Question

A=7÷ a×5+38; 49×a+26.

Answer 1

7×5+38=72

49×7+26=369

Answer 2

To solve the expressions, let's first clarify the order of operations (PEMDAS/BODMAS) which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division, and Addition and Subtraction.

Now, let's solve the expressions step by step:

Expression 1: A = 7 ÷ a × 5 + 38

1. Perform the division first: A = (7 / a) × 5 + 38

2. Perform the multiplication next: A = (7 * 5) / a + 38 A = 35 / a + 38

Expression 2: 49 × a + 26

Now we don't have any variables, so this expression is already simplified.

Now, we don't have enough information to solve these expressions further as they both contain the variable 'a'. If you have any specific value for 'a', you can substitute it into the expressions to get the numerical values.

For example, if 'a' is 5, then:

1. A = 35 / 5 + 38 A = 7 + 38 A = 45

2. 49 × 5 + 26 245 + 26 271

But without a specific value for 'a', we cannot obtain a numerical result. Please provide the value of 'a' if you want to get the final numerical answers for these expressions.
