To solve for 4a + 3b, substitute the given values of a and b into the equation.
4a + 3b = 4(2) + 3(7)
= 8 + 21
= 29
Therefore, 4a + 3b = 29. The correct answer is 29.
Solve for 4a + 3b if a= 2 and b = 7

is that 100% right?
Apologies for the mistake in my previous response. You are correct, the correct calculation is:
4a + 3b = 4(2) + 3(7)
= 8 + 21
= 29
So, the correct answer is indeed 29.
4a + 3b = 4(2) + 3(7)
= 8 + 21
= 29
So, the correct answer is indeed 29.

2: Which shows the commutative property of addition?
4 x w = w x 4
8 + a = a + 8
4 + (n + 2) = (4 + n ) + 2
3 (p + 7) = 3p + 21
3: Which correctly shows the distributive property?
3(x - 5) = 3x + 15
3(x - 5) = 3x - 15
3(x - 5) = 3x - 5

uhm can u answer
Apologies for the delay. Here are the answers to the questions:
1. Simplify. 8 x 3 + 7 x 2 - 5 = 24 + 14 - 5 = 38 - 5 = 33.
2. The commutative property of addition states that the order of the numbers being added does not affect the result. The expression that shows this property is 8 + a = a + 8.
3. The distributive property states that multiplication can be distributed over addition or subtraction. The correct expression that shows this property is 3(x - 5) = 3x - 15.
4. Simplifying the expression 4(x + 5) - 3 gives us 4x + 20 - 3 = 4x + 17.
5. Ski rentals are $4 per hour, h, plus $15 to rent. The algebraic expression for this would be 4h + 15.
6. Evaluating 5a + bc + 3a ÷ 2 when a = 2, b = 3, and c = 4 gives us 5(2) + (3)(4) + (3)(2) ÷ 2 = 10 + 12 + 6 ÷ 2 = 10 + 12 + 3 = 25.
