QuestionLoop 1 Name \qquad Tuesday
1. What is the difference between the highest and lowest temperature shown on the thermometer? A. 28 degrees B. 23 degrees C. 17 degrees D. Cannot be determined
2. Solve the following equation for xx. 0.3x−5=10.3 x-5=1

Studdy Solution

STEP 1

1. The problem consists of two separate questions.
2. For the first question, we assume there is a thermometer with visible temperature readings.
3. For the second question, we need to solve a linear equation for x x .

STEP 2

1. Determine the difference between the highest and lowest temperature.
2. Solve the linear equation for x x .

STEP 3

Determine the difference between the highest and lowest temperature.
Since the thermometer readings are not provided, we cannot determine the exact temperatures. Therefore, the answer to the first question is:
D. Cannot be determined

STEP 4

Solve the linear equation for x x .
Given equation: 0.3x−5=1 0.3x - 5 = 1

STEP 5

Isolate the variable term by adding 5 5 to both sides of the equation:
0.3x−5+5=1+5 0.3x - 5 + 5 = 1 + 5 0.3x=6 0.3x = 6

STEP 6

Solve for x x by dividing both sides by 0.3 0.3 :
x=60.3 x = \frac{6}{0.3}
To simplify, multiply the numerator and the denominator by 10 to eliminate the decimal:
x=603 x = \frac{60}{3} x=20 x = 20
The solution to the equation is:
20 \boxed{20}
