Step-by-step explanation:
An expression that combines numbers and operations is a mathematical statement that represents a calculation or computation.
An expression can involve various arithmetic operations such as addition, subtraction, multiplication, division, exponentiation, and more.
Here are some examples of expressions:
Addition: 5 + 3
Subtraction: 10 - 2
Multiplication: 4 × 6
Division: 20 / 5
Exponentiation: 2³ (2 raised to the power of 3)
Combination: (5 + 3) × 2
In the last example, the expression combines addition and multiplication. Parentheses can be used to indicate the order of operations, ensuring that calculations are performed correctly according to mathematical conventions (e.g., multiplication before addition).

Answer: She would have to burn between 220 and 240 calories per minute to have a calorie burn rate between those of Martin and Paul.
Step-by-step explanation:
Martin:
360 calories / 30 min = 12 calories/min
Paul:
165 calories / 15 min = 11 calories/min
Kara:
Needs to burn between 11 and 12 calories/min, so we'll calculate the range:
11 calories/min x 20 min = 220 calories (minimum # calories she can burn)
12 calories/min x 20 min = 240 calories (maximum # calories she can burn)
The value of x will be;
⇒ x = 7/2
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
BD is an angle bisector.
Now,
In ΔBFG and ΔBFE;
∠G = ∠E = 90°
BF is common line.
∠GBF = ∠ FBE
Thus, ΔBFG ≅ ΔBFE
Hence, FG = FE
Substitute the values, we get;
⇒ FG = FE
⇒ 2x + 6 = 4x - 1
⇒ 6 + 1 = 4x - 2x
⇒ 7 = 2x
⇒ x = 7/2
Thus, The value of x will be;
⇒ x = 7/2
