to multiply 5 with everything that is between the () mark, and still should have the same amount of "b"s and "z"s

(to find the numbers, you will have to divide, in this case by 5

25/5= 5 -> 5b

5/5=1 -> 1z

--> 5(5b-1z) = 25b-5z

Solve this addition question by substituting numbers for the given letters to find the value of START. Each letter represents a unique digit.

JOAN+CAN=START

Answers

Solved the given question by addition rules and the value of START is 10430.

Given-

The given problem is from the alphabetical puzzle. In the given problem the equation given is,

JOHN + CAN = START.

It can be written as,

   J  O  H  N

+      C  A  N

__________

S  T  A  R  T

__________

S must be 1, because, even if we assume all the missing digit are 9 ( the largest possible value), the sum will be smaller than than 10999 or equal to the 10998.

Similarly the value of T must be 0 because, even if we assume all the missing digit are 9 ( the largest possible value), the sum will be smaller than than 10999 or equal to the 10998.

Now as the T is two times in the solution of addition, and the value of T is 0 as we found. But T is the addition of N and N. Hence N must be 5 to make the addition 10 for the 0 value of the T.

                N

            +  N

            ____

              1 0

            ____

J must be 9 with carried 1 to make the T 0.

A must be more than 10 to have a carry on J. A can not 1 as S has 1 digit. 2 and 3 disturbs the equation. Thus a must be 4. and for this o and c must be 6 and 7.

If a is 4 than the H and R must be 8 and 3.

The sum will look like,

  9  6  8  5

 +   7  4  5

________

1  0  4  3  0

_________

Hence, solved the given question by addition rules and the value of START is 10430.

The account balance of each of three children at the end of a month is shown below: John has −$2.75
Cheryl has −$3.00

Andrew has as much savings in his account as the amount John owes the bank.
Part A: On a blank paper, draw a number line from −4 to +4. Plot points on the number line to show the account balances of the three children. Label the points using the name of each child. Describe in detail how you created and labeled this number line, and what it looks like in detail. (5 points)

Part B: Determine whether John or Cheryl owes the bank more. Use absolute values and inequalities to write statements that justify your conclusion. (5 points)

(HELP I JUST NEED PART B :)) (and give a complete explanation please!! i wanna learn so i dont ask questions the next time.)

Answers

Cheryl owes more money to the bank. |-3| = 3 and |-2.75| = 2.75. As you can see Cheryl's amount of money is greater when you find the absolute value of it, but since it was negative it means that she actually owes more money.

327*100=30x

32700=30x

÷30-÷30

= 1090x

do 1090 8s the overall answer

ANSWER: $425.10

The mark down is 30% so we need to find how much that is then add it to the price it is now.

30% of 327 = 98.1

So now we need to add 98.1 to 327

98.1 + 327 = 425.10
