Brandon needs $8$ boxes of spinners for his fishing club. The cost of each box is $\$9$. How much will Brandon pay?

$$8 × \$9 =$$

Look at how Brandon solved the problem. Find and describe his error.

$$8 × 9 = (4 × 9) + (5 × 9)$$

$$8 × 9 = 36 + 45$$

$$8 × 9 = 81$$

Evaluate each exponential expression.

$$2 ^ { - 6 }$$

13. Ada writes 10 + 8 = 18 on the board. Maria wants to use the Commutative Property of Addition to rewrite Ada’s addition sentence. What number sentence should Maria write?

The formula F = 1.8C + 32 allows you to find the Fahrenheit (F) temperature for a given Celsius (C) temperature. Solve the equation for C to produce a formula for finding the Celsius temperature for a given Fahrenheit temperature.

The formula F=1.8C_32 gives the temperature in degrees Fahrenheit (F) for a given temperature in degrees Celsius (C). There is one temperature for which the number of degrees Fahrenheit is equal to the number of degrees Celsius. Write an equation you can solve to find that temperature and then use it to find the temperature. _
