Create an expression to represent the following<br><br> (picture is included below)
zheka24 [161]

Answer:

7) x + 0.09x, where x is the price of the car

8) x + 0.05x where x is the price of clothing

9) It will take michael about 9.14 minutes to eat 32 cookies.

Step-by-step explanation:

7) 9% of x is the same as 0.09x, so you can write this:

x + 0.09x, where x is the price of the car

8) same thing for this one

x + 0.05x where x is the price of clothing

9) michael can eat cookies at a rate of 21 cookies per 6 minutes, or \frac{21}{6}

Because he will be eating them at the same pace, you can write an equation and solve for the variable:

\frac{21}{6} = \frac{32}{y}

cross multiply the proportion:

21 × y = 32 × 6

solve:

21y = 192

y ≈ 9.14

It will take michael about 9.14 minutes to eat 32 cookies.

This works because they both simplify to 3.5 cookies per minute

\frac{21}{6} = 3.5

\frac{32}{9.14} = 3.5

The foundational concept of algebra is to use the alphabetical letters to find the unknown number.

Algebra is the concept that uses the alphabetical letters such as x, y, z, etc. to calculate the unknow numbers. here the letters are also called as variables. The values that are known in the expression as termed as constants.

The general operations performed on the algebra is

  • Addition = x + y
  • Subtraction = x - y
  • Multiplication = x * y
  • Division = x / y

Here the alphabets x and y are called variables.

Order of operations:

The order of operation in algebra is given as follows

  • Perform all the operations inside the brackets
  • Perform the operations on roots and exponents
  • Perform all the division and multiplication operations moving from left to right
  • Perform all the addition and subtraction operations from left to right.
