Answer:

Step-by-step explanation:
Let
x ----> the cost of a pretzel
we know that
The phrase" $3 more than four times the cost of a pretzel" is equal to multiply the cost of a pretzel x by 4 and adds the number 3
so
The algebraic expression is

Answer:
n = 13
Step-by-step explanation:
1. (9n-8) and (6n-7) combined equal 180 degrees, and we can translate that into an equation and then solve it:
2. (Solving)
Step 1: Simplify both sides of the equation.
Step 2: Add 15 to both sides.
Step 3: Divide both sides by 15.
Therefore, n = 13.
This is an exercise on Thermometric scales.
We have as data:
We apply the following formula:

We substitute data in the formula:

First multiply 9 x 220, then the result of this division is divided by 5.

Therefore the cake recipe that should be baked at 220 °C for 45 minutes, on the Fahrenteir scale is 428 °F. Which indicates that it will be very hot.
